Technical key points for the production of Q355GNH weathering steel plate

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the Q355GNH weathering steel plate carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, Q355GNH weathering steel plate which has high strength and good plasticity and toughness.

The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel Q355GNH weathering steel plate products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our Q355GNH weathering steel plate business. We also provide third-party inspection and approval services and inventory management for our customers.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium Q355GNH weathering 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 Q355GNH weathering 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.

What is Q355GNH weathering steel plate, boiler steel consumption rate? The cost of the boiler, to a large extent, depends on the steel consumption of the boiler. The so-called boiler steel consumption rate refers to the tons of boiler steel used per 1t / h evaporation capacity of the boiler, also known as the boiler steel consumption per unit evaporation. The boiler steel consumption rate of boilers with different parameters, capacities and structures is different.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
