How do you weld Hastelloy?

HASTELLOY alloy X can be welded by metallic-arc, inert-gas-shielded arc, submerged-melt, and SIGMA methods. Hardness and tensile properties of welds made by these methods can be found on pages 6 and 11 respectively.

Is Hastelloy corrosion resistance?

24.3. Hastelloy X is a solid-solution-strengthened nickel-chromium-iron-molybdenum alloy that combines good oxidation resistance, high-temperature strength and exceptional stress-corrosion resistance which makes this alloy also interesting for petrochemical applications.

Is Hastelloy acid resistant?

HASTELLOY” alloy B-2 is a nickel-base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. It also withstands hydrogen chloride, sulfuric, acetic and phosphoric acids. Alloy C-22 has outstanding resistance to pitting, crevice corrosion and stress-corrosion cracking.

Can you weld Hastelloy to stainless steel?

How to weld Hastelloy c276?

Establish safe working conditions prior to the start of welding.

The welding surface and adjacent area on each side of the joint should be thoroughly cleaned and degreased prior to welding.

Oxy-acetylene welding and cutting are not recommended.

Covered electrodes used from an unopened can require no further drying.

What is Hastelloy material?

Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.
