What are Stainless Steel 410 Nuts?
- SS 410 (UNS S41000 / 1.4006): A hardenable martensitic stainless steel containing 11.5% to 13.5% chromium. It combines high mechanical yield strength, high hardness through heat treatment, and basic corrosion resistance for stress-heavy mechanical assemblies.
- ASTM A194 Grade 6: The high-temperature, high-pressure specification governing UNS S41000 Nuts, ensuring certified tensile performance and tempering stability in valve, pump, and turbine hardware.

Why Industries Prefer SS 410 Series Nuts
Engineers choose UNS S41000 Nuts for high-load, abrasive industrial environments where austenitic stainless steels (like 304 or 316) are too soft and subject to thread galling or surface wear.
Because SS 410 is martensitic, it can be quenched and tempered to significantly elevate yield strength and surface hardness. As a certified SS 410 Nuts Supplier, Aurum Overseas delivers these high-strength fasteners to steam turbine manufacturers, valve producers, and mine equipment builders globally.

SS 410 Heavy Hex Nuts
Key Advantages of UNS S41000 Series Nuts
Heat-Treatable Hardness
Martensitic structure allows thermal hardening to deliver high wear and abrasion resistance on thread surfaces.
High Yield & Tensile Strength
Yield strength starting at 275 MPa (and higher when quenched/tempered), providing superior clamping force under mechanical loads.
Resists Thread Galling
Higher surface hardness prevents friction-welding and thread seizure during high-speed power wrench installation.
Magnetic Characteristics
Naturally magnetic in all heat-treated conditions, aiding magnetic sorting and alignment in automated assembly lines.
Cost-Effective Corrosion Resistance
Provides reliable protection in fresh water, mild steam, and non-aggressive chemical environments without expensive alloying additives.
Key Applications of SS UNS S41000 Series Nuts
Our stainless steel 410 nuts are deployed globally in power generation equipment, pump and valve manufacturing, petroleum refining, and heavy mining machinery assemblies.
| Industry Sector | Primary Fastener Application |
|---|---|
| Power Generation | Steam turbine casings, boiler mountings, and high-pressure steam valve bolting |
| Pump & Valve Manufacturing | Internal trim bolting, gland packing studs, and pump casing assembly fasteners |
| Petroleum Refining | Fractionation column internals and non-sour gas piping flanges |
| Mining & Heavy Machinery | Conveyor hardware, crushing equipment bolts, and vibrating screen fasteners |
| Automotive & Aerospace | High-stress engine brackets and exhaust manifold structural fasteners |
SS 410 Nuts vs SS 304 Nuts
When selecting the ideal stainless fastener grade for your assembly, understanding the structural and performance differentials between SS 410 and SS 304 is crucial.
| Comparison Factor | SS 410 Nuts | SS 304 Nuts |
|---|---|---|
| Microstructure | Martensitic (Hard, high strength) | Austenitic (Ductile, non-magnetic) |
| Heat Treatment | Can be hardened and tempered by heat treatment | Cannot be hardened by heat treatment |
| Hardness & Strength | Significantly higher yield strength and wear resistance | Moderate strength, higher stretch and elongation |
| Corrosion Resistance | Moderate (Best for steam, mild air, and fresh water) | High (Protects against industrial atmosphere and chemicals) |
| Magnetism | Fully Magnetic in all conditions | Non-Magnetic (may become slightly magnetic when cold worked) |
