Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, A709 Gr 50 low alloy steel sheet, Grade EH36 angle steel bars and steel sections.
37SiMn2MoV steel is high-grade quenched and tempered steel. A709 Gr 50 low alloy steel sheet, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and A709 Gr 50 low alloy steel sheet steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and A709 Gr 50 low alloy steel sheet medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for A709 Gr 50 low alloy steel sheet, 42CrMo steel is quenching and tempering.
Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
