Detailed Information

Prashaant Steel & Alloys is a well-known ASTM F593 Fasteners maker and retailer. We manufacture ASTM F593 Fasteners with the best quality raw materials from our vast inventory. Prashaant Steel & Alloys produces ASTM F593 Fasteners of excellent quality and has carved out a niche for itself in the industry. Our ASTM F593 Fasteners are highly common and are used in a number of industries due to their high strength and reliability. Prashaant Steel & Alloys has a well-equipped production facility that can fill huge orders of ASTM F593 Fasteners in a range of sizes and diameters. We manufacture ASTM F593 Fasteners and export them to all of the world’s big cities. We store our goods in suitable wooden boxes and ship them with all appropriate paperwork to prevent product degradation during shipping.

The ASTM F593 Nut Bolt in group1 can be made up of the 303, 304, 305, 384 austenitic stainless steels. The 316 austenitic stainless fasteners belong to the alloy group 2 and 321 347 grades belong to the alloy group 3. The ASTM F593 18-8 Stud can be made of ferritic alloys in group 4, martensitic alloys of groups 5 and 6 or with precipitation hardening alloys of group 7. The ASTM F593 Stainless Steel Threaded Rod and other fasteners have varying strength values based on the different material grade. The chemical composition of the materials include carbon, manganese, phosphorus, sulfur, silicon and chromium. The minimum tensile strength ranges from 65ksi to 150 ksi and the minimum yield strength ranges from 20ksi to 65ksi. The hardness of the ASTM F593 cw Nuts ranges up to B95. 

ASTM F593 Bolts range from ¼ inches to 1 ½ inches in diameter. The specification covers stainless steel bolts, studs and cap screws in this diameter range. There are different materials used to produce these fasteners. There are 8 groups of alloys that are used and based on the group the material grade differs.
