The term hardened steel is often used for a medium or high carbon steel that has been given heat treatment and then quenching followed by tempering. The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering. This is the most common state for finished articles such as tools and machine parts. In contrast, the sa… WebIn general, the first number of each grade depicts a general category of steels.

There are now almost 50 grades available in the nonresulfurized series 1000 carbon steels and nearly 30 grades in the resulfurized series 1100 and 1200. WebMay 6, 2024 · Hard carbide grades have smaller grains, and tough grades have larger ones. Hard grades need less cobalt binding to hold their grains together, which promotes better heat resistance for longer tool life during continuous cutting than with softer grades. small things nthikeng mohlele summary
