SS 310H Fasteners Supplier & Exporter for Global Industrial Markets
Aurum Overseas is a trusted SS 310H fasteners supplier and exporter providing heat-resistant stainless steel fastening solutions for refinery heaters, pressure vessels, thermal reactors, and high-temperature processing systems. SS 310H is selected where elevated-temperature strength, oxidation resistance, creep resistance, and long-term thermal stability are essential.
Refinery and thermal processing equipment operates under continuous heat, combustion gases, thermal cycling, and pressure fluctuations. SS 310H fasteners help maintain structural reliability under these demanding conditions and are widely used by EPC contractors, refinery operators, and industrial manufacturers across international markets.
High Carbon Chromium-Nickel Metallurgy and Mechanical Properties of SS 310H Fasteners
SS 310H combines a high chromium-nickel austenitic structure with controlled higher carbon content for improved creep resistance and strength at elevated temperatures.
Chemical Composition of SS 310H Fasteners
| Element | Composition (%) | Functional Role |
|---|---|---|
| Chromium | 24 – 26 | Oxidation resistance |
| Nickel | 19 – 22 | Elevated temperature stability |
| Carbon | 0.04 – 0.10 | Creep strength enhancement |
| Manganese | 2.0 max | Structural balance |
| Iron | Balance | Mechanical structure |
Mechanical Properties of SS 310H Fasteners
| Property | Value |
|---|---|
| Tensile Strength | 515 – 750 MPa |
| Yield Strength | 205 – 310 MPa |
| Elongation | 35 – 45% |
| Hardness | 95 HRB max |
The combination of elevated-temperature strength and oxidation resistance supports reliable fastening performance in continuous high-temperature industrial service.
Resistance to Oxidation, Scaling and Creep Deformation at Elevated Temperatures
SS 310H fasteners provide strong resistance to oxidation and scaling during continuous exposure to elevated temperatures and combustion gases. Their high chromium content supports formation of a protective oxide layer, helping reduce surface degradation in refinery heaters, furnaces, and thermal processing equipment.
The higher carbon content also supports creep resistance during prolonged thermal loading, helping maintain dimensional and mechanical stability where standard stainless steel fasteners may experience deformation. This makes SS 310H suitable for pressure systems, thermal reactors, and high-temperature industrial assemblies.
SS 310H also performs in carburizing atmospheres and cyclic heating conditions where repeated expansion and contraction can contribute to thermal fatigue. These properties support applications in refinery combustion systems, thermal processing infrastructure, and high-temperature pressure equipment.
ASTM, ASME and Refinery Pressure Equipment Standards for SS 310H Fasteners
SS 310H fasteners supplied by Aurum Overseas are manufactured and inspected according to applicable international standards for refinery, pressure equipment, and thermal engineering applications.
