Quenching & Tempering For Steel Forgings | Steel Forging

Quenching is a process of rapidly cooling steel forgings from the austenitizing temperature. In ferrous alloys (such as alloy steel, carbon steel and some stainless steels), this will often produce a harder metal by transforming the austenite to martensite, while non-ferrous alloys (brass, aluminum, some stainless steels, and …

Selection of Oil Quenchants for Heat-Treating Processes

The Grossman H-Value is determined experimentally by quenching a series of round bars. After quenching, the bars are sectioned, polished, and etched. The 50 percent martensite region is determined. This is readily achieved because the transition in etching between dark and light etching corresponds to 50 percent martensite.
