Performance characteristics of S420MC steel for car safety parts

Characteristics of 50CrMo4 steel: 50CrMo4 steel has high strength and toughness, good hardenability and no obvious tempering brittleness. 50CrMo4 steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness.

Characteristics of 50CrMo4 steel: 50CrMo4 steel has high strength and toughness, good hardenability and no obvious tempering brittleness. 50CrMo4 steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness. 50CrMo4 steel can be used to manufacture the big gear for locomotive traction, booster drive gear, S420MC steel for car safety parts pressure vessel gear, rear axle, connecting rod and spring clamp with great load, as well as the drill pipe joint and fishing tool for oil deep well below 2000m, and 50CrMo4 steel can also be used for the die of bending machine, etc.

NM400 wear plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other product parts. Such as excavator, loader, bulldozer bucket plate, blade, side blade, crusher liner, etc.. NM400 wear plate is also commonly used as high-strength structural steel with yield strength ≥ 800MPa. The main function of NM400 wear plate is to provide protection in places or parts where wear resistance is required, so as to prolong the service life of the equipment.

In actual processing applications, the processing S420MC steel for car safety parts thickness of flame cutting ranges from 6 to 200 mm, and the S420MC steel for car safety parts cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting S420MC steel for car safety parts with a certain thickness above 10mm.
