Q345D carbon steel plate sheet for bulletproof walls

Like all weather resistant steels, S355J2W is self protecting- the material rusts over time due to the reaction with chemical elements in the air. S355J2W corten steel coil and sheets have excellent impact strength and it is ideal for heavy use or in low temperature. It can be used in–situ without the need for expensive treatment or painting over time. Popular material Q345D carbon steel plate sheetwith architects for use in steel sculptures and modern structures due to aesthetic appeal.

Tempering the important Q345D carbon steel plate sheet welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve Q345D carbon steel plate sheet strength, plasticity and toughness.

The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the Q345D carbon steel plate sheet, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
