Anti Corrosion Hastelloy G3 Seamless Nickel Alloy Tube N06985 ASTM SB 407
Hastelloy G3 Nickel base corrosion resistant alloy Seamless tube N06985
Introduction
Hastelloy G3 / N06985 Nickel base corrosion resistant alloy is a nickel-based corrosion-resistant alloy with excellent properties, which belongs to the Ni-Cr-Fe series containing Mo and Cu. It has excellent resistance to oxidation and atmospheric corrosion and stress corrosion cracking resistance, and has high resistance to local Ability to corrode (pitting, crevice corrosion). Because the alloy contains higher Fe, it has a lower cost than other nickel-based corrosion resistant alloys.
