Steel processing – sometimes called "steel machining" – is a group of processes that focuses on shaping parts (with desired dimensions) out of blocks of steel. Today processing of that alloy relies strongly on the machining processes like milling, turning, grinding, and steel machining (numerically controlled machines). Such methods differ by the technological …

cess. Cold-work tool steels generally are tempered at 200 degrees C (400 degrees F) or less. Because of the low tempering tem-perature involved, one temper generally is adequate for cold-work tool steels. High-speed Tool Steel. High-speed and high-alloy steels such as M2, PM-M4, and CPM-10V require a somewhat differ-ent approach to heat treating.

Different Types of Tool Steel. Tool steel is classified into six main types based on its composition, heat treatment, and intended use. Water-Hardening Tool Steel. Water-hardening tool steels (often designated as W-series) are the simplest and least expensive type of tool steel. They are primarily hardened by quenching in water, which provides ...
