Specifications:
AWS A5.9
AWS Class ER320LR
ASME SFA 5.9
UNS N08022
Description:
Lower elements of C, Si, P, and S reduce weld metal hot cracking and fissuring while maintaining the corrosion resistance frequently encountered in fully austenitic stainless steel weld metals. Filler metals of this classification are typically used to weld metals of similar composition for applications where resistance to severe corrosion involving a wide range of chemicals–including sulfuric and sulfurous acids and their salts–is required.
