Injection Plastic Moud Steel Mirror Polish Capability Pre-hardened HRC40 NAK80 Round Bar Round Steel

Product Introduction

NAK80 is low alloy separate out in duration steel. It has good mechanical property after the heat-treatment with small distortion and nice mirror process under the heat-treatment and has good nitrogenated capacity, electronic capacity and welding capacity. Used for high precision mirror plastic mould and high appearance home electronic plastic mould.

SAE-AISI P21 steel is a tool steel. Cited properties are appropriate for the hardened (H) condition. P21 is the designation in both the SAE and AISI systems for this material. T51621 is the UNS number. The graph bars on the material properties cards below compare SAE-AISI P21 steel to: tool steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
