In production and operation, the company always attaches great importance to product P235GH boiler steel process quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market p235gh boiler steel process. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

Chromium element (Cr element) can improve the strength and hardness of p235gh boiler steel process, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Heat treatment advantages of p235gh boiler steel process, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product p235gh boiler steel process more than 15 years.
