Application and performance of SA514 Gr Q steel material

The company is a large SA514 Gr Q steel material steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the SA514 Gr Q steel material enterprise, and make our own contribution to the development of the world economy.

Our main product Q345R steel plate: we have large stock of Q345R heavy plates, Q345RN and Q345R(HIC) steel plate inventory. Size (mm): 8*2200*10000, 6*2150*10500, 27*2000*5700, 14*2730*4300, 32*2800*4150, 13*1600*5400, 44*2000*2000, 18*2150*4150, 7*1800*9850, 56*2980*3700, 13*1600*5400, 8*2000*5000, 18*1980*8000, 7*1800*9700, 54*2600*3880, 12.7*2230*7800, 24*2000*3150, 13*2000*6000, 7*1800*9770, 54*2500*3900, 12.7*2230*7850, 24*2640*3250, 12*2840*4850, 7*1800*9780, 53*1530*5415.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel SA514 Gr Q steel material is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

The purpose of SA514 Gr Q steel material quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of SA514 Gr Q steel material. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
