S420ML equivalent ASTM equivalent steel grades

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium S420ML equivalent ASTM 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 S420ML equivalent ASTM 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.

We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel S420ML equivalent ASTM surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

The steel plate for water conservancy and power generation is used for ring seat, motor support structure, ship lock gate and discharge chute volute of large water conservancy generating units; the representative steel grades are S500Q, S550Q, SA516, etc., which require flaw detection and have Z-direction performance requirements; the main specifications are thickness of 120mm, 180mm, 200mm, 215mm, 270mm, and the maximum width is 4400mm. The representative steel grades of wind power steel plates include Q345E, Q690E, S420ML equivalent ASTM, etc.; the main specifications are thickness of 80mm, 100mm, 110mm, 120mm, 140mm, 160mm, 180mm, 200mm, 240mm, 260mm, 280mm, 300mm, and the width is more than 2500mm.
