Superior No. 9H welding back–up flux is formulated for MIG and TIG welding stainless steel and low nickel (less than 20%) heat resistant alloys. The flux prevents oxide inclusion formation, protects the backside from oxidation, supports the molten metal, and reduces burn-through. It is a more cost-effective means of achieving backside protection than other alternatives, including back-up bars, inert gas purge, back-up tape, and even other back-up fluxes. Additionally, the flux can be placed in areas where back-up bars or back-up tapes are impractical; such as parts with irregular shapes or bends

• Formulated for inert-gas, metallic-arc, and/or gas welding of stainless steel, high chromiumferrous alloys, and low nickel alloys
• Provides significant protection and improves weld quality
• Most cost-effective alternative for backside protection in lieu of nitrogen, argon, or other gases
• Form: Fine gray powder
• Specific gravity: 2.5 (average)
• Volatile content: <0.1%
• This product is RoHS compliant
