What Hastelloy Alloy Grades Does Zhongtongweiye Supply?

Zhongtongweiye serves many industries with high-performance metals. The company supplies several Hastelloy grades. These alloys resist corrosion and heat. Buyers often ask which grades are available. This article answers that question clearly. It also explains each grade’s main use. The goal is to help engineers and purchasers choose well.

Core Hastelloy Grades From Zhongtongweiye

Zhongtongweiye stocks Hastelloy C-276 as a leading grade. This nickel-molybdenum-chromium alloy fights harsh chemicals. It works well in sulfuric and hydrochloric acid. Pitting and stress corrosion rarely affect it. Thus, chemical plants rely on C-276 for reactors and pipes.

Another key grade is Hastelloy C-22. It contains more chromium than C-276. That feature improves resistance to oxidizing media. Chlorine and hypochlorite environments suit C-22. Zhongtongweiye supplies C-22 in plates, bars, and tubes. Fabricators value its weldability and thermal stability.

Hastelloy B-2 also appears in the product line. This nickel-molybdenum alloy excels in reducing acids. Hydrochloric acid at high temperatures is a common test. However, B-2 avoids oxidizing salts. Zhongtongweiye offers B-2 for chemical processing equipment. Users must confirm the environment before selection.

A related grade is Hastelloy B-3. It improves on B-2’s thermal stability. Welding and forming become easier with B-3. Zhongtongweiye provides B-3 for acetic acid and other organic processes. The alloy keeps strength in reducing conditions. It also resists chloride stress corrosion cracking.

Hastelloy X stands apart from the C and B families. This nickel-chromium-iron-molybdenum alloy targets high-temperature strength. Gas turbine combustors use X grade often. Zhongtongweiye supplies X for furnace parts and industrial heating. Oxidation resistance remains strong up to 1200 degrees Celsius.

Other Available Grades And Product Forms

Zhongtongweiye also offers Hastelloy C-4 and C-2000. C-4 resists intergranular corrosion after welding. C-2000 combines multiple corrosion benefits. Both grades serve pollution control and pulp processing. The company may supply these on request. Lead times depend on mill availability.

Product forms include sheet, plate, bar, wire, and pipe. Zhongtongweiye cuts materials to size for clients. Surface finishes range from hot-rolled to bright annealed. Certificates of origin and test reports come with each order. These documents help with quality audits and traceability.

How To Select The Right Grade

Start by defining the chemical environment. Note the acid type, temperature, and concentration. Then check for oxidizing or reducing conditions. Next, review mechanical needs like strength and creep. Finally, consider welding and fabrication methods. Zhongtongweiye’s technical team can advise on grade choice. They compare C-276, C-22, B-2, B-3, and X for specific cases. This support reduces trial-and-error costs.

Conclusion: Value For Global Buyers

Zhongtongweiye supplies a focused range of Hastelloy grades. C-276, C-22, B-2, B-3, and X cover most corrosion and heat duties. C-4 and C-2000 add extra options. Each grade comes in common product forms with full documentation. For buyers seeking reliable Hastelloy alloy grades, Zhongtongweiye offers a practical and business-friendly source.
