SMA570P Introduction to high-temperature alloy steel plate and industrial application
ntroduction to SMA570P Steel Plate: SMA570P Corrosion-resistant Steel Plate:
SMA570P Steel Plate has high wear resistance, long life of all kinds of cold stamping dies and cold shear blades, thread rolling plates, etc. It is suitable for complex tool molds that may be deformed.
SMA570P Characteristics of corrosion-resistant steel plate 1. Vacuum refining steel is pure, vacuum refining steel is pure 2, spheroidization annealing softens the structure, and it is easy to cut 3. It has high hardness during quenching 4. It has good dimensional stability after tempering

SMA570P quenched and tempered high-strength plate processing performance: steel plate can be cold worked, bent and cut. When the gas is cut off, cracks do not occur even if it is not preheated. When preheating, quenched and tempered steel is processed below the tempering temperature. High wear and corrosion resistance: Due to the presence of copper, chromium and other alloying elements, compared with general steel, it has good corrosion resistance, high hardness, and good wear resistance.
