Huaping Special Metals stocks special materials include not only the well-known nickel-base alloys such as Alloy 59, but also high-alloy stainless steels for process plant. The so-called 6 Mo materials (1.4529, 1.4539) are also in stock and available in all product forms.
One special material solution, for example, is 1.4565 / Alloy 24. This material is mainly used in chemical apparatus engineering, shipbuilding, power generation and water treatment. Recently, the Alloy 24 has also been supplied in large quantities for ship exhausts, & gas purification (Scrubber). In these applications various environmental influences come together (high chloride and sulphur content, an increased temperature and dynamic load), which places high demands on the material. With the 1.4565 we can offer a material solution with an excellent cost/benefit ratio.

Special Stainless Steel Grades

What is special stainless steel?

Special stainless steels represent a material group that is situated between the non-corrosive steels and the nickel alloys. These iron-nickel-chromium alloys differ from the ordinary non-corrosive steels by their higher alloying additions of nickel, chromium or molybdenum. Many corrosion-resistant alloys,  Furthermore, we produce a number of not nickel-containing materials, which we also consider part of our special stainless steels.

For our high-alloy special stainless steels as for our classic nickel alloys applies: each of our alloys has a unique combination of properties, depending on their chemical composition and their manufacturing process.
