Stainless Steel 310H fasteners are high temperature resistant fasteners made of the austenitic chromium-nickel stainless steel grade of high carbon content. SS 310H fasteners have outstanding resistance to oxidation and excellent high-temperature strength and corrosion resistant properties. Stainless Steel S31009 Fasteners find their application in heat treatment plants, petrochemical plants, power generation, refineries, furnaces and the rest of the industries having high-temperature requirements. Common products include Stainless Steel 310H Hex Bolts, nuts, washers, stud bolts, socket head cap screws and threaded rods produced to ASTM and ASME standards.
Stainless Steel 310H Fasteners Manufacturer, Supplier & Exporter
We are a leading Stainless Steel 310H Fasteners Manufacturer, supplier, and exporter in India, offering superior quality fasteners for aggressive working applications. We hold an abundant stock of Stainless Steel 310H Hex Bolts, screws, nuts, washers, threaded rods, stud bolts, socket screws, and tailor-made fastening elements in ASTM, ASME, DIN and ISO standards.
SS 310H fasteners exhibit excellent resistance to oxidation and scaling at high temperatures, therefore commonly used in all critical industries which require elevated temperature performance. A greater amount of carbon content (0.25%) present in grade 310H increases its creep strength and improves its mechanical characteristics in higher temperatures, making it the most favored material in various thermal and heat-processing machinery.
All of our 310H Stainless Steel Fastener products are manufactured using rigorous quality controls for the purpose of ensuring dimensional correctness, strength and long-term efficiency.
What are Stainless Steel 310H Fasteners?
Stainless Steel 310H Fasteners are industrial fastening components manufactured from high-carbon stainless steel grade 310H, designated as UNS S31009 and commonly referenced under DIN 1.4841 / 1.4845 Heat Resistant Fasteners specifications.
The alloy contains high chromium and nickel content, providing:
- Remarkable resistance to oxidation even in high temperatures
- Superior heat resistance
- Outstanding corrosion resistance
- High creep strength
- Good mechanical strength under thermal stress
- Excellent fabrication and welding characteristics
The beneficial properties of SUS 310H fasteners allow them to be utilized in high-temperature, oxidizing, and corrosive environments.
Key Features of SS 310H Fasteners
- High temperature resistance: High temperature resistance is a key benefit of SS 310H fasteners as they are robust under high temperature applications.
- Good resistance to oxidation: Due to high chromium percentage they create a tough, scaled, and oxidized layer, making them resist scaling and oxidation.
- High creep strength: Compared to basic 310 grade stainless steel, stainless steel 310H grade has a higher carbon percentage which has the capacity of retaining strength at higher temperatures over a prolonged period.
- Corrosion resistance: Stainless Steel S31009 Fasteners have good resistance to industrial chemicals and mild acids, and atmospheric corrosion.
