Carbon density S460 ML steel with casting performance

Q460 series steel means that the plastic deformation of the steel material reaches 460 MPa, that is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel. The general quality grade symbols are respectively A, B, C, D, E. On the basis of ensuring low carbon equivalent, Q460 appropriately increases the content of microalloying elements. Good welding performance requires low carbon equivalent of steel density S460 ML, and the increase of microalloying elements increases the strength of steel while also increasing the carbon equivalent of steel.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, density S460 ML etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.

Tempering the important density S460 ML 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 density S460 ML strength, plasticity and toughness.
