ASTM A312, A213, and A249 cover TP 310 and 310S stainless steel pipes and tubes, known for excellent high-temperature resistance and corrosion resistance. These austenitic alloys contain high chromium (24-26%) and nickel (19-22%) content, providing oxidation resistance up to 1150°C for continuous use. 310S features lower carbon content (max 0.08%) for improved weldability and reduced ... https://www.kencotubes.com/astm-a312-a213-a249-tp-310-310s-stainless-steel-pipes-tubes-supplier-exporter.html
