ASTM A249 TP316L Austenitic Stainless Steel Welded Superheater Tubes
YuHong Group, one of the leading suppliers in China,we supply austenitic stainless steel welded tubes with high quality to our customers and we have many experiences in exporting.
ASTM A249 This specification covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic, steels with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.
Characteristic
1.High Corrosion Resistance: it can be used for a long time in various corrosive environments. This is mainly due to its excellent alloy element ratio and advanced heat treatment process, so that the surface of the steel pipe to form a layer of stable oxidation film, effectively resisting a variety of chemical corrosion.
2.High-temperature mechanical properties: it can maintain good strength and plasticity at higher temperatures.
3. Long service life, reduce maintenance time, save money.
4. Good Welding Performance: it is easy to be welded and processed. This enables the steel pipe to be easily connected and assembled during the manufacturing process, improving production efficiency.
5. Good processing performance: it can be cut, bent, drilled and other processing operations. This makes the steel tube able to meet various processing needs in the manufacturing process, improving the quality and precision of the product.
