Characteristics and Applications of 904L Stainless Steel
904L stainless steel is a low-carbon high-alloy austenitic stainless steel material. The steel is developed for use in non-oxidizing solutions such as sulfuric acid and is also suitable for use in neutral chlorine-containing (pitting-prone) environments and in environments susceptible to crevice and stress corrosion cracking. 904L is a single phase austenitic stainless steel with good weldability. Due to its high molybdenum content and the specially designed low-impurity-content consumables, the filler metal, although single-phase austenite, prevents hot cracking during the welding process. 904L complies with the following standards: SS2562, DIN1.4539, ASTM N08904 and NFZ1 NCDU25-20. Thermoforming: This material is easy to thermoforming, but care must be taken to keep the thermoforming temperature between 950-1200 °C. Excessive temperature will reduce the forming ability of the steel, and the forming speed in the heating range will be accelerated. If the final mo...
