hardox 450 vs ar400 supplier and exporter

Hardox 450 vs ar400,Q420C Chinese steel grade is a low-alloy high-strength structural steel. It not only is high-strength steel, also is low-carbon steel. Q420C low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Product specification range: thickness 8-650mm, width 1500-4020mm, length 3000-18800mm

After quenching and tempering, 40Cr alloy steel plate and Hardox 450 vs ar400 sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of 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,Hardox 450 vs ar400.

The preparation of galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
