NM450 material is mainly to provide protection in occasions or parts where wear resistance is needed, so that the life of the equipment is longer. Then it can reduce the maintenance and downtime brought by maintenance, and accordingly reduce the investment of funds. normalized CCS grade E bulk vessels steel, NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.
After quenching and tempering, 40Cr alloy steel plate and normalized CCS grade E bulk vessels steel sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel normalized CCS grade E bulk vessels steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.
Titanium microalloying is an element of normalized CCS grade E bulk vessels steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in normalized CCS grade E bulk vessels steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
