In depth analysis of 201 stainless steel: fully aware of its performance advantages and usage scenarios

Its characteristics are good acid and alkali resistance, but its corrosion resistance is slightly inferior to 304 and 316 stainless steel

 

What are the basic characteristics of 201 stainless steel?
201 stainless steel is a type of martensitic stainless steel, mainly composed of chromium (13% -15%) and nickel (3% -5%), with a sulfur content of ≤ 0.030. Its corrosion resistance is suitable for weak medium environments such as atmosphere, steam, and water, but it shows weaker performance in strong acid, strong alkali, or high salt environments. ‌‌

 

Main purpose
Decoration and industrial fields: such as decorative pipes, industrial pipes, and shallow stretch products. ‌‌
Daily necessities: Some tableware, kitchen equipment, and other scenarios that do not require high corrosion resistance. ‌‌

 

Property	201 Stainless Steel	304 Stainless Steel	316 Stainless Steel
Chromium Content	13%-15%	18%-20%	16%-18%
Nickel Content	3%-5%	8%-10%	10%-14%
Corrosion Resistance	Weak (prone to rust)	Strong (daily corrosion resistance)	Extremely strong (resistant to strong acids and marine environments)
Price	Lower	Moderate	Higher

 

 

Is 201 stainless steel suitable for cooking utensils?
Suitable, but its corrosion resistance is not as good as 304 or 316, so it is more prone to rusting and discoloration

 

Will 201 stainless steel turn green?
Generally speaking, stainless steel does not turn green because it contains a high proportion of chromium. Chromium plays a crucial role in stainless steel
