Product Description

AISI A8 1.2631 SKD12 Cold Work Tool Steel Round Steel 

Product Introduction

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.

Features

1. High wear resistance
2. High compressive strength
3. Good dimensional stability
4. Good processability
5.  Excellent resistance to temper softening
6. Good toughness
