Hastelloy G-30 Strip(ASTM B582)
Hastelloy G-30 Strip(ASTM B582)
Hastelloy G-30 Strip(ASTM B582) is a nickel-chromium-iron-molybdenum-copper alloy strip with a high chromium content and added cobalt and tungsten. Compared to most nickel-based and iron-based alloys, it exhibits superior corrosion resistance in commercial "wet process" phosphoric acid solutions and in complex environments containing strong oxidizing acids (such as nitric acid/hydrochloric acid, nitric acid/hydrofluoric acid, and sulfuric acid mixtures).
Grain boundary precipitates are not easily formed in the heat-affected zone, eliminating the need for post-weld heat treatment; it can be applied directly after welding.
The product is supplied in strip, coil, and foil forms, conforming to ASTM B582 standards, and is available in an annealed condition and various surface treatments.
Customized specifications and price reference
Customization is supported. Common parameter ranges are as follows:
Thickness: From ultra-thin 0.01 mm foil to standard 0.1 mm–3.0 mm, hot-rolled strip up to 13.0 mm.
Width: Common range 5 mm - 600 mm, with a maximum width of 1000 mm.
Supply Condition: In addition to soft, quarter-hard, semi-hard, and other hardness grades are also available.
Standards: Mainstream standards are ASTM B582 and ASME SB 582.
Reference Price: Based on market prices, our reference price is $40 to $70 per kilogram (prices may increase for special specifications or those with higher processing difficulty).

Manufacturing process and supply status
supply status
G-30 strip is typically supplied in a rolled annealed state to optimize the alloy's corrosion resistance and ductility.
Solution annealing (core heat treatment process)
Annealing temperature: 1177°C (2150°F)
Holding time: Adjusted according to strip thickness, 10–30 minutes (10 minutes for thinner strips)
Cooling method: Water quenching recommended (rapid air cooling can be used for strip thickness < 10mm)
Process purpose: To restore optimal corrosion resistance and plasticity. The material should be re-annealed after all hot forming or significant cold deformation operations.
Hot working process
Hot working methods: Hot forging, hot rolling, hot upsetting, hot extrusion, and hot forming are possible.
It is sensitive to strain and strain rate, and the hot working window is narrow. Moderate reduction and frequent reheating are recommended to avoid overheating or cracking.
Resolution annealing is necessary after hot working to restore properties.
Cold working process
G-30 is harder than most austenitic stainless steels, requiring greater energy for cold forming; it also hardens faster, potentially necessitating multiple cold working processes plus intermediate annealing.
It supports various cold forming methods, including cold rolling, stamping, deep drawing, spinning, drop hammer forming, and shearing.
Typical application areas
Wet-process phosphoric acid production: The most typical application. Its corrosion resistance is far superior to stainless steel and most nickel-based alloys. Mainly used in key equipment such as evaporators, heat exchangers, reaction tanks, pipelines, and pumps/valves.
Chemical and pickling treatment: Used in pickling lines for stainless steel and titanium materials (pickling tanks, heating coils, etc.). It can also handle harsh conditions in sulfuric acid recovery, petrochemical, pesticide, and fertilizer production.
Environmental protection and flue gas desulfurization (FGD): Used for linings of absorption towers containing high concentrations of chlorides and fluorides, demisters, and reheaters.
Key component manufacturing: Often machined into pump shafts, valve stems, agitators, and various fasteners that withstand high loads.
