Successful research and development of 35MnB-DN steel for construction machinery

Posted:2021-04-15 15:11:07

Recently, the 35MnB-DN round steel for the tooth block of the chain rail joint developed by the company's special steel division was delivered smoothly. According to the customer's feedback, all the construction machinery chain rail tooth blocks produced using this steel grade have passed the inspection. This marks the company's successful development of 35MnB-DN steel. The successful development of this steel grade has accumulated valuable technical experience for the company’s personalized development of special steel.

It is understood that the 35MnB-DN steel grade is mainly used to make chain rails for construction machinery. It belongs to track steel, and the track is a wear part. The material must have good wear resistance, as well as sufficient strength and toughness. The customer not only requires vacuum smelting of the steel, but also requires the material to have good cleanliness and to ensure that the three-point end hardenability inspection is qualified.
