This guide explores the Nicrofer 33 composition, Alloy 33 material properties, applications, and why Gangsteel is your trusted source for Alloy 33 sheet, Nicrofer 33 plate, and round bar at competitive Nicrofer 33 price.

1. What is Alloy 33?

Alloy 33(UNS R20033), or Nicrofer 3033, is a high-chromium nickel-based alloy with molybdenum and nitrogen, engineered for exceptional corrosion resistance in aggressive environments, including sulfuric acid, nitric acid, and chloride-rich conditions. Its high chromium content (31.0-35.0%) provides superior resistance to oxidizing acids, while molybdenum and nitrogen enhance pitting and crevice corrosion resistance, making Alloy 33 sheet ideal for sulfuric acid reactors and waste incineration scrubbers. It outperforms Alloy 31 in highly oxidizing conditions due to higher chromium.

How Does Alloy 33 Compare to Alloy 31?

Alloy 33(UNS R20033) has higher chromium for oxidizing acid resistance, while Alloy 31 (UNS N08031) excels in mixed acids due to higher molybdenum and nitrogen. Alloy 33 sheet is preferred for sulfuric acid and waste incineration applications.
