Hot Rolled S355ML material equivalent for oil tank

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable S355ML material equivalent steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

Hot rolled steel for cold forming can be divided into general purpose, stamping, deep drawing and ultra deep drawing according to its use. Common grades include S355ML material equivalent, DD11, DD12, SPHC, SPHD, SPHE steel. Hot-rolled steel for cold forming produced by our company uses low-carbon component, and has good stamping performance, welding performance and high dimensional accuracy. This material is widely used in various cold forming industries.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The S355ML material equivalent metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other S355ML material equivalent alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary S355ML material equivalent carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S355ML material equivalent carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some S355ML material equivalent alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

What is the difference between Q345B steel and Q345A steel? S355ML material equivalent, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
