Strong in low-temperature strength and toughness! Welding materials with a large coefficient of expansion and low thermal conductivity.
"Austenitic stainless steel" has excellent workability and weldability, and unlike other stainless steels, it is a non-magnetic welding material. Due to its sensitivity to stress corrosion cracking, care must be taken regarding stress concentration in welded areas. Additionally, craters are prone to cracking, so it is necessary to devise welding techniques such as crater treatment. In vacuum device components, having magnetic properties can be problematic, making this material optimal. 【Features】 - High coefficient of expansion and low thermal conductivity - Better weldability compared to martensitic, ferritic, and duplex stainless steels - SUS304 series has good weldability - Susceptibility to weld cracking is higher in materials with high nickel and molybdenum content, making them sensitive to hot cracking - Strong low-temperature strength and toughness For more details, please contact us.
