High tensile steel grade S690QL material equivalent suppliers

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as S690QL material equivalent. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

ASTM A588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of A588 and expand its application range. Firstly, the alloy composition increases the S690QL material equivalent yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, A588 S690QL material equivalent has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, A588 angle steel is widely used in bridge, building and other structural fields.

In terms of inventory, the recent arrival of new S690QL material equivalent resources is relatively small. Due to the high ordering cost, the weakening of merchants' purchasing enthusiasm, and the rapid production of steel mills, resulting in the shortage of some S690QL material equivalent specifications. On the whole, the market has a strong wait-and-see mood. The ex factory prices of steel mills are strong and some resources are in short supply. It is expected that S690QL material equivalent prices will continue the high consolidation operation tomorrow.
