Classification :
PRODUCT DETAILS
EN 10083-3 4142 is a European standard quenched and tempered alloy structural steel coil, belonging to chromium-molybdenum-boron steel. It is based on 4140 with adjustments to the carbon content and boron element, further improving hardenability and strength, and possessing higher hardness and wear resistance. It has good dimensional stability after heat treatment and good machinability.
