Steel materials A514 Gr P quenched and tempered steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel A514 Gr P quenched and tempered steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This A514 Gr P quenched and tempered steel alloy steel A514 Gr P quenched and tempered steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A514 Gr P quenched and tempered steel.
A514 Gr P quenched and tempered steel, GB/T 16270 Q460C heavy plate is a high strength structural steel grade in quenched and tempered condition. Product A514 Gr P quenched and tempered steel stock size(mm) 6*2140*13000, 6*2080*8400, 45*1580*4900, 16*2200*9600, 12*2530*4100, 26.2*3082*4500, 16*1800*10000, 6*2160*8600, 14.5*2800*6400, 20*1600*12600, 6*2140*11500, 6*1590*8600, 22*1800*6000, 25*1800*8229, 12*2200*4300, 6*2080*8700,28.58*4343*12300, 40*2500*3400, and 81*2180*5000.
