Carbon tool steel SAE1078, SK5,…

Features and Applications

Carbon tool steel is a popular material choice for enhancing strength and wear resistance compared to carbon steel. Hardening and tempering treatment is typically necessary for carbon tool steel. To prevent cracking during the quenching process, it is recommended to use either oil quenching or salt bath quenching. Carbon tool steel finds its application in various areas such as saws, blades, knives, agricultural machine parts, and re-rolling processes.

Workmanship and Delivery Conditions

BT steels are produced through a process where they are killed in an oxygen converter. Following refinement and continuous casting, the slabs are reheated and rolled into coils using the TMCP rolling process. After undergoing inspection, the BT steels are made available for delivery in either coil or sheet form, with the added benefit of powerful leveling and cutting capabilities. These steels can be delivered in a variety of conditions, such as TMCP, quenched, annealed, quenched and tempered, among others. We also offer processing and distribution services tailored to the specific requirements of our customers, such as pretreatment options like blasting for steel plates.
