Astec Tubes are prominent manufacturers, suppliers, stockists, and exporters of Stainless Steel 304/ 304L/ 304H Pipes in Mumbai, India. We manufacture these SS Pipes using high-quality raw materials and advanced technology under the guidance of professionals as per national and international quality standards. Stainless Steel 304 Pipes is the standard 18/8 (18% chrome, 8% nickel) austenitic stainless steel. It is a non-magnetic alloy in the annealed condition, however, it becomes magnetic as it is cold worked. It is the most ordinarily utilized of all stainless grades. SS 304 Pipes can be effortlessly welded and is preferred for many deep drawn, spun or formed parts due to its high ductility.

Stainless Steel UNS S30400, S30403, S30409 Seamless Pipe has oxidation resistance to a maximum temperature of 1650 degrees F (899 degrees C) continuous without considerable scaling. The maximum temperature for intermittent presentation is 1500 degrees F (816 degrees C). Since 304L is an additional low-carbon variety of 304 it can frequently be utilized in the “as-welded” condition (without annealing), even in severe corrosive conditions, except for applications indicating stress relief. SS 304L Pipe has good welding qualities and can be welded by all standard strategy; however, consideration should be paid to maintain a strategic distance from weld “hot cracking”. To relieve stress during severe forming or spinning welding may be followed by annealing.

SS 304H Austenitic Stainless Steel Pipes, 304H Stainless Steel Square Pipes, ASTM A358 Stainless Steel 304L EFW Pipes Stockist, SS 304 Pipes, SS 304 Welded Pipe, Stainless Steel 304L ERW Pipes, SS SUS 304L Welded Pipe, ASME SA 312 TP304 Seamless Pipe, SS 304 Industrial Pipes Manufacturer in India.

Stainless Steel 1.4301, 1.4307, 1.4948 Welded Pipes includes a high carbon content making the steel more suitable for utilization in applications where high temperatures are available. The benefit of this grade is that it is an austenitic chromium-nickel steel alloy as well as the greater carbon content distribute to increased tensile and yield strength. Stainless Steel 304H Pipes is recommended for utilizing in ASME pressure vessels in working service above 525 degrees C because of the grade's heat resistant properties. Stainless Steel Pipes are used in various industries such as Manufacturing, Mining, Oil Refineries, Chemical Manufacturing, Utilization, and Transport Industries. We also supply these stainless steel pipes in different sizes, specifications, thickness & grades as per customer’s requirements at the most reasonable prices.
