*Micro Alloy 1045 uses Vanadium as a grain refiner. Mpa is an abbreviation for Megapascals.
1045 has a very good heat treatment response. It is the most commonly used, and most economical, grade of shafting in use for hydraulic cylinder components, blower shafts, and mandrels. Items of 1045 are stocked from 1/4" diameter through and including 14" diameter, and in metric diameters from 10mm through and including 250mm.
