Uns N10276 Nickel Chromium Molybdenum Incoloy ASTM Hastelloy C22 Round Bar 690 MPA Tensile Strength

Product Introduction

Hastelloy C22 Bar is a high-performance nickel-chromium-molybdenum-tungsten alloy with excellent corrosion resistance and high temperature stability. Its chemical composition includes nickel (Ni) balance, chromium (Cr) 20.0-22.5%, molybdenum (Mo) 12.5-14.5%, tungsten (W) 2.50-3.50%, iron (Fe) 2.00-6.00%, etc. This alloy performs well in various strong acids, strong alkalis and salt solutions, and can resist corrosive media such as chlorides, sulfuric acid, and nitric acid.
Hastelloy C22 Bar has a wide range of applications in marine engineering, mainly due to its excellent corrosion resistance and high mechanical strength. This alloy can effectively resist corrosive media such as chlorides and chloride ions in seawater, and is suitable for manufacturing key components such as offshore platforms, submarine pipelines, valves and seawater treatment equipment. The precise chemical composition ratio of Hastelloy C22 alloy enables it to maintain good mechanical properties and oxidation resistance under high temperature and high pressure environments, ensuring long-term stable operation of the equipment. In addition, its good processing and welding properties enable Hastelloy C22 Bar to meet the requirements of various complex shapes and sizes in marine engineering.
