What is 201 Stainless Steel?

201 stainless steel is an austenitic chromium-nickel-manganese alloy designed as a cost-effective alternative to 304 stainless steel. It contains lower nickel content, replaced partially by manganese and nitrogen, making it more affordable while maintaining good strength and corrosion resistance. This grade is particularly resistant to general atmospheric corrosion and offers excellent toughness at low temperatures.

201 stainless steel is commonly used in applications where cost is a factor, but moderate corrosion resistance and mechanical properties are still required. Typical uses include kitchen utensils, appliance components, automotive trim, and decorative applications. While it performs well in mildly corrosive environments, its resistance to pitting and crevice corrosion is lower than that of 304 or 316 grades, particularly in chloride-rich conditions.

Although it is less expensive, 201 stainless steel still provides good performance in many non-critical applications, making it a popular choice in industries seeking a balance between cost and functionality.

201 Stainless Steel Chemical Composition

201 Stainless Steel Mechanical Properties

Tensile Strength: Generally between 450MPa-650MPa. Higher tensile strength so that it can withstand greater tension without breaking.

Yield strength: generally between 200MPa-300MPa. 201 stainless steel’s yield strength indicates that it will yield and deform under a certain external force, but still can maintain a certain bearing capacity.

Elongation: generally between 30%-55%. Good elongation means that the stainless steel has good plasticity and toughness.

Hardness: usually between HB180-HB253. 201 Stainless Steel’s hardness gives it a certain degree of wear resistance and resistance to deformation. It is suitable for some applications where surface hardness is required. However, its hardness is relatively low compared to some high hardness alloy steels.
