ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and A514 grade J alloy steel plate it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.
A514 grade J alloy steel plate, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
