Alloy 28 Studs
Alloy 28 studs is a metal rod or bar with threads on both sides. It also known as double-headed screws or studs, used to connect two parts together. General for mining machinery, bridges, cars, motorcycles, boiler steel structure, hanging tower, large span steel structure and large buildings.
We tend to use studs when the parts need to remove frequently, because the thread will be worn if install and remove often, then we need to change the studs.
Alloy28 alloy has the following characteristics:
Alloy 28 alloy with high chromium content up to 27% and Mo containing high austenitic stainless steel, is to solve the wet phosphoric acid heat exchanger material developed, is currently in the wet phosphoric acid application of the best corrosion resistance of the material The The increase in CI- and F-content in wet-process phosphoric acid leads to increased corrosion of the material, which limits the CI-, F- increase in wet-process phosphoric acid compared to other alloys.
The alloy stainless steel with the highest nickel content, due to the amount of Ni> 30%, and sometimes it will be included in the iron-based corrosion-resistant alloy. In addition to nickel, this steel has a high Cr content and contains 3% to 4% Mo and about 1.0% Cu, so it is excellent in overall corrosion resistance in many strong reducing corrosive environments, and in some oxidizing, Halogen-containing medium, both resistant to comprehensive corrosion, and resistance to local corrosion. In addition, this steel has austenitic structure, its strength and plastic, tough fine. So the steel is a comprehensive performance matching excellent steel.
