what type of steel is best suited for case hardening
DFM DFA Training Generally, it is not necessary to normalize the carbon grades for fulfilling either dimensional or machinability requirements of parts made from the steel grades listed in the table, although where dimension is of vital importance normalizing temperatures of at least 50ºF above the carburizing temperatures are sometimes required. In the following paragraphs, we discuss the different methods of hardening that are commercially used.
The temperature range from 200°F down to room temperature is called the cracking range and you do not want the steel to pass through it. CARBURIZING.
- Carburizing is a case-hardening process by which carbon is added to the surface of low-carbon steel. If carbonitriding is performed, care must be taken to limit the nitrogen content because high nitrogen will increase their tendency to retain austenite. …
Flame hardening may be either manual or automatic.

Case hardening is ideal for parts that require a wear-resistant surface and must be tough enough internally to withstand heavy loading. NITRIDING.
This type of steel is often hardened in order to increase the outstanding hardness and to ensure core malleability. To cool the parts, you can leave the container in the furnace to cool or remove it and let it air cool.

Thanks to its microstructure and mechanical properties, hardening steel is well suited for punching, fine-blanking and cold forming. When the carburized steel is heat-treated, the case becomes hardened and the core remains soft and tough.
{ GD&T Training Geometric Dimensioning Tolerancing Flame hardening is another procedure that is used to harden the surface of metal parts. When high-carbon steels are case-hardened, the hardness penetrates the core and causes brittleness. - This process is a type of case hardening that is fast and efficient. When you add alloys to steel, the time limit for the temperature to drop below 1000°F increases above the l-second limit, and a slower quenching medium can produce the desired hardness. Alloy steels have a better hardenability, so they can through-harden and do not require case hardening.
This process produces a thin, hardened surface, and at the same time, the internal parts retain their original properties. © Copyright 2000 - 2020, by Engineers Edge, LLC www.engineersedge.com All rights reserved The higher manganese steels such as 1118 and the 1500 series are not usually carbonitrided.
