What’s The Difference Of 201, 201 J1, 201 J2, 201 J3, 201 J4?

201 Stainless Steel
Copper content: J4>J1>J3>J2>J5.
Carbon content: J5>J2>J3>J1>J4.
Hardness arrangement: J5, J2>J3>J1>J4.
The order of prices from high to low is: J4>J1>J3>J2, J5.
J1(Mid Copper): The carbon content is slightly higher than J4 and the copper content is lower than J4. Its processing performance is less thanJ4. It is suitable for ordinary shallow drawing and deep drawing products, such as decorative board, sanitary products, sink,product tube, etc.

J2, J5:Decorative tubes: Simple decorative tubes are still good, because the hardness is high (both above 96°) and the polishing is morebeautiful, but the square tube or the curved tube (90°) is prone to bursting.
In terms of flat plate: due to the high hardness, the board surface is beautiful, and the surface treatment such as
frosting,polishing and plating is acceptable. But the biggest problem is the bending problem, the bend is easy to break, and the groove is easy to burst. Poor extensibility.

J3(Low Copper): Suitable for decorative tubes. Simple processing can be done on the decorative panel, but it is not possible with a little difficulty. There is feedback that the shearing plate is bent, and there is an inner seam after breaking (black titanium,color plate series, sanding plate, broken, folded out with inner seam). The sink material has been tried to bend, 90 degrees, but it will not continue.

J4( High Copper): It is the higher end of the J series. It is suitable for small angle types of deep drawing products. Most of the products that require deep salt picking and salt spray test will choose it. For example, sinks, kitchen utensils, bathroom products, water bottles, vacuum flasks, door hinges, shackles, etc.
