PRODUCT PARAMETERS
Overview
HASTELLOY C-4 alloy is a nickel-chromium-molybdenum alloy with outstanding high-temperature stability as evidenced by high ductility and corrosion resistance 。this material is well known for their resistance to many aggressive chemicals, in particular hydrochloric acid, sulfuric acid, and chlorides.
Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions.

Corrosion Resistance
Hastelloy C4 is a highly corrosion-resistant material, standing up well to several corrosive environments, including oxidizing and reducing acid environments. It has superior resistance to pitting, crevice corrosion, and stress cracking. In addition to its resistance to acid and highly corrosive environments, Hastelloy C4 also resists intergranular cracking in welding.
HASTELLOY C-4 alloy has exceptional resistance to wide variety of chemical pro- cess environments.
Heat Treatment
Hastelloy C-4 is non hardenable by heat treatment.Hastelloy(r) C-4 is heat treated by annealing at 1066°C (1950°F) followed by quenching.
Hastelloy C4 requires careful heat treatment to achieve optimal mechanical properties. The alloy is annealed at 1025°C-1125°C followed by rapid cooling through water or air quenching. The material is then age-hardened by heating to 870°C- 980°C for one hour, followed by water or air quenching.
