Washington Alloy “A” is a nickel-chromium-iron flux-coated electrode designed primarily for shielded metal arc welding of Incoloy®800 to itself or to 9% nickel steels. This electrode is used for welding a variety of dissimilar wrought or cast forms of carbon steel, austenitic and ferritic stainless steel, and nickel-chromium Inconel®600 to themselves or to each other. Washington Alloy “A” is frequently used for joining Incoloy ®800 to high nickel alloys 200 and 201 or to nickel-copper Monel®400 and K-500. Washington Alloy “A” is excellent for overlaying nickel-chromium alloy on steel. More common applications include the welding of 5%and 9% nickel steel transport or storagetanks used for cryogenic products. The chemical or petrochemical industries use Washington Alloy “A” for many applications such as valve seats andgates, coal gasification and wet process desulphurization equipment.
