It is subjected to hardening treatment that accomplishes higher mechanical properties. Our T4 High-Speed Steel Square Bars are broadly utilized in high-push applications such as Trusses, bridges, Cranes, Transport applications, and more. The combination of materials includes the high presence of titanium, which is the best metal for the alloy. Titanium in the product enhances its robustness and usefulness.
T4 High Speed Steel Square Bars can then deal with acidic attacks and their organic compounds’ effect. Such square bars are then formable and pliable to a greater extent.

High steel is very notable for its effective toughness. It is the broad resistive scope of abrasion area and corrosion. These are hardenable by heat treatment measures and followed by water. This grade doesn’t need post-weld heat treatment in the weld-affected zone because of its work solidifying rate. To fit in different segments in mechanical applications, we offered T4 High Speed Steel Square Bars in various machining allowances and resistance limits. These are actuated in cold working operations to stay away from embrittlement. Forms of the products, tensile, yield strengths, elongation, area reduction, and hardness Brinell are the different mechanical properties of these T4 High Speed Steel Square Bars. We offer these bars in a very good range for industrial applications.
