What is acier S690QL equivalent equivalent ASTM steel

TMCP process is an indispensable technology for our production of low alloy high strength wide and acier S690QL equivalent thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy acier S690QL equivalent and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel acier S690QL equivalent is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

We have our own factory, including the production and manufacturing of steel pipes, with a special acier S690QL equivalent steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect acier S690QL equivalent after-sale service guarantee system, lets the customer save the worry and the labor.

Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.
