Supply heavy SA514 grade P steel material comprehensive properties

Q420C Chinese steel grade is a low-alloy high-strength structural steel. It not only is high-strength steel, also is low-carbon steel. Q420C low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Product specification SA514 grade P steel material range: thickness 8-650mm, width 1500-4020mm, length 3000-18800mm

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for SA514 grade P steel material and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

SA514 grade P steel material, Structural steel is a kind of steel which meets the strength of specific specifications. Structural steel can be divided into: alloy structural steel, carbon structural steel, low alloy structural steel, heat-resistant structural steel and so on. According to different uses, structural steel can be divided into construction steel and mechanical steel. Construction steel is used to build boilers, ships, bridges, workshops and other buildings. Mechanical steel is used for manufacturing machinery or mechanical parts. Mechanical steel is often used after carburizing or quenching and tempering.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.
