317 Stainless Steel Fasteners are made up of a chromium nickel alloy that has higher amounts of chromium and nickel than the 316 material. There are bolts, nuts, washers and other fasteners that belong to this grade of stainless steel. The Stainless Steel 317 Nuts have 19% chromium, 13% nickel, carbon, manganese, silicon, phosphorus and sulfur in the composition.
317 Stainless Steel Fasteners
317L Stainless Steel Bolts
ASTM A479 317L SS Stud Bolt
The material has higher strength than the 316 material as well. The minimum yield strength is 275MPa and the minimum tensile strength is 620MPa with 45% elongation and 193HB max hardness. There are different types of fasteners such as the SS 317L Socket Cap Screw which is used for applications that need to the use of heavy tools and high torque strength. The fasteners belong to ASTM A193 and 194 standards. The length of the fasteners range from 3mm to 200mm. The Stainless Steel 317 Bolts are strong however, they are not very efficient against chloride ion rich environments because they lack molybdenum in the composition unlike the 316 material. The nuts sizes range from M3 to M56 and the screw sizes range the same as well. The machines screws range from M1.6 through M12. The 317 SS Stud Bolt can range from 3/6 inches to 2 inches. The application of these fasteners can be seen in a variety of application such as domestic and general corrosive applications, engineering applications, automobile and other applications as well. The SS 317L Screws can come with coarse threads or fine threads with different types of head such as hex head and others.
