Common corrosion types and causes of EN10025-4 steel S275ML

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, EN10025-4 steel S275ML and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, EN10025-4 steel S275ML, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.

The purpose of EN10025-4 steel S275ML quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of EN10025-4 steel S275ML. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
