Astec Tubes are prominent manufacturers, suppliers, stockists, and exporters of
stainless steel 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.
ASTM A312 TP 304H Seamless Pipe can be effortlessly welded and is
preferred for many deep drawn, spun or formed parts due to its high ductility.

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 304H 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 304H 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.
Buy custom size 304H Stainless Steel Tube & ASTM A312 Gr TP 304H Rectangular Pipe in Mumbai,
also find schedule chart/ HS/ IS Code for SS grade 1.4948 Polished Pipe.
Check grade 1.4948 Tubing, SS 304H Pipe chemical / mechanical composition, pressure rating
and specification chart, we also offer various coating for 304H Seamless Pipe in Mumbai.
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. 304h
stainless steel pipe is recommended for utilizing in ASME pressure
vessels in working service above 525 degrees C because of the grade's heat resistant
properties. SS 304L 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.
