StarBlaze TIG 385
AWS A5.9: ER 385 | EN ISO 14343-A: W 20 25 5 Cu L
StarBlaze TIG 385 is a W 20 25 5 Cu L / ER385 type solid TIG welding rod depositing a 20Cr25Ni5Mo weld metal, suitable for use mainly with Ar shielding gas. StarBlaze TIG 385 is used for the welding of ASTM 316 or similar steels when a ferrite-free weld metal is required. It is primarily used in cryogenic and non-magnetic applications and delivers excellent impact toughness at low temperatures. It is also suitable for welding 904L to ASTM 304 and 316. StarBlaze TIG 385 offers very good resistance to general, pitting, crevice, and stress corrosion cracking.
Diameter: 0.80 mm, 0.90 mm, 1.00 mm, 1.20 mm, 1.60 mm, 2.00 mm, 2.40 mm, 3.20 mm, 4.00 mm
Pack Sizes: 5 kg/tube, 20 kg/box
