Stainless Steel 310 Bolts are intended for high temperature and high pressure services. The specification for these bolts is ASTM A193. There are different lengths ranging from 3mm to 200mm and different sizes ranging from M3 through M56 and 3/6 inches to 2 inches with custom sizes available as well. The Stainless Steel 310 Bolts can vary in types and shapes such as the hex head bolts, square bolts, U bolts, eye bolts, t bolts and so on. They are all used in different applications for different fitting purposes.
Rajat Steel is a leading supplier and manufacturer of these bolts in all dimensions and scales. The material of the Alloy 310 Hex Bolt and others is a chromium nickel alloy with 24% chromium and 19% nickel with carbon, manganese, silicon, phosphorus and sulfur in it. The different types are useful in serving different purposes. The SS 310 Studs are used to fit two threaded components together as the studs have threads on both ends. The strength of the material is comparable to the 304 grade of the stainless steel. The material has 205MPa minimum yield strength and 515MPa minimum tensile strength.
The hardness of the ASTM A193 310 Stainless Steel Nuts is 217 HB in the Brinell hardness scale. The composition, mechanical properties and the physical properties of the Stainless Steel 310 Fasteners make them applicable for high temperature, high pressure services such as heat exchangers, condensers, pulp and paper industry, pharmaceuticals, petrochemicals and many others. Please contact us for more information on the different types of the bolts such as the SS UNS S31000 Stainless Steel U-bolts and others with their prices.
