Request For Our Latest Prices on Stainless Steel 310/310S Nuts in Mumbai, India!
Mumbai-based Fasteners Mart is a renowned manufacturer and worldwide supplier of top-grade industrial fasteners. We are expert providers of strong, high-performance fasteners such as Stainless Steel 310/310S Nuts, which have superior heat and corrosion resistance. These nuts, manufactured using Grade 310 and 310S austenitic stainless steel, come in multiple shapes like hex, square, and heavy-duty nuts. Their nickel and chromium content ensures high performance at severe temperatures, and thus they find great use in furnace and high-temperature structural applications.
Stainless Steel 310/310S Nuts consist of iron, chromium (24–26%), and nickel (19–22%), with 310S having lower carbon to prevent carbide precipitation in welding. Their mechanical behavior is tensile strength of approximately 520 MPa, yield strength of 205 MPa, and elongation of 40%. They are physically dense at 7.9 g/cm³ and have a melting point of between 1400–1455°C. These properties offer excellent high-temperature oxidation resistance and strength, suited to applications involving thermal cycling and corrosive environments.
