Daxun stocks 201 stainless steel plates (hot rolled and cold rolled). Because a portion of the nickel used in 300 series stainless steels (such as Type 304) is replaced with manganese, the 201 grade alloy is generally a high performance, lower cost, more stable austenitic stainless steel. In addition, the chemical composition of the 201 stainless steel provides better annealed mechanical properties than Type 304, which may provide further advantages in terms of weight reduction. Because the tensile strength of Type 201 is approximately 10% higher than that of Type 304, thinner gauges can be used, using less material overall. However, Type 201 stainless steel has lower chromium and nickel contents, so it is not as corrosion resistant as Type 304. 201 grade stainless steel is frequently used in domestic and commercial food service applications, construction applications, appliances, and other uses.
Corrosion Resistance: 201 stainless steel plate has excellent corrosion resistance suitable for both indoor and outdoor applications. Its excellent corrosion resistance. Stainless steel sheet has excellent resistance to atmospheric conditions, moisture and specific chemicals, thus guaranteeing long-lasting performance and durability. By providing excellent resistance to atmospheric conditions, moisture and specific chemicals, it guarantees long-lasting performance and durability.
High Strength: 201 stainless steel plate is able to withstand heavy weight and pressure due to its high tensile strength. Steel sheet is able to withstand large mass and pressure due to its high tensile strength. Parts and structural components that require extreme durability.
Steel sheet is a beautiful material that can add a touch of elegance to any project due to its smooth, polished surface. It is suitable for architectural elements, kitchen utensils and decorative applications due to its easy-to-clean and shiny surface. It is perfect for architectural elements, kitchen utensils and decorative applications due to its easy-to-clean and shiny surface.
It is a cost-effective solution compared to other grades of stainless steel without sacrificing quality. It is favored by budget-constrained projects due to its reliable performance and reasonable price. It is the choice of budget-constrained projects due to its reliable performance and reasonable price.
