The Fasteners Mart, Mumbai, India, is a leading supplier of high-quality fasteners and industrial parts to different industries like construction, automotive, aerospace, and manufacturing. The company is dedicated to providing dependable products, such as Stainless Steel 317/317L nuts, which are produced from austenitic stainless steel alloys. The nuts are produced in grades 317 and 317L, providing superior corrosion resistance, high strength, and durability. The nuts are of various shapes like hexagonal, square, and as per custom, and hence are used for applications in high temperature and corrosive conditions.
Stainless Steel 317/317L nuts are austenitic alloys consisting of 18-20% chromium, 3-4% molybdenum, and 10-12% nickel. Grade 317 has more molybdenum content for greater corrosion resistance than 304 stainless steel. Grade 317L has reduced carbon content with improved weldability. They have tensile strength of 500 MPa to 700 MPa, yield strength of approximately 250 MPa, and high resistance to pitting, crevice corrosion, and stress corrosion cracking. They also have good mechanical properties at high temperatures.
