The delamination problem of HARDOX400 steel material

Q370R grade is a Chinese steel material for boilers and pressure vessels. "Q" means yield strength, "370" means yield value, and R means container. Delivery status of Q370R steel plate: normalizing -20℃ impact. The steel product HARDOX400 steel material can also be subjected to controlled rolling treatment or normalizing treatment according to the requirements of the manufacturer or design. The Q370R plates thickness are produced with up to 150mm.

The company adheres to the HARDOX400 steel material external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of HARDOX400 steel material quality and price and best service for all our customers.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The HARDOX400 steel material cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used HARDOX400 steel material, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel HARDOX400 steel material plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
