What is chemical composition of 1.8904 EN 10025-6 high strength steel

Pressure vessel steel SA204GrA, SA204GrB, SA204GrC sheet delivery status: normalized rolling, maybe normalized, or other heat treatment methods may be negotiated with users for delivery. Generally, the thickness of the 1.8904 EN 10025-6 high strength steel, ASME SA204 pressure vessel steel plate is ≤40mm, and it is generally delivered in the rolled state, and the SA204GrA steel plate of more than 40mm can be delivered in the normalized heat treatment state.

In recent years, in line with the development trend of iron and 1.8904 EN 10025-6 high strength steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 1.8904 EN 10025-6 high strength steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium 1.8904 EN 10025-6 high strength steel 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 1.8904 EN 10025-6 high strength steel 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.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, 1.8904 EN 10025-6 high strength steel, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our 1.8904 EN 10025-6 high strength steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's 1.8904 EN 10025-6 high strength steel customer service to establish a good, comprehensive, full service system.
