ASME SA 213 Seamless Pipe and Heat Exchanger Tube material supplier
GNEE is a trusted supplier, distributor, stockist, and exporter of ASTM A213 TP304L stainless steel tubes. The ASME SA 213 TP 304L specification applies to seamless ferritic and austenitic alloy steel boiler tubes, superheater tubes, and heat exchanger tubes. The ASTM A213 304L stainless steel boiler tube is made from the 304L grade, one of the most versatile and widely used stainless steel alloys.
We supply high‑quality ASME SA 213 TP 304L tubes manufactured from an austenitic grade stainless steel with 2–3 % molybdenum added to further enhance corrosion resistance. These tubes feature excellent surface quality and very low sensitization in service. The ASTM A213 304L seamless condenser tube belongs to the T‑300 series austenitic stainless steels, containing at least 18 % chromium and 8 % nickel.
