Stainless steel 201 and stainless steel 304 are different asthe followings:

Different chemical composition: 201 stainless steel inside the carbon structure within 0.15 mg;The carbon structure of 304 stainless steel is less than 0.08 mg.

Different performance: 304 stainless steel than 201 stainless steel is softer, its corrosion resistance is more prominent.

Application range is different: 304 stainless steel is used in the kitchen or bathroom more humid place;The 201 stainless steel is suitable for dry areas or decoration areas.

Compared from the price: because the corrosion resistance of 304 stainless steel is more prominent, so it is made into a slightly more expensive product.
