Superior Stainless Steel Backup flux is RoHS compliant.
Superior No. 9 Stainless Steel Backup flux is formulated for welding of stainless steel using gas, inert-gas, or metallic arc welding processes. This flux prevents oxide inclusion formation; protects the backside from oxidation; supports the molten metal; and reduces burn-through. Using a stainless steel backup flux is the most cost-effective alternative for backside welding protection in places where Nitrogen, Argon or other costly gases cannot be used, as well as when back-up bars and back-up tape cannot be used.
