SUS304J1 is developed byJapanon the basis of AISI304 stainless steel. 304J1 is a stainless steel that reduces nickel and increases copper on the basis of 304 stainless steel. Due to the addition of copper, the deformation resistance of 304 stainless steel is improved, and the cracking of products caused by significant hardening and high residual stress during or after cold working is improved, so it has good tensile forming performance and is suitable for deep processing products.
304J1 stainless steel performance is close to 304 stainless steel, the price is cheaper, is a good substitute for low-end use of 304 stainless steel, widely used in the field of daily life。
