Stainless Steel 316H Flanges Manufacturer, Supplier & Exporter in India
Astromet Steel & Engineering supplies Stainless Steel 316H Flanges, which are specially engineered for high-temperature and high-pressure environments. The higher carbon content in SS 316H enhances creep strength and mechanical stability at elevated temperatures, making these flanges suitable for severe service conditions. Despite the increased carbon content, SS 316H retains excellent corrosion resistance similar to SS 316 grades.
These flanges provide outstanding strength, fatigue resistance, and pressure containment capabilities, making them ideal for continuous high-temperature operations. Astromet Steel & Engineering ensures precision forging and strict quality control to deliver flanges that meet international pressure vessel and piping standards. The robust construction of SS 316H flanges ensures extended service life even under extreme thermal stress.
Stainless Steel 316H flanges are extensively used in power generation plants, boilers, heat exchangers, petrochemical refineries, and high-temperature chemical processing units. Their ability to maintain performance under sustained heat and pressure makes them a preferred choice for critical industrial systems.
