Stainless Steel 310H Tubes, Seamless & Welded Tubes Manufacturers in India- UNS S31009 Stainless Steel Tubes 

Metline is a specialist manufacturer and supplier of 310H stainless steel tubes with Bright Annealing (BA Tube) or Polishing (Surface Roughness Ra 0.18). We produce 310H stainless steel tubes outside diameter 6mm upto 5″, in wall thickness upto 10mm. Metline is a professional producer of both thin wall and thick wall stainless steel tubes, with exports to over 70 countries across the globe. In addition to 310H stainless steel tubes, we can also produce and supply related tube fittings such as ferrule fittings, compression fittings, and couplings and valves.

Pipes are used to transport something, and tubes to construct something; hence, tubes are defined by the outside diameter and wall thickness (for construction stability), and pipes are measured by inside diameter to allow a calculation for transportation viz., speed, volumes, etc.

About 310 Stainless Steel Tubes

Stainless Steel 310, combining excellent high temperature properties with good weldability and ductility, is designed for high temperature service. SS 310 resists oxidation in continuous service at temperatures up to 1150°C provided reducing sulfur gases are not present. SS 310 is also used for intermittent service at temperatures up to 1040°C

Stainless Steel 310S is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered “high temperature” service. The lower carbon content of SS 310S does reduce its high temperature strength compared to 310.
