AWS A5.14 – ER NiCrMo-13

A 5KG pack of Weld Star 2.4mm Alloy 59 TIG Welding Wire (NiCrMo-13). Designed for welding alloys 22, 625, 276 and 686 as well as a combination of them.  This versatile alloy has excellent resistance to wet corrosion for some of the most demanding applications including papermaking equipment, producing corrosion resistant overlays and use in severe offshore environments.

Due to the chemical composition of Weld Star Alloy 59 TIG Filler Rods they possess an excellent capacity to resist an extensive range of corrosive issues.  In particular chloride induced pitting and crevice corrosion, plus excellent resistance to stress cracking corrosion.  Additionally they have a great ability to withstand the effects of mineral based acids such as nitric, phosphoric, sulphuric and salt acids.  Moreover Alloy 59 TIG Filler Rods have exceptional mechanical strength. Like C276 TIG Rods, Alloy 59 also have high levels of Molybdenum(Mo).  However they perform better in a wide range of oxidising media’s in comparison to C276.

As a result of their exceptional resistance to many forms of corrosion, Weld Star Alloy 59 TIG Filler Rods are used in the most severe environments such as Chemical processing plants, scrubbers for flue gas desulphurisation, digesters and papermaking equipment. Plus industries including offshore and petrochemical where some of the most severe corrosive factors are confronted.

What is wet corrosion?

Wet corrosion takes place when humidity levels in the presence of metal surfaces exceed 60% and can occur in neutral, acid or alkaline environments.  As a result various forms of corrosion can take hold both at a uniform / wider level e.g. oxidation, and also at the localised level e.g. pitting and crevice corrosion.  With particular concern for localised corrosive issues as they can often go undetected, leading to serious failure of weld integrity and strength. Wet Corrosion can be concentrated in areas where there is a limited oxygen supply leading to more intense effects.  The following list highlights some of the main forms of Wet Corrosion to be aware of:

  • Pitting & Crevice Corrosion
  • Uniform Corrosion
  • Environmentally Assisted Cracking
  • Stress Corrosion Cracking
  • Sulphide Stress Cracking
  • Hydrogen Induced Stress Cracking
  • Corrosion Fatigue

While the above list is not exhaustive it does cover the main issues to consider in the name of Wet Corrosion.
