Stainless Steel 304L Seamless Pipe is a low carbon containing version of its parent i.e. alloy grade 304. Typically the stainless steel astm a312 tp304L specified pipes produced in our factory are meant to be used in applications involved in both elevated temperature settings as well as general corrosive service.

The stainless steels of alloys 304 (S30400), 304L (S30403), and 304H (S30409) are several variants of an 18% chromium, 8% nickel austenitic alloy, the most common and commonly used alloy in the stainless steel family. Because these alloys have one or more of the following properties, they can be used in a variety of applications.

304L is a lower carbon variant of 304 stainless steel used where welding is required. The lower carbon content minimizes carbide precipitation in the heat-affected zone near the weld, which can lead to intergranular corrosion (weld erosion) of stainless steel in some environments.

These alloys are designed with a tensile strength of minimum 485Mpa and yield strength of minimum 170Mpa. TheStainless Steel 304L Pipecan be easily elongated by 35% as per requirements. These pipes and tubes are used in the transportation of gases, fluids, food industry, chemical systems, etc. We are amongst the leading 304L Stainless Steel Tube suppliers in Mumbai. We aim to produce the best products in the markets at reasonable rates.

The 304L Stainless Steel Seamless Pipe is produced without the requirements of fillets or welding. These pipes are extremely strong and a little expensive due to the materials used in their manufacturing. SS 304L Seamless Pipe can be used in very corrosive environments. They are available in different schedules and wall thicknesses to suit the different requirements of our clients. Manufactured by joining pieces of steel together, the SS UNS S30403 Welded Pipe is highly versatile.
