How to improve toughness of material S890Q

A573Gr70 plate technical conditions: the chemical composition and mechanical properties of A573Gr70 steel are produced in line with ASTM A573. When ordering, additional impact, flaw detection, z direction, composition control, performance requirements beyond the standard can be added. Available heat treatment processes of material S890Q, A573Gr70 plate: hot rolling, controlled rolling, normalizing, tempering, quenching, normalizing + tempering. Our company supply flaw detection Z15-Z35 thickness direction performance.

The company specializes in the research and development, production and sales of material S890Q seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has material S890Q five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,material S890Q rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

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 material S890Q 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.

Alloying elements can strengthen the properties of structural steels. material S890Q, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
