OK Tubrod 14.21 FCAW Type Rutile
OK Tubrod 14.21 is a flux-cored wire for out-of-position welding of 316 and 316L type stainless steels where increased resistance to pitting corrosion is required. This is particularly relevant to attack by chloride solutions and sulphurous acid. The weld metal composition is such that the stabilised 321 and 347 stainless steels may also be welded. This wire complements the OK Tubrod 14.31. Shielding gas Ar+20% CO2. Welding current, A DC+
