Description
POSTALLOY 21 is a “self-hardening” wear resistant overlay engineered for abrasion and abrasion combined with medium impact. The alloy chemistry provides good resistance to spalling and chipping while the special low hydrogen coating minimizes dilution and helps to eliminate underbead cracking.
Use on carbon and low alloy steels, It can be used out-of-position and can be used with all types of AC or DC equipment.
