DC Engineering offers a wide selection of Martensitic Stainless Steel 904L Fasteners, including both supply and production. They are also compatible with the standards set forth by ASTM A193, DIN, and ASTM BS.
Specification of ASTM A193 SS 904L Screws
There are many different types of bolts and nuts, including those with hex heads, panel nuts, tee bolts, dome nuts, and many others. Nickel chromium molybdenum alloy bolt nuts grade 904L are composed of carbon, manganese, silicon, phosphorus, sulfur, and nitrogen. The material exceeds the strength of standard 304 stainless steel. Bolts made from UNS N08904 stainless steel have a tensile strength of at least 490MPa and a yield strength of at least 220MPa. Washers are another type of fastener. Washers made from ASME SA193 904L stainless steel are used to separate bolt heads and nuts, or any other two parts. Washers serve as a stress absorber and gap filler, ensuring that no movement occurs due to expansion. Bolt nuts and studs made of 904L stainless steel have a lower carbon content. This facilitates its use in welding processes. It's also a cheap and easily machined material.
Applications ASTM A193 SS 904L Screws
The austenitic stainless steel 904L has a high chromium, nickel, molybdenum, and copper content and a low carbon content. It is well-known for its high resistance to corrosion, even in harsh environments like salt water and acid. There are threads on both ends of a stud bolt, making it a rod. Flanges, valves, and other devices that require a bolting connection are common places to find it in use. To fasten two parts together, stud bolts and nuts are frequently used. 904L stainless steel stud bolts, in comparison to regular stainless steel stud bolts, have superior corrosion resistance. Regular stainless steels can corrode or experience pitting, so using 904L stainless steel stud bolts is especially helpful in environments with high chloride concentrations, such as marine or coastal applications.
