Frequently Asked Questions

Is Alloy 20 the same as Incoloy Alloy 20?

Incoloy® is Special Metals Corporation’s trade name for UNS N08020; the underlying grade is identical to Carpenter 20 and 20Cb-3.

Can Alloy 20 threaded fittings handle sulphuric acid at all concentrations?

Alloy 20 is specifically engineered for sulphuric acid service and performs strongest in mid-range concentrations; always confirm against your exact process chart.

What is the minimum order quantity?

Ganpat Industrial supplies from small trial lots to full container loads – share size, class and quantity for a factory-price.

Is Alloy 20 magnetic?

No. Alloy 20 is essentially non-magnetic in the annealed condition, typical of austenitic nickel-iron-chromium alloys.
