EN 10025 S420ML steel chemical composition and properties

EN 10025 S420ML steel, 09CuPCrNi-A corrosion-resistant steel plate belongs to ordinary low-alloy steel and steel for engineering structures; it is a high-strength corrosion-resistant steel plate. The combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. 09CuPCrNi-A corrosion-resistant steel plate is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the EN 10025 S420ML steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between EN 10025 S420ML steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve EN 10025 S420ML steel work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.

We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic EN 10025 S420ML steel stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate.
