Round aisi tube prices 304 316 321 2205 stainless steel pipe
HAOSTEEL is one of the most professional manufacturer and supplier of 304 304Lstainless steel Tube.Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.
Description:
304 stainless steel tube has good anti-intercrystalline corrosion
performance, excellent corrosion performance and cold processing,
stamping performance, can be used as heat-resistant stainless
steel.
At the same time, the steel - 180 ℃ under the condition of the
mechanical properties of this dismal disease.
Under the condition of solid solution, the steel has good
plasticity, toughness and cold working ability.
The 304 stainless steel tube is a kind of universal stainless
steel, which has beautiful surface and strong corrosion resistance.
It also has good corrosion resistance to alkali solution and most
organic acids and inorganic acids.
In the air or chemical corrosion resistant to corrosion medium of a
kind of high alloy steel, stainless steel pipe products are fluid
conveying stainless steel seamless steel pipe, stainless steel
seamless tube structure, boiler, stainless steel seamless steel
tubes for heat exchanger, decorative stainless steel pipe welding,
building decorative stainless steel welded pipe, all pass strict
examination, conform to the requirements of the national standard
of technical indicators, no blister, no sand hole, no black spots,
no cracks and weld is flat and level.
Bending, cutting, welding and processing performance advantages,
nickel content is stable, widely used in the production of
equipment and parts requiring good comprehensive performance
(corrosion resistance and molding), used in food equipment, general
chemical equipment, nuclear industry equipment.

Application:
1. Production equipment for seawater, such as chemistry, dye, paper
making, oxalic acid and fertilizer;
2. Food equipment, general chemical equipment and nuclear energy
industrial equipment components are widely used.
3. It is suitable for deep drawing parts, acid transportation
pipes, containers, etc. The steel type is also used in household
appliances of vehicle and automobile parts box.
4. It is the steel with the most production and consumption in
austenitic stainless steel, used in the production of thin-walled
parts, acid transport pipelines and structural parts, etc.
5. It is often used as core material for welding chromium-nickel
stainless steel and stainless steel, non-magnetic parts and parts
used under low temperature.
6. Images, equipment in coastal areas, ropes, CD bars, bolts, nuts,
etc.
