Which is better, 304 stainless steel or 201 stainless steel? What's the difference?
Which is better, 304 stainless steel or 201 stainless steel? What's the difference?
Generally, there are two kinds of materials in stainless steel manufacturers, 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 profiles. But in the serious situation of many consumers, it is impossible to distinguish 304 stainless steel and 201 stainless steel. Today, I would like to share with you the difference between the two types of steel!
304 stainless steel
304 stainless steel is the most common material in stainless steel, with high temperature resistance and good processing performance. The most important elements of 304 stainless steel are Ni and Cr, which are widely used in industry and food and medical industry.
201 stainless steel
201 stainless steel has the characteristics of acid and alkali resistance, high density, no bubble and no pinhole in polishing. The main chemical components are as follows:
(C) Carbon: ≤ 0.15
(SI) Si: ≤ 1.00
(MN) Mn: 5.5-7.50
(CR) Cr: 16.0-18.0
(N) Nitrogen: ≤ 0.25
(P) Phosphorus: ≤ 0.060
(S) Sulfur: ≤ 0.030
(Ni) Ni: 3.5-5.5
201 stainless steel is mainly used for decorative pipe, industrial pipe or some under stretched products!
The difference between 304 stainless steel and 201 stainless steel.
1. The chemical composition is different
Chemical composition of 201 stainless steel
(C) Carbon: ≤ 0.15
(SI) Si: ≤ 1.00
(MN) Mn: 5.5-7.50
(CR) Cr: 16.0-18.0
(N) Nitrogen: ≤ 0.25
(P) Phosphorus: ≤ 0.060
(S) Sulfur: ≤ 0.030
(Ni) Ni: 3.5-5.5
Chemical composition of 304 stainless steel
C:≤0.08
Mn：≤2.00
P：≤0.045
S：≤0.030
Si：≤1.00
Cr：18.0–20.0
Ni：8.0-11.0
Difference of domestic brands
Grade of 201 stainless steel: 1Cr17Mn6Ni5N. Grade of 304 stainless steel: 06cr19ni10 (or 0Cr18Ni9).
Performance differences
304 stainless steel is softer than 301 stainless steel, but its corrosion resistance is better.
Application scope difference
304 stainless steel has good corrosion resistance and high temperature resistance, which can be used in bathroom, kitchen and coastal wet area; 201 stainless steel is mainly used in dry area or decoration field!
Color difference
Vacuum plating is better than water plating, but both methods will remove the protective film of stainless steel first. It is recommended to use 304 stainless steel for color stainless steel tube.
From belyoo factory all stainless steel is 304 or 316 stainless steel accord with food industry quality demand.we know the difference so we choose the best!
Well, that's the difference between 304 stainless steel and 201 stainless steel. Are you clear?
