201/ J4 Square Tube Welded Tube BA 14 Gauge Factory Wholesale SS201 J4 Tube
Judging from the plates, 202 has one more manganese and three more nickels than 201. In practical application, 202 is slightly better than 201 in terms of utility, but most market users accept the 201 material decorative tube with lower price and similar actual utility as 202. 202 has slightly more chromium and manganese than 201, and its mechanical and corrosion resistance are also slightly better. But strictly speaking, the performance of these two kinds of stainless steel is not very different in nature, especially in the corrosion resistance.
