SS 202 シート
SS 202 stainless steel sheet is a cost-effective austenitic stainless steel with good strength, 成形性, and acceptable corrosion resistance for general use.
その lower nickel content and higher manganese composition make it more affordable than 304, while still maintaining reliable performance in indoor, 装飾的な, and light industrial applications.
- 説明
202 stainless steel sheet is an オーステナイト系ステンレス鋼 belonging to the Cr–Mn–Ni series. It is developed as a cost-effective alternative to 300-series stainless steels, 特に 304, by partially replacing nickel with manganese and nitrogen.
It offers a good balance of 強さ, 成形性, 適度な耐食性, making it suitable for many general-purpose applications.
