Buying This Grade in Pakistan
A general engineering carbon steel used across the same forging, machining, and gear shops that buy the alloy steel grades, for shafts, bolts, and parts that don't need alloy steel's extra hardenability. One of the highest-turnover, most commodity grades in the catalog.
