Types of Stainless Steel Sheet Metal Components We Manufacture

Stainless Steel Deep-Drawn Components

We produce deep-drawn SS cups, shells, canisters, and housings using progressive transfer tooling on hydraulic presses up to 400 tonnes. Deep drawing ratios up to 2.5:1 are achievable in SS 304, with careful control of material grain direction and lubrication.

Stainless Steel Stamped Brackets and Clips

From 0.5 mm to 4 mm SS sheet, we punch, blank, and form brackets, clips, clamps, mounting plates, and support brackets using compound and progressive dies. Punching tolerances to ±0.05 mm are routine.

Stainless Steel Laser-Cut Parts

Flat blanks, panels, covers, and profiles in SS sheet are cut using fibre laser machines capable of cutting up to 8 mm thick stainless. Laser cutting offers burr-free edges, tight tolerances, and rapid turnaround for prototype and small-batch orders.

Stainless Steel Formed and Bent Assemblies

CNC press brakes form stainless sheet into channels, angles, enclosures, frames, and cabinets. We work to customer DXF unfold files and can advise on bend radii and springback compensation for different SS grades.

Stainless Steel Washers and Discs

Blanked SS washers, discs, and gaskets in 304, 316, and 430 to BS 4320, DIN 125, or custom sizes. Available with plain, polished, or passivated finish.

Stainless Steel Perforated and Mesh Panels

Perforated stainless sheet panels for filtration, screening, and architectural applications with hole patterns ranging from 1 mm round to custom slots and hexagonal patterns.

Frequently Asked Questions — SS Sheet Metal Parts

Q1: What stainless steel grades are suitable for sheet metal pressing?

The most widely pressed grades are SS 304 (1.4301) for general use, SS 304L for welded assemblies, SS 316 (1.4401) for chemical and marine applications, SS 316L for pharma and offshore, and SS 430 (1.4016 ferritic) for appliances and decorative uses. SS 304 is the most economical for most forming operations due to its excellent ductility and work-hardening characteristics.

Q2: What sheet thicknesses can you press in stainless steel?

We routinely process SS sheet from 0.3 mm foil up to 12 mm plate. Sheets from 0.3–3 mm are best suited for high-speed blanking and progressive die stamping. Thicknesses from 3–8 mm are typically handled on hydraulic presses. Above 8 mm, laser cutting combined with CNC press brake bending is the preferred process.

Q3: What is the tooling cost for a custom stainless steel pressing?

Tooling costs vary from USD 300–500 for a simple blanking tool to USD 5,000–15,000 for a multi-stage progressive die in SS 304 or 316. Stainless steel tools typically cost 20–40% more than equivalent brass or mild steel tools due to the higher abrasion wear on dies. Tooling is owned by the customer and fully amortisable over production quantities.

Q4: Why does stainless steel spring back more than mild steel during pressing?

Stainless steel has a higher elastic modulus and significant work-hardening during plastic deformation, causing greater elastic spring-back on release of press force. Tooling for SS must account for this by over-bending (typically 2–5° over the required angle). Our tool designers calculate spring-back compensation for each alloy and thickness before cutting production tools.

Q5: Can you supply stainless steel pressed parts with PED compliance?

Yes. For European Pressure Equipment Directive (PED) projects, we can supply SS sheet metal parts with EN 10088-2 material certifications, 3.1 inspection certificates, and pressure test documentation. Design verification and ATEX compliance documentation is the customer’s responsibility as the equipment manufacturer.

Q6: Do you offer laser cutting as an alternative to press tooling for prototypes?

Absolutely. Laser cutting requires no tooling investment and is ideal for prototype quantities of 5–200 pieces, delivering parts within 5–7 working days from approved DXF files. Once the design is finalised and volumes justify tooling, we transition to press tool stamping for significant unit cost reduction. Both services are available from our Jamnagar facility.

Q7: What is the difference between a compound die and a progressive die for SS stampings?

A compound die performs blanking and piercing simultaneously in a single stroke — ideal for simple washers, discs, and flat blanks where the inner and outer profiles are cut in one hit, giving very flat parts. A progressive die performs multiple operations (blank, pierce, form, bend) in sequential stations as the strip advances — suited for complex formed parts requiring multiple features, offering higher productivity for large volumes.

Q8: Can you weld stainless steel sheet metal assemblies?

Yes. We offer TIG (GTAW) welding, spot welding, and MIG welding on SS 304, 316, and 430 sheet metal assemblies. TIG welding with argon back purging is used for sanitary and pharmaceutical applications requiring full weld penetration and oxide-free back beads. Post-weld passivation or electro-polishing is available to restore corrosion resistance in the weld heat-affected zone.

Q9: Are your SS pressed parts RoHS and REACH compliant?

Yes. All SS 304, 316, and 430 alloys we use conform to RoHS Directive (2011/65/EU) and REACH SVHC requirements. They contain no restricted substances (Cr6+, Pb, Cd, Hg) above threshold levels. Certificates of conformance with REACH and RoHS declarations are available with each shipment — important for US and EU market entry compliance.

Q10: What is the minimum order for SS sheet metal pressed parts?

For laser-cut prototype parts: no minimum — from 1 piece. For press tool stamped parts: minimum of 500–1,000 pieces per design to justify tooling setup. For repeat production orders using existing tools, minimum order quantities start from 200–500 pieces depending on part complexity. We offer flexible scheduling for blanket orders with monthly call-off releases.
