Specifications:
AWS A5.9
AWS Class ER420
ASME SFA 5.9
UNS S42080
Description:
ER420 is similar to ER410 except it contains a higher carbon content and a semi higher hardness of weld deposits, which increases wear resistance. ER420 is often used for surfacing applications that require a resistance to corrosion and abrasion. This alloy requires preheat and interpass temperatures no lower than 400°F followed by slow cooling.
