1. What is UNS N08020?

UNS N08020is a nickel-chromium-molybdenum-copper superalloy with nickel (32.0-38.0%), chromium (19.0-21.0%), molybdenum (2.0-3.0%), and copper (3.0-4.0%), designed for superior resistance to sulfuric acid, pitting, and crevice corrosion. Stabilized with niobium to prevent intergranular corrosion after welding, UNS N08020 material is ideal for chemical reactors, heat exchangers, and food processing equipment. Compared to UNS N06625, UNS N08020 offers cost-effective performance in sulfuric acid environments with lower nickel content.

Gangsteel’s UNS N08020 alloy steel plate is tailored for aggressive chemical applications, providing a robust alternative to nickel alloy steel gradeslike UNS N06035and UNS N06985.
