Product Description

SKD12 1.2631 A8 High Tensile Cold Work Tool Steel Flat Bar Plate Steel
 
1. Product Introduction
SKD12 is used in a wide range of applications -Gauge,die for thread rolling,cutting tool for metal,forming roll,die for press. 

A8 is an air-hardening tool steel that is characterized by a combination of very good toughness, intermediate wear resistance, & excellent dimensional stability in heat treatment. A8 is an excellent steel for punches and dies that operate in the 55-60 Rockwell C hardness range. The combination of toughness and wear resistance make A8 an excellent choice for applications that require higher toughness than that of the high-carbon, high-chromium steels such as D2 & better wear resistance than that of shock-resisting steels.

For hot work tooling applications, A-8 provides better resistance to erosion, wear and wash-out than the typical chromium-molybdenum hot work steels such as H11 and H13. However, it is not recommended for hot applications where thermal fatigue (heat checking) is the primary failure mode.
