What is the ASTM equivalent to NM400 material meaning

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products NM400 material meaning are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

10 to 20mm thick NM400 material meaning product: 10*2200*7200, 10*2200*8000, 12*2000*11850, 12.5*2900*11000, 12.9*2987*10384, 13.6*2940*11455, 14*2000*10000, 14*2000*11181, 14*2000*13500, 14*2070*9060, 14*2200*10030, 15*2200*10270, 15*2500*10000, 15*2992*10185, 16*1500*9340, 16*1800*6000, 16*2000*10713, 16*2120*6080, 16*2200*10000, 16*2230*7650, 18.5*2320*6600, 20*1400*11400, 20*2100*7000.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the NM400 material meaning metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between NM400 material meaning strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
