Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A514 grade E QT steel plate 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 A514 grade E QT steel plate 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.
In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate A514 grade E QT steel plate provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.
