Wear resistant grating
The welding method is open arc surfacing with self shielded welding wire and alloy powder
Hardness HRC58-62
Q345 or Q235 steel plate shall be used as the specification base plate. The chromium content in the chemical composition of the wear-resistant layer shall be greater than 25%. The thickness of the wear-resistant layer shall be determined according to the actual needs of Party A.
Material density ≥ 7.8g/cm3
Material melting point ≥ 1000 ℃
Elastic modulus ≥ 380GPa
Thermal conductivity ≥ 18.85W/(m. K)
Thermal expansion coefficient ≥ 7.2E-6m/K
Relative wear ≤ 0.051G (JB/T 7705)
Impact toughness ≥ 6 (J/cm2)
The high temperature hardness exceeds the normal temperature hardness of high-speed steel at 600 ℃, and that of carbon steel at 1000 ℃.
