The differences between 201, 304, 316, and 400 stainless steel are: different structures, different magnetic properties, and different advantages.
1. Different structure
201 stainless steel is the general name of 201 stainless steel and acid-resistant steel. The main structural components are chromium, manganese and nickel.
304 stainless steel, also known as 18/8 stainless steel in the industry, is a chromium and nickel stainless steel.
316 stainless steel incorporates metal molybdenum, which consolidates the molecular structure of stainless steel.
400 stainless steel is martensitic stainless steel.
2. Different magnetic
201, 306, and 316 stainless steels are not magnetic, while 400 stainless steel is magnetic.
3. Different advantages
201 is acid-resistant steel, which refers to steel that is resistant to corrosion by chemically corrosive media such as acid, alkali, and salt.
304 stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening.
316 stainless steel is based on 304 and has stronger heat resistance.
The 400 series stainless steel can be hardened by heat treatment and can be used to make stainless steel tableware.
