An "SS 316H angle" refers to a specific type of stainless steel angle produced from grade 316H steel. SS 316H is a high-carbon version of the popular 316 stainless steel alloy, with increased strength and heat resistance ideal for high-temperature environments. The angled shape is perfect for structural support, framing, and other construction applications requiring strength and corrosion resistance. With its exceptional durability and corrosion resistance, SS 316H angle is used in industries including marine, chemical processing, and aerospace, where severe conditions are widespread.

SS 316 and SS 316H are both stainless steel alloys, although they differ principally in carbon content, determining their intended applications and qualities. SS 316 is a standard grade of stainless steel with a maximum carbon content of 0.08%. It has good corrosion resistance and is often utilised in areas where corrosive materials are a problem, such as the maritime and chemical processing industries.

SS 316H Angle is primarily made of iron (Fe), with considerable amounts of chromium (Cr), nickel (Ni), and molybdenum (Mo). The chemical composition consists typically of 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, which gives it high corrosion resistance. In addition, minor amounts of other elements such as carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulphur (S), and nitrogen (N) are present, which contribute to the material's mechanical qualities and overall performance in diverse settings.
