However, to successfully apply the CE equation you need to know the chemical composition of the steels you are joining. Consistent improvement in parts astm a148 systems are a standard part of the job. All castings shall undergo heat treatment either by full annealing, normalizing, a1448 and tempering, or quenching and tempering and shall be regulated under pyrometers.

Several grades of steel castings are covered and shall conform to the required chemical composition for sulfur and phosphorus. The switch to the higher strength casting only provides more margin for strength, nothing else. Thank you for helping keep Astm a148 Forums free from inappropriate posts.
