Non-metallic inclusions (NMIs) play a key role in many important properties of steel, influencing both processing and application of steel products. 7 Causes of Quench Cracking in Steel :Production MachiningJul 13, 2017 · Yes, water, brine or caustic will get the steel harder. If the steel is an oil-hardening steel, the use of these overly aggressive quenchants will lead to cracking. Making an improper selection of steel for the process. Too much time between the quenching and the tempering of the heat-treated parts.
