SUS304J1 is Japanese JIS standard section nickel stainless steel, there is no comparison in China.304J1 is a kind of steel with reduced nickel and copper on the basis of grade 304.The addition of copper reduces the deformation [SCALE STEEL]resistance of the material, so the steel has good performance of deep drawing.

The performance characteristics of：
(1) More excellent forming [SCALE STEEL]performance than 304 steel, suitable for complex forming and deep processing.
(2) Good aging cracking resistance.
(3) The corrosion resistance is basically equal to that of 304.
(4) Excellent welding performance.
(5) Cold rolled product surface gloss is good, beautiful.
(6) Excellent antibacterial performance, suitable for the occasion of strict hygiene requirements.
(7) The solution state is not magnetic, after cold processing will be slightly magnetic.
304 j1 as section 304 of the nickel steel grade, the performance is close to 304, at the same time have a lower cost and[SCALE STEEL] forming ability is more outstanding advantages, so it is relatively low-end USES a good substitute for 304, its wide application in the field of daily life, such as vacuum flask, lunch box, stove, sink, collective to provide facilities, kitchen burning gas, and other household items, etc.
