Hastelloy corrosion-resistant alloy

Hastelloy is a tungsten-containing nickel-chromium-molybdenum alloy with extremely low silicon and carbon content. As a globally recognized high-performance universal corrosion-resistant material, Hastelloy exhibits excellent stability in strong oxidizing and reducing media, and can effectively resist pitting corrosion, crevice corrosion and stress corrosion cracking.

Our Hastelloy products are widely used in chemical, petroleum, nuclear industry, pharmaceutical and environmentally friendly desulfurization systems. With advanced production technology, we ensure that every batch of Hastelloy meets international quality standards, providing solid material guarantee for your critical applications.

Hastelloy B-2

Hastelloy B-2 is an all-around corrosion-resistant alloy that exhibits excellent stability in both oxidizing and reducing media. It provides excellent general corrosion protection against a wide range of acids (especially hydrochloric, sulfuric and hydrofluoric acids) at different temperatures. In addition, the alloy effectively resists pitting, crevice corrosion and stress corrosion cracking in chloride and halide solutions.

It is an all-round corrosion-resistant alloy. It can also effectively resist pitting corrosion, crevice corrosion and stress corrosion cracking in chloride and halide solutions.

It is mainly used in reactors, heat exchangers and cooling towers in the chemical industry, reactors and drying equipment in the pharmaceutical field, and flue gas desulfurization system components. These equipment come into contact with hydrochloric acid, sulfuric acid, hydrofluoric acid or halogen-containing media, and B-2’s resistance to general corrosion is well matched to its resistance to localized corrosion.

The wire diameter range is 0.1-10mm, and the smallest can be 0.1mm. We supply spring wire, straight wire, etc.; we also provide plates (thickness 0.5-60mm), rods (diameter 6-400mm), and pipes (outer diameter 6-273mm, wall thickness 0.5-20mm), which can be customized as needed.
