What type of alloy is Alloy 20?

Alloy 20 is a nickel-iron-chromium alloy containing molybdenum, copper and other controlled alloying elements.

The combination of nickel, chromium, molybdenum and copper provides strong resistance to sulfuric acid in suitable concentration and temperature ranges.

ASTM B366 / ASME SB366 can be applicable to wrought nickel alloy fittings, subject to the exact product requirements.

ASME B16.9 is commonly applicable for dimensions and tolerances of wrought butt-welding fittings.

Yes. Material Test Certificates, inspection reports and relevant quality documents can be supplied according to customer and project requirements.

Testing can include chemical analysis, mechanical testing, dimensional inspection, visual inspection, hydrostatic testing and other specified tests.
