Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. 35CrMoV steel grade 34CrMo4 alloy, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

Wear resistant steel plates are mainly divided into three types: general-purpose, impact resistant and high-temperature resistant type, and their applications are also different. However, they have basically been involved in various industrial production fields, including metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, 35CrMoV steel grade 34CrMo4 alloy, wear resistant steel plates have high cost performance.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the 35CrMoV steel grade 34CrMo4 alloy steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the 35CrMoV steel grade 34CrMo4 alloy weathering steel is purified and the content of inclusions is greatly reduced.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the 35CrMoV steel grade 34CrMo4 alloy hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
