201 stainless steel and 304 which is better
Generally, there are two materials in the stainless steel factory, 201 stainless steel and 304 stainless steel. Some manufacturers can produce 304 stainless steel, some can produce 201 stainless steel, some manufacturers can produce both kinds of stainless steel profile. But in many consumers serious, unable to distinguish 304 stainless steel and 201 stainless steel, small today and we share the difference between two types of steel!
304 stainless steel
304 stainless steel is the most common material in stainless steel, high temperature resistance, good processing performance, 304 stainless steel is the most important element Ni, CR, is widely used in industry and food medical industry.
201 stainless steel
201 stainless steel has certain acid and alkali resistance, high density, no bubble polishing, no pinhole and other characteristics. The main chemical components are:
Carbon (C) : 0.15 or less
Silicon (Si) : 1.00 or less
(Mn) manganese :5.5 ~ 7.50
(Cr) chromium :16.0 ~ 18.0
Nitrogen (N) : 0.25 or less
Phosphorus (P) : 0.060 or less
Sulfur (S) : 0.030 or less
Nickel (Ni) : 3.5 to 5.5
201 stainless steel is mainly used for decorative pipe, industrial pipe or some less stretched products!
The difference between 304 stainless steel and 201 stainless steel.
1. Different chemical composition
201 chemical composition of stainless steel
Carbon (C) : 0.15 or less
Silicon (Si) : 1.00 or less
(Mn) manganese :5.5 ~ 7.50
(Cr) chromium :16.0 ~ 18.0
Nitrogen (N) : 0.25 or less
Phosphorus (P) : 0.060 or less
Sulfur (S) : 0.030 or less
Nickel (Ni) : 3.5 to 5.5
Chemical composition of 304 stainless steel
C: 0.08 or less
Mn: 2.00 or less
P: 0.045 or less
S: 0.030 or less
Si: 1.00 or less
Cr: 18.0-20.0
Ni: 8.0 to 11.0
The distinction of domestic brand
Stainless steel brand: 1Cr17Mn6Ni5N. 304 stainless steel grade: 06Cr19Ni10(or 0Cr18Ni9).
The performance difference between
The chromium nickel content and carbon content of 304 stainless steel and 201 stainless steel are different. 304 stainless steel is softer than 301 stainless steel, but 304 has better corrosion resistance.
Application range difference
304 stainless steel has good corrosion resistance and high temperature resistance. It can be used in bathrooms, kitchens and coastal moist areas. 201 stainless steel is mainly used for dry areas or decorative areas!
Plating color difference
Vacuum plating compared to water plating effect is better, but both plating color method will first remove the layer of stainless steel protective film, it is recommended to do plating color stainless steel 304 stainless steel material.
