Stainless Steel Hot Rolled Plate
Stainless steel hot rolled plates are available in a wide range of grades, including austenitic, フェライト系, マルテンサイト系, デュプレックス, and high-alloy stainless steels. The most commonly used grades are 304, 316L, 430, 410, 420, そして 2205, depending on corrosion resistance, 強さ, および申請要件. Hot rolled plates are widely used in industrial and structural fields where strength and durability are more important than surface finish precision.
- 説明
Stainless steel hot rolled plate is produced by rolling stainless steel at high temperatures above the recrystallization point. This process allows the material to be formed in thicker dimensions and provides good mechanical strength, making it widely used in structural, 工業用, and heavy-duty applications.
Compared with cold rolled sheets, hot rolled stainless steel plates are typically thicker, have a slightly rougher surface finish, and are more suitable for fabrication and engineering use.
Common Grades of Stainless Steel Hot Rolled Plate
Stainless steel hot rolled plates are available in a wide range of grades depending on corrosion resistance, 強さ, および申請要件.
