Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium P235GH grade standard 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 p235gh grade standard 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.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.

Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. p235gh grade standard, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of p235gh grade standard nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of p235gh grade standard steel, can be used as an alloying element of low alloy steel.
