This guide explores the Hastelloy G30 composition, G30 material properties, applications, and why Gangsteel is your trusted source for Alloy G30 plate, Hastelloy G30 pipe, round bar, and tubing at competitive Hastelloy G30 price.

1. What is Alloy G30?

Alloy G30(UNS N06030), or Hastelloy G-30, is a wrought nickel-based alloy developed by Haynes International, optimized for corrosion resistance in wet-process phosphoric acid and sulfuric acid environments. With high chromium and added copper, G30 material resists pitting, crevice corrosion, and stress corrosion cracking, outperforming Alloy C276 in phosphoric acid applications. Its low carbon content ensures weldability, making Alloy G30 plate ideal for welded structures in fertilizer and chemical processing equipment.

How Does Alloy G30 Compare to Alloy C2000?

Alloy G30(UNS N06030) has higher chromium (28-31.5% vs. 15-17%) than Alloy C2000, offering superior resistance to oxidizing acids like phosphoric acid, while Alloy C2000 excels in reducing acids due to its copper content. Both alloys are weldable, but Alloy G30 is preferred for phosphoric acid service.
