Tools steel and Tungsten scrap

Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated temperatures. Tool steels are suited for use in the shaping of other materials.

With a carbon content between 0.5% and 1.5%, tool steels are manufactured under carefully controlled conditions to produce the required quality. The presence of carbides in their matrix plays the dominant role in the qualities of tool steel. The four major alloying elements that form carbides in tool steel are: tungsten, chromium, vanadium and molybdenum.

Oil-hardening: the O series

This series includes an O1 type, an O2 type, an O6 type and an O7 type. All steels in this group are typically hardened at 800 °C

Air-hardening: the A series

Modern air-hardening steels are characterized by low distortion during heat treatment, The series starts from A2 to A10

High carbon-chromium: the D series

originally included types D2, D3, D6, and D7, contains between 10% and 13% chromium
