Non-alloy S420ML equivalent ASTM data sheet

How to quickly judge whether the price of S420ML equivalent ASTM, weathering steel plate is reasonable? What are the factors influencing the price quotation of S420ML equivalent ASTM, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of S420ML equivalent ASTM, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the S420ML equivalent ASTM, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.

Grades S420ML equivalent ASTM, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

The purpose of S420ML equivalent ASTM 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 S420ML equivalent ASTM. 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.

Our focus on quality has helped us create an efficiently organised production system, which can supply large-scale piping orders as well as tailor-made orders for smaller clients. We have also created a sales and support network which stretches from Asia to Europe, UAE, South Africa and South America.
