Hot rolled S690QL high tensile steel yield strength value

SKD5 use: commonly used die-casting die steel. SKD5 steel has low carbon content, high toughness and good thermal conductivity. At the same time, it contains more carbide forming elements chromium, tungsten, and vanadium. The phase transition temperature is increased, so that the steel has high high temperature strength, hardness and good thermal conductivity. Thermal fatigue resistance; hardening. Suitable for manufacturing high temperature, high stress, but not impact load, die-casting copper, aluminum, hot top forging die, convex and concave dies, inserts, etc. of flat forging machines.

Vanadium is a weak deoxidizer. Adding vanadium into S690QL high tensile steel steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

As the thickness and hardness of S690QL high tensile steel increase, the tendency to crack at the cutting edge increases. In order to prevent the S690QL high tensile steel from cutting cracks, preheating should be carried out before S690QL high tensile steel cutting. Special attention should be paid to preheating to make the entire S690QL high tensile steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S690QL high tensile steel cannot be preheated, the partial preheating method can be used instead.
