Effect of grain size on yield strength ratio of nm400 steel grade

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the NM400 steel grade, alloy wear-resistant steel plate is significantly improved.

The work performance of NM400 steel grade etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.

Global NM400 steel grade crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global NM400 steel grade crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the NM400 steel grade project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of NM400 steel grade customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
