This electrode is rutile basic and an all-position stainless steel electrode. It has high resistance to heat oxidation, sulphidation, and abrasion. They can stand up to 10500 C. it is suitable for both AC and DC input. It is designed for grade 309 stainless steel. It can be used in carbon, stainless and low carbon steels. It can also weld dissimilar metals. They are fully austenitic or contain some ferrite traces. They are not ideal for load bearing structures. They have low spatter, and the beats are usually clean and flat. They have excellent slag peeling ability.


Properties of stainless steel 309H

Mechanical- The electrodes have a high tensile strength of 800MPa. The yield capacity is 400MPa. The maximum elongation capacity is 25%. The metal filler is stable even under temperatures slightly above 100 degrees Celsius.

Chemical- The primary elements are carbon, sulfur, phosphorus, molybdenum, nickel, copper, silicon, nitrogen, and manganese. The high carbon content increases heat resistance. Molybdenum, nickel, and chromium enhance the stability of the alloy.
