GBT 25CrMnSi - Special Alloy
25CrMnSi Structural Alloy Steel Plate Product Description
25CrMnSi alloy metal is an alloy structural steel with slightly higher strength than 20CrMnSi low alloy steel material. After heat treatment, 25CrMnSi low alloy steel sheet can obtain a good combination of strength, plasticity and toughness, and has good weldability.
25CrMnSi structural alloy steel sheet can be interoperated with corresponding chromium-molybdenum steel under suitable conditions of use. Used in the manufacture of tie rods, important welded and stamped parts, and high-strength welded components.
25CrMnSi structural plate is used to manufacture various alloy structures and their components, such as power station boiler superheater headers, large-diameter tube plate structural parts, pressure-resistant shells, deep-diving life preservers, high-pressure structural parts, aerospace equipment, armored vehicles, etc. .
