Non alloy steel – case hardened, quenched

acciai non legati

Properties
Non alloy steel is steel in which the alloy elements fall within the limits set by the UNI EN 10020; steels from this group often called ‘general use’ are the most widespread on the market in terms of quantity.

Non-alloy case hardened steels don’t contain any other alloying elements a part from carbon. They are often quenched in water making them adapted for the production of parts with a simple form and not particularly difficult uses such as pivots and bushings.
Non-alloy quenched steels are limited in their tempering potential and so accuracy can only be obtained on smaller parts.
