alloy steel nm500 steel material strip price
The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of , No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.The company has advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
NM500 steel material,No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than Annealing and normalizing are better than quenching and tempering No 45 steel has higher strength and better machinability than Q345 steel After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance No 45 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding Preheating is required before welding, and stress relief annealing shall be conducted after welding,
NM500 steel material.
NM500 steel material,The microstructure of the quenched and tempered alloy steel after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
