Due to the interference process, light reflecting from the oxide surface may give color … An increase in carbon or manganeses makes deeper hardening steel and less makes it slightly softer and not as deep hardening. Care needed welding. Dextrins are formed by the breakdown of starch. The tempering temperature is dependent on what hardness is required for the component. For accurate determinations of forging temperatures of the heated part, the optical pyrometers are generally used. The rate of cooling depends on the medium; therefore, the choice of a cooling medium has an important influence on the properties desired. After a metal has been soaked, it must be returned to room temperature to complete the heat-treating process. temperature of 750°F (399°C); the ½% molybdenum alloy steels to approximately 850°F (454°C); and the stainless steels to considerably higher temperatures depending upon the type used.
