304 316L stainless steel square tube seamless or welded surface
mill or bright finish
HAOSTEEL is one of the most professional manufacturer and supplier
of ASTM A312 A554 304 stainless steel Tube
Description:
Stainless Steel Grade 304 is the standard 18/8 (18% chrome, 8%
nickel) austenitic stainless steel. It is a non-magnetic alloy in
the annealed condition but becomes magnetic as it is cold worked.
It is the most commonly used of all stainless grades. TP304 can be
easily welded and is the
choice for many deep drawn, spun or formed parts due to its high
ductility.
Chemical composition:
| C | Si | Mn | P | S | Cr | Ni | N |

Application
Stainless steel pipe is a kind of economic cross section steel, is
an important product of iron and steel industry, which can be
widely used in decorative and industrial life, many people on the
market for making stair handrail, protective Windows, railings,
furniture, etc., common are two kinds of material for 201 and 304.
Stainless steel pipes are widely used in petroleum, chemical
industry, medical, food, light industry, mechanical instruments and
other industrial conveying pipes and mechanical structural parts.
According to use can be divided into oil well pipe (casing, tubing
and drill pipe, etc.), line pipe, boiler pipe, mechanical
structure, hydraulic prop, cylinder pipe, geological, chemical pipe
(high pressure chemical fertilizer pipe, oil cracking pipe) and
tube for ships, etc.
In addition, it is also widely used in the manufacture of
mechanical parts and engineering structures in the light of bending
and torsional strength and light weight.
