Our engineering team has mastered these challenges, delivering SS pressed components with tight tolerances, burr-free edges, and impeccable surface finishes that meet the most demanding international specifications — including 2B, No.4 brushed, mirror-polished, and electropolished finishes.

Stainless Steel Stamped Parts

Stainless steel stamped parts deliver the ideal combination of dimensional consistency, corrosion resistance, and high-volume repeatability that demanding industries require. Produced through precision die-stamping operations, these parts maintain tight tolerances across large production runs, making them a preferred choice for electrical, automotive, instrumentation, and industrial assembly applications. Whether the requirement is a simple bracket or a complex multi-feature component, stainless steel stamped parts offer a cost-effective alternative to machined or cast equivalents without sacrificing structural integrity or surface quality.

Stainless Steel Stamping

Stainless steel stamping is a cold-forming metal fabrication process in which sheet or coil stock is fed through progressive or compound dies to produce net-shape or near-net-shape components at speed and scale. The process is well-suited to stainless steel alloys because it harnesses the material’s natural work-hardening characteristics, producing parts with excellent strength-to-weight ratios and smooth, burr-minimised edges. Modern stainless steel stamping combines precision tooling design with servo-controlled press technology to achieve micron-level repeatability, reduced material waste, and consistent part geometry from the first piece to the millionth.

Stainless Steel Stamped Components

Stainless steel stamped components span a broad range of geometries and functional applications — from contact springs, terminal plates, and shielding clips in electronics, to fastener washers, clamps, and structural gussets in heavy engineering. What unites them is the ability of the stamping process to impart precise form, consistent wall thickness, and excellent surface finish to each piece, all while leveraging the inherent hygiene, oxidation resistance, and mechanical durability of stainless steel. For OEMs and system integrators sourcing sub-assemblies globally, stainless steel stamped components represent a reliable, scalable supply solution.

Stainless Steel 304 Pressed Parts

Grade 304 stainless steel is the most widely specified austenitic alloy for pressed parts, valued for its balanced combination of formability, weldability, and resistance to atmospheric and mild chemical corrosion. Its low carbon content and stable austenitic microstructure allow the material to be drawn, blanked, and formed into complex geometries without cracking or excessive springback, making it highly amenable to progressive die stamping. Stainless steel 304 pressed parts find extensive use in food processing equipment, architectural hardware, electrical enclosures, and general industrial assemblies where hygiene and long service life are equally important.

Stainless Steel 316 Pressed Parts

Stainless steel 316 pressed parts are the specification of choice wherever elevated corrosion resistance is non-negotiable — particularly in marine environments, chemical processing plants, pharmaceutical manufacturing, and offshore installations. The addition of molybdenum to the 316 alloy significantly enhances resistance to pitting and crevice corrosion caused by chlorides and aggressive process media, making it far superior to 304 in such conditions. Although 316 requires slightly greater press tonnage due to its higher yield strength, precision stamping in this grade produces components that offer outstanding longevity and performance even under continuous exposure to saline, acidic, or high-humidity operating environments.

SS 304 vs SS 316 – Choosing the Right Grade

SS 304 (18/8 stainless) is the most widely used austenitic stainless steel, offering excellent corrosion resistance in most environments, good formability, and cost-effectiveness. It is ideal for food processing equipment, architectural hardware, general industrial parts, HVAC components, and white goods.

SS 316 (18/10/2 stainless with molybdenum) provides superior resistance to pitting corrosion and crevice corrosion, particularly in chloride-rich environments (seawater, marine, chemical processing). SS 316 is the material of choice for pharmaceutical equipment, marine hardware, chemical plant components, and medical devices.

Our Technical Expertise in Stainless Steel Stamping

SS 304 and SS 316 work-harden significantly during forming — their tensile strength can increase by 50–100% during deep forming operations. Our die designers account for this by using larger punch-die clearances (typically 10–15% per side for SS vs. 5–8% for brass), stronger tool steels (D2, M2, PM steels), and slower press speeds for deep forming operations. Our presses are equipped with precision servo feeds and lubrication systems to ensure consistent blank feeding and reduced die wear.

We have manufactured stainless steel stampings for food & beverage processing equipment, pharmaceutical clean rooms, marine hardware, architectural cladding, HVAC brackets, automotive exhaust components, medical instrument housings, surgical trays, chemical dosing pump parts, and many other precision applications.

What Separates Us from Other Stainless Steel Stamping Manufacturers

Our dedicated stainless steel press lines use tool steels, clearances, feeds, and lubrication systems specifically calibrated for austenitic SS — not adapted from carbon steel or brass operations. This means fewer die failures, better edge quality, and more consistent springback control. Our quality team has extensive experience with the demanding standards of the food, pharmaceutical, and marine industries — sectors where surface integrity, traceability, and material certification are non-negotiable. We have never had a recalled shipment in 30 years of export — a record we are proud of and intend to maintain.

Our Flexibility to Customize SS Stamped Parts

We manufacture SS stampings in any shape, size, and specification from customer-supplied drawings or samples. Custom surface finishes (bead blast, No.4 brushed, electropolished, passivated per ASTM A967), selective masking for plating, special flatness requirements (spring-flat grinding available), and custom part marking (laser etching, electrochemical etching) are all available. We also offer prototype-to-production scale-up with no change in part drawing or specification.

Export Packaging for Stainless Steel Stampings

SS parts are individually separated with PE foam inter-leaf or silicone-free tissue paper to preserve surface finish integrity. Parts are packed in custom-sized corrugated inserts, bubble-wrapped for extra protection, and sealed in moisture-proof poly bags. Export cartons are reinforced, palletized, and labeled with full traceability data. For surface-critical parts (No.4 or mirror finish), we use individual peel-off protective film backing on all faces before packing.

Top Q&A – Stainless Steel 304 & 316 Stamped Parts

Q1: What is the difference between SS 304 and SS 316 for stamped parts?
A: SS 304 is the standard austenitic grade for general industrial use. SS 316 adds molybdenum for enhanced chloride and pitting corrosion resistance, making it essential in marine, pharmaceutical, and chemical environments.

Q2: What is the advantage of 304L and 316L over standard 304 and 316?
A: The “L” grades have reduced carbon content (<0.03%), which prevents sensitization during welding and reduces intergranular corrosion risk. Preferred for welded assemblies in corrosive environments.

Q3: What surface finishes are available for SS stampings?
A: 2B (standard mill finish), No.4 brushed, No.8 mirror, bead blast, electropolished, passivated (per ASTM A967), and PVD coated finishes are all available.

Q4: Can you maintain the original 2B surface finish on stamped parts?
A: Yes. We use protective adhesive film on sheet material during punching and forming, and use clean, non-contaminating tooling to preserve 2B finish integrity.

Q5: What is the springback in stainless steel and how do you manage it?
A: SS has a high elastic modulus and work-hardening rate, causing significant springback after bending. We overbend to compensate, use coining, and perform FEA simulation to predict and counteract springback in die design.

Q6: Can you produce food-grade SS 316 stampings?
A: Yes. We produce food-contact-safe SS 316 stampings with electropolished and passivated surfaces, meeting FDA 21 CFR, EU Regulation 1935/2004, and 3-A Dairy standards.

Q7: Do you supply EN 10204 3.1 material certificates?
A: Yes. We supply EN 10204 Type 3.1 (mill certificate with inspection body certification) for all SS 304 and 316 materials on request.

Q8: Can you stamp SS 316 parts for seawater environments?
A: Yes. SS 316 (and 316L) with passivation and/or electropolishing treatment is our standard recommendation for seawater and marine environments.

Q9: What tool steel do you use for SS stamping dies?
A: We use D2 (cold work tool steel), M2 high-speed steel, and PM tool steels (like Bohler K110, K360) for long-life SS stamping dies. TiN, TiAlN coatings extend die life further.
