This guide explores the Sanicro 28 composition, Alloy 28 material properties, applications, and why Gangsteel is your trusted source for Alloy 28 sheet, Sanicro 28 plate, and round bar at competitive Sanicro 28 price.

1. What is Alloy 28?

Alloy 28(UNS N08028), or Sanicro 28, is a nickel-iron-chromium alloy developed for superior corrosion resistance in highly acidic environments, particularly phosphoric and sulfuric acids. With high molybdenum (3.0-4.0%) and copper (0.6-1.4%), Alloy 28 material resists pitting, crevice corrosion, and stress corrosion cracking, making Alloy 28 sheet ideal for chemical reactors and oilfield equipment. It offers better weldability than Alloy C276 in phosphoric acid environments, with excellent performance in wet-process phosphoric acid production.

How Does Alloy 28 Compare to Alloy 31?

Alloy 28(UNS N08028) has higher copper content for phosphoric acid resistance, while Alloy 31 (UNS N08031) offers superior resistance to nitric acid and mixed acids due to higher chromium and nitrogen. Alloy 28 sheet is preferred for phosphoric acid service in chemical processing.
