1.4372 vs 1.4301 stainless steel: Key differences
Leave a message
What is EN 1.4372 material?
EN 1.4372 is an austenitic stainless steel, also known as grade 201 or X12CrMnNiN17-7-5, often used as an economical alternative to 304 in structural applications. It is made with a higher manganese content and a lower nickel content to conserve nickel while maintaining good strength, ductility, and weldability. Its properties include moderate corrosion resistance and good mechanical properties.
What is EN 1.4301 stainless steel?
EN 1.4301 is an austenitic chromium-nickel stainless steel, also known as AISI 304 or X5CrNi18-10. It is a versatile and high-performance material with excellent corrosion resistance, good weldability, and a wide range of industrial applications. It is commonly used in kitchen sinks, cookware, food and dairy equipment, and building materials.
What is the difference between 1.4372 and 1.4301 stainless steel?
The main difference is that 1.4301 (AISI 304) is a chromium-nickel stainless steel with excellent corrosion resistance and formability, while 1.4372 (AISI 201) is a chromium-manganese-nickel stainless steel with higher manganese and lower nickel content. This makes 1.4372 have higher strength and work hardening, but potentially slightly lower corrosion resistance compared to 1.4301.

Which stainless steel is more corrosion resistant: 1.4372 or 1.4301?
1.4301 stainless steel is more corrosion resistant than 1.4372. 1.4301 is a standard chromium-nickel steel with excellent corrosion resistance in most environments, while 1.4372 is a chromium-manganese grade with slightly lower corrosion resistance, though still good for many applications.
When to use 1.4372 stainless steel instead of 1.4301?
Use 1.4372 stainless steel (AISI 201) instead of 1.4301 (AISI 304) when you need higher strength, particularly in the cold-worked or temper-rolled condition, due to its higher work hardening rate. It is a cost-effective alternative that uses higher manganese content to reduce nickel, making it suitable for applications like cookware, transportation, and architectural components.
Stainless steel sheets 201LN vs 304
The main differences are cost, corrosion resistance, and hardness, with 304 offering superior corrosion resistance due to its higher nickel content, making it better for harsh environments and long-term durability. In contrast, 201LN is a more budget-friendly option with higher strength and hardness but lower corrosion resistance, making it suitable for indoor or less demanding applications.
Which is better 1.4301 or 1.4307?
1.4307 (304L) is better for applications involving welding or where long-term corrosion resistance in the heat-affected zone is crucial, due to its lower carbon content. 1.4301 (304) is a suitable, slightly stronger, and more cost-effective option for general use in milder environments where welding is not extensive.
1.4372 vs 1.4301 stainless steel Price per kg
The current market price for EN 1.4372 stainless steel (AISI 201) is approximately USD 1.00–1.50/kg, while the price for 1.4301 (304) stainless steel is around USD 2.50–4.00/kg (depending on pipe thickness). This price difference is mainly due to the lower nickel content in the 201 grade, making it more cost-effective.
