In the world of metallurgy, stainless steel is one of the most versatile and durable materials. Among the various types of stainless steel, 201 stainless steel has attracted much attention for its unique combination of properties and cost-effectiveness. Known for its excellent corrosion resistance, high tensile strength, and impressive formability, 201 stainless steel is a popular choice for a wide range of applications, from kitchenware to industrial equipment. In this article, we will take a closer look at the other side of 201 stainless steel.
Other Series of 201 Stainless Steel
201 has no national standard. Domestic 201 stainless steel is divided into five types: J1, J2, J3, J4, and J5 due to different compositions and application fields. The nickel content of these 201 is around 1%. The biggest difference is the copper content and carbon content. The copper content is J4>J1>J3>J2>J5 from high to low, and the carbon content is J5>J2>J3>J1>J4 from high to low. The price is J5>J2>J3>J1>J4 from high to low.
Is 201 Stainless Steel Resistant to High Temperatures?
201 stainless steel is not considered high-temperature-resistant stainless steel. The high-temperature resistance of 201 stainless steel is below 315℃. If the temperature exceeds this, heavy metals will precipitate in the material, and creep and material deformation will occur. Therefore, stainless steel needs to be used at the corresponding temperature, and special high-temperature resistant stainless steel is required in high-temperature environments.
Can 201 Stainless Steel Increase its Hardness?
201 stainless steel belongs to austenitic stainless steel. The structure of austenitic stainless steel is the austenite phase. It will not change phase when heated, so its hardness cannot be increased by conventional heat treatment methods. The hardness of austenitic stainless steel mainly depends on its chemical composition and cold working treatment method. Through cold working such as cold rolling and cold drawing, cold drawing can deform the grains of stainless steel, thereby increasing its hardness. However, the hardness increased by this method is also limited, and it will have a certain impact on the plasticity and toughness of stainless steel.
Can 201 Stainless Steel be Stretched?
It depends on whether 201 J1, J2, or J4 is used. The factors that affect the stretching of 201 stainless steel are mainly the copper content. The lowest copper content is J2, which contains 0.3% copper and is a low-copper material. It is not suitable for stretching and is only suitable for products with large-angle bending. J1 contains 0.8% copper and is a semi-copper material. It is suitable for large-angle ordinary shallow stretching products. J4 contains 1.5% copper and is a high-copper material. It is the best material in the 201J series and is suitable for deep stretching and small-angle products.
