Material: Stainless Steel – Strength Meets Corrosion Resistance
Overview:
Stainless steel is one of the most reliable and durable materials used in fastener manufacturing. Known for its high corrosion resistance, clean appearance, and mechanical strength, stainless steel fasteners are ideal for applications where exposure to moisture, chemicals, or extreme temperatures is common.
At SM Fasteners, we use premium-grade stainless steel, primarily SS 304, SS 316, and other variants like SS 410 and SS 202, to manufacture a wide range of bolts, nuts, studs, washers, and customized components.
Why Stainless Steel?
Stainless steel fasteners offer a superior combination of mechanical performance and chemical resistance. The chromium content (minimum 10.5%) forms a passive oxide layer, which protects the surface from rust—even in highly corrosive or saline environments.
✅ Rust & Corrosion Resistance
✅ No Surface Coating Needed
✅ Non-Magnetic Grades Available
✅ High Strength-to-Weight Ratio
✅ Aesthetic & Hygienic Finish
✅ Sustainable & 100% Recyclable
Common Grades of Stainless Steel We Offer:
| Grade | Composition | Properties | Applications |
|---|---|---|---|
| SS 304 | 18% Cr, 8% Ni | General-purpose corrosion resistance, non-magnetic, food-safe | HVAC, Food Processing, Architecture |
| SS 316 | 16% Cr, 10% Ni, 2% Mo | Superior resistance to marine, acidic, and chloride-rich environments | Marine Equipment, Chemical Plants |
| SS 202 | 17% Cr, 4% Ni, Mn-based | Cost-effective alternative, decent corrosion resistance | Domestic Fittings, Automotive |
| SS 410 | 11.5–13.5% Cr | High hardness and wear resistance, magnetic | Pump Shafts, Industrial Tools |
Applications of Stainless Steel Fasteners:
Marine and Shipbuilding
Water Treatment Plants
Food & Beverage Processing Machinery
Pharmaceuticals and Medical Equipment
Chemical and Petrochemical Plants
Construction and Façade Cladding
Renewable Energy (Solar, Wind Structures)
Finishing & Surface Treatment
Although stainless steel does not require coating, we offer various post-processes for enhanced performance:
Passivation – To remove surface contaminants and improve corrosion resistance
Electropolishing – For ultra-smooth, bright finish
Pickling – To remove weld scale or discoloration
Glass Bead Blasting – For matte or satin appearance
Teflon/PTFE Coating – For anti-galling and low friction
Certifications & Documentation
Every stainless steel batch is traceable and supported by:
Material Test Certificates (EN 10204 Type 3.1/3.2)
PMI (Positive Material Identification) Reports
Hardness and Tensile Strength Reports
Surface Roughness and Salt Spray Test Results (if applicable)
