ER100S-1




ER100S-1
AWS A5.28 Class ER100S-1
 
ER100S-1 was developed for welding high strength low alloy steel plates such as HY80, HY100 and other similar steels. This wire
produces high tensile strength, high impact resistant weld deposits that retain their
toughness to –70°F making it suitable for low temperature and critical applications. ER100S-1 can be welded at an
interpass temperature as low as 300°F.
