Stainless Steel 304L Seamless Tubes

ASTM A249 TP 304L/304H Boiler Tubing Manufacturer in india in custom length

Stainless Steel 304L Tube has lower carbon content than the 304 grade of austenitic stainless steel tubes. The difference in the composition and the reduced carbon content provide the material with high weldability and ductility. Due to the lower carbide precipitation, the intergranular corrosion is prevented. The tainless Steel 304H Tube has higher carbon than the ordinary 304 material which improves hardness but reduces ductility.

Also, welding of these high carbon tubes require filler material but high temperatures can be applied due to high thermal conductivity compared to the lower carbon versions. The SS 304L Tubing is used in oil and gas, petroleum, petrochemical, heat exchanger and pressure vessel grade applications. Multi Metals (India) is a leading manufacturer and supplier of the UNS S30403 SS Heat exchager Tube and other special types of the tubes in 304L grade. The tubes range in diameter, wall thickness and length with schedules varying from sch5 through XXS.

Some special types such as the ASTM A249 TP 304L Stainless Steel Coiled Tubing are used in high pressure, high temperature services such as boilers and super heater elements. The low thermal conductivity of the tubes makes it necessary for low temperature welding. Please feel free to contact us for the different types of tubes such as the ASME SA 249 TP 304H Stainless Steel Instrumentation Tubes and their prices.
