Hastelloy G30 | UNS N06030
Hastelloy G30 alloy is a type of material that is made up of nickel, chromium, and iron. It is highly resistant to wet process phosphoric acid, which is a crucial chemical in the production of fertilizers.
This material is moderately resistant to localized attack caused by chloride, which can cause problems in the evaporators used to concentrate P2O5. In addition, it is less likely to experience chloride-induced stress corrosion cracking than stainless steel.
Due to its high chromium content, Hastelloy G30 alloy can also resist other oxidizing acids like nitric acid and mixtures containing nitric acid. It can also tolerate reducing acids like hydrochloric and sulfuric acid thanks to its molybdenum and copper contents.
Trusted Hastelloy G30 Manufacturer in China – Tuolian
In terms of formability, our Hastelloy G30 is similar to other alloys. It is typically stiffer than austenitic materials, but still has good ductility. This makes it easy to work with through cold working, which is often the preferred method of forming the material.
The material is also easy to weld, and can be welded using various methods such as Gas-Tungsten Arc, Gas Metal Arc, and shielded Metal Arc. The welding characteristics are similar to those of G-3, another type of HASTELLOY alloy.
At Tuolian, we offer Hastelloy G30 in variety of forms such as plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes.
Whether you need custom sizes, cut-to-length, custom dimensions, and other specific Hastelloy G30 forms, Tuolian is your best supplier. Send us your inquiries today!
