Stainless Steel 316 Stamped Parts –Stainless Steel 316 Stamped Components

Stainless Steel Fittings India manufactures a comprehensive range of SS 316 and SS 316L stamped parts and components including precision brackets, mounting plates, clips, clamps, retainers, busbar components, and marine hardware. Designed for offshore platforms, chemical process plants, coastal power installations, and marine electrical systems where chloride exposure and pitting corrosion rule out standard SS 304 construction. Supplied to electrical OEMs, EPC contractors, power utilities, and industrial distributors worldwide. Price: US$ 11.50/Kilogram

SS 316 stamped parts and components are precision-formed from molybdenum-alloyed austenitic stainless steel sheet and strip, providing superior resistance to chloride pitting, crevice corrosion, and general chemical attack compared with standard SS 304. Manufactured by precision blanking, forming, and coining on progressive and single-station presses, SS 316 stamped components are specified wherever service exposure includes seawater, de-icing salts, marine atmospheres, or moderate concentrations of acids and chlorides.

SS 316 Precision Stamped Brackets & Mounting Plates

SS 316 brackets, mounting plates, and support arms are precision stamped for offshore platform equipment mounting, coastal switchyard hardware, and chemical process equipment support where SS 304 would suffer pitting over the equipment’s service life. Formed to close angular and hole-position tolerances for direct bolt-up assembly without secondary machining.

SS 316 Stamped Clips, Clamps & Retainers

Spring clips, cable retainers, and P-clamps stamped from SS 316 strip provide corrosion-resistant cable and pipe securing in marine, offshore, and chemical plant environments. Consistent spring temper across production batches ensures reliable retention force throughout the service life of the installation.

SS 316 Stamped Electrical & Busbar Components

Busbar supports, terminal connectors, and electrical hardware stamped from SS 316 are used in coastal and offshore switchgear where standard plated steel hardware would corrode and compromise electrical contact integrity. Non-magnetic austenitic structure avoids induced eddy current heating in high-current busbar assemblies.

SS 316 Stamped Marine & Offshore Hardware

Deck hardware, handrail brackets, hatch hardware, and topside equipment mounting components are stamped from SS 316 for shipboard and offshore platform service where continuous salt spray exposure demands maximum practical corrosion resistance within the austenitic stainless steel family.

SS 316 Stamped Gaskets & Shim Components

Metallic gaskets, spiral-wound gasket windings, and shim components stamped from SS 316 provide chemical compatibility with a broad range of process fluids in petrochemical and offshore process piping, where gasket material selection is critical to flange joint integrity.

SS 316L Low-Carbon Stamped Parts for Welded Assemblies

SS 316L (low-carbon) stamped components are specified where post-stamping welding is required, since the reduced carbon content prevents sensitization and chromium carbide precipitation at grain boundaries during welding, maintaining corrosion resistance in the heat-affected zone.

Custom SS 316 Stamped Components to Drawing

Custom SS 316 stamped parts are manufactured to customer drawings for OEM-specific brackets, connectors, and hardware where standard catalogue items do not meet the exact dimensional or functional requirement of the application.

Why SS 316 for Corrosive & Marine Environments

SS 316 contains 2–3% molybdenum in addition to the chromium-nickel content of SS 304, which significantly improves resistance to chloride-induced pitting and crevice corrosion. This makes SS 316 the standard material choice for offshore platforms, coastal switchyards, desalination plants, and marine vessels where SS 304 would show visible pitting within a few years of service.

SS 316 vs SS 316L: Carbon Content & Weldability

SS 316 contains up to 0.08% carbon while SS 316L is restricted to 0.03% maximum, preventing chromium carbide precipitation at grain boundaries during welding (sensitization). SS 316L is specified for stamped parts that will be welded into larger assemblies, while standard SS 316 is used for parts requiring slightly higher strength in the as-formed condition.

Molybdenum Content & Pitting Resistance Equivalent (PREN)

The Pitting Resistance Equivalent Number (PREN) for SS 316 (approximately 24–26) is notably higher than SS 304 (approximately 18), reflecting the molybdenum contribution to localized corrosion resistance. Higher PREN values correlate directly with longer service life in chloride-bearing environments such as seawater and de-icing salt exposure.

Stamping Characteristics of SS 316 vs SS 304

SS 316 has a marginally higher work-hardening rate than SS 304, requiring slightly adjusted press tonnage and die clearance for equivalent stamped features. Both grades exhibit excellent formability suited to deep drawing, bending, and piercing operations common in stamped bracket and hardware production.

Surface Passivation for SS 316 Stamped Parts

Passivation per ASTM A967 removes free iron contamination introduced during stamping and die contact, restoring the full chromium oxide passive layer across cut edges and formed surfaces. This step is essential for SS 316 parts destined for immersion or continuous salt-spray service.

Certification & Traceability for Critical Applications

Heat number traceability from raw coil to finished stamped component, combined with Positive Material Identification (PMI) verification, is available for safety-critical offshore and power utility applications requiring documented grade confirmation at the point of installation.

Manufacturing Process

SS 316/316L coil is blanked and formed on progressive or single-station presses with die clearances and press tonnage adjusted for the grade’s work-hardening characteristics. Formed parts undergo deburring, passivation per ASTM A967, and 100% or batch dimensional inspection. PMI verification using handheld XRF analyzers confirms molybdenum and chromium content for critical orders. Heat number traceability is maintained from raw coil through finished, packed components.
