Leave a message
What is AISI 201?
AISI-201 is an austenitic chromium nickel-manganese stainless steel that was developed originally to conserve nickel. It provides properties similar to AISI-301 and can be used in most applications for AISI-301. This alloy is nonmagnetic in the annealed condition but becomes slightly magnetic when cold worked.
What is 1.4372 material equivalent to?
What is the equivalent of 1.4372 stainless steel? Stainless steel grade EN 1.4372 is equivalent to AISI 201. It is also known by other names such as UNS S20100 and is a chromium-nickel-manganese austenitic stainless steel.
Is 201 stainless steel good quality?
Yes, 201 stainless steel is suitable for many applications, especially when cost is an important factor. It is an economical alternative to 304/316 stainless steel, offering good strength, formability, and decent corrosion resistance for indoor or mild environments, such as in kitchenware, appliances, and decorative items.

What is the difference between stainless steel 304 and 201?
Stainless steel 201 is a cheaper, lower-nickel option with good strength for indoor/budget use, while 304 is the premium choice with higher chromium and nickel, offering superior corrosion resistance, making it ideal for kitchenware, food-grade items, and harsh environments, despite its higher cost. The key difference lies in their composition: 304 has more nickel (8-10.5%) and chromium (18-20%), whereas 201 has less nickel (1-3%) and more manganese (5.5-7.5%), making 304 more durable and resistant to rust
What is the difference between nickel 200 and 201?
Nickel 200 vs. 201 is about carbon content: Nickel 200 (0.15% max C) is great for below 315°C (600°F), while Nickel 201 (0.02% max C) is the low-carbon version, preventing high-temp embrittlement (graphitization) above 315°C (600°F) up to 1250°F, making it better for high-heat applications like chemical processing, while both offer excellent corrosion resistance, especially to alkalis.
What is the difference between 201 and 316 stainless steel?
201 is a budget-friendly, lower-nickel option with moderate strength and lower corrosion resistance, using manganese for cost savings, while 316 is premium, containing molybdenum for superior resistance to chlorides and marine environments
