GB carbon and low alloy steel--Quenched and tempered

GB carbon and low alloy steel--GB/T 16270 Q690 steel is a high strength structural steel plates in the quenched and tempered condition. There are four quality grades under Q690 series steel:Q690C, Q690D, Q690E and Q690F.

The impact of C grade steel plate is 0°C. Q800C GB low alloy steel has high tensile strength and high yield strength. The critical hardenability diameter in oil is 60mm. GB/T 16270 Q800C steel can obtain high strength after quenching and tempering, and has a certain degree of toughness. GB carbon and low alloy steel--What is the Q620E high Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel Q620E high strength steel is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc. gb t16270 q800d steel equivalent - Hot Rolled Steel FactorySteel Plate GB/T16270 Q500E Q550D Q690F Q890F Q960D in Steel Plate GB/T16270 Q500E Q550D Q690F Q890F Q960D in Large Stock.Mechanical and chemical properties of GB/T16270 Q500E C% max Si% max Mn% max P% max S% max Cu% max Cr% max Ni% max Mo % max B % max V % max Nb% max Ti % max 0.2 0.80 1.7 0.025 0.015 0q500f data sheet - Steel .
