Abstract

A method for improving the durability of extruder screw consists in chemical and heat treatment. The screw is made ​​of high-chromium steel with carbon content greater than 0.9%, which surface is strengthened by the hardening with tempering for the receiving of steel microstructure with an optimal content of residual austenite, strengthened by ion nitriding with subsequent quenching and tempering for the forming of steel microstructure with the optimum content of residual nitrogen austenite.
