The 201# made from nickel, chromium and manganese. It’s estimated to be 30 percent stronger than 304, but it’s more difficult to form and weld compared to 304. Furthermore, 304 is corrosion-resistant and can be used in just about any application, whereas 201 has limited versatility.
|cutting disc testing|
OD = 20MM Stainless steel 304# - after 3 cuts the discs rest diameter is 122.5mm
OD = 20MM Stainless steel 201# - after 3 cuts the discs rest diameter is 121.8mm
Reasonable testing data and just proved 201# more stronger than 304# .......
