Product Description

A2 Round Steel Bar Feature It is a air quenching tool steel and have a deep air quenching & hardening ability. This is a big advantage to the complex mould to maintain its shape after quenching and tempering. 1.small deformation after air quenching ***** abrasion resistance and excellent tenacity ***** suitable to Applications For making all sorts of tool steel with good abrasion resistance and good tenacity including forming block, roll, drawing die, punch, thread rolling die and some bill.
