The company adopts the astm a581 spec international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety astm a581 spec management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.
SKD5 use: commonly used die-casting die steel. SKD5 steel has low carbon content, high toughness and good thermal conductivity. At the same time, it contains more carbide forming elements chromium, tungsten, and vanadium. The phase transition temperature is increased, so that the steel has high high temperature strength, hardness and good thermal conductivity. Thermal fatigue resistance; hardening. Suitable for manufacturing high temperature, high stress, but not impact load, die-casting copper, aluminum, hot top forging die, convex and concave dies, inserts, etc. of flat forging machines.
37SiMn2MoV steel is high-grade quenched and tempered steel. astm a581 spec, 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.
astm a581 spec, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
The executive standard of P235TR1 steel is EN 10216-1. astm a581 spec, P235TR1 steel is suitable for manufacturing pipes, vessels, equipment, pipe fittings and steel structures. Chemical composition of P235TR1 steel: C ≤ 0.16, Si ≤ 0.35, Mn ≤ 1.2, P ≤ 0.025, S ≤ 0.02, Cr ≤ 0.30, Mo ≤ 0.06, Ni ≤ 0.30, Cu ≤ 0.30, Nb ≤ 0.01, Ti ≤ 0.04, V ≤ 0.02. Chemical composition of P235TR1 steel: tensile strength 360-500 MPa, yield strength ≥ 235 MPa, elongation ≥ 25%. The main steel pipe grades under EN 10216-1 are P195TR1, P195TR2, P235TR1, P235TR2, P265TR1 and P265TR2.
