How to deal with iron oxide residual problem of alloy steel Q500NH

The company is a large alloy steel Q500NH 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 alloy steel Q500NH enterprise, and make our own contribution to the development of the world economy.

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.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of alloy steel Q500NH metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

The effect of alloy elements of alloy steel Q500NH, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
