ASTM 304L Stainless Steel Welded Tube , Rectangle Polished Stainless Tube

ASTM 304L stainless steel welded structural steel metal square rectangular pipe tube
 

HAOSTEEL is one of the most professional manufacturer and supplier of stainless 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
Welded stainless steel pipe referred to as stainless steel welded pipe, commonly used steel or steel band after the unit and mold crimp forming of the steel pipe.Welding steel pipe production process is simple, high production efficiency, variety and specification, equipment investment is less, according to the welding form divided into straight welded pipe and spiral welded pipe.It can be divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen-blown welded pipe, wire bushing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, welded thin-wall pipe, welded special-shaped pipe and spiral welded pipe

304L stainless steel tube --S30403(AISI, ASTM, USA)304L corresponding Chinese brand is 00Cr19Ni10, characteristic and application: steel with lower carbon content than 0Cr19Ni9, superior resistance to intercrystalline corrosivity, is a kind of parts without heat treatment after welding.As a 304 steel with low C, the 04L stainless steel tube 18cr-8ni-low-carbon is similar to 304 steel in general state. However, after welding or stress elimination, the grain boundary corrosion resistance is excellent.Under the condition of without heat treatment, can also keep a good corrosion resistance, temperature 196 ℃ ~ 800 ℃.Used in chemical, coal and petroleum industries with high corrosion resistance to grain boundary

Chemical Composition about stainless steel Tube

Stainless steels of various kinds are used in thousands of applications. 

1. It is mainly used for direct drinking water project, other fluid transportation with higher requirements, dairy products, beer, beverage, pharmaceutical, biological, cosmetic and fine chemical industries, compared with ordinary sanitary steel pipes

2. Pipe milk for food hygiene and food industry, pharmaceutical industry, industries with special internal surface requirements

3. The stainless steel industrial tube boiler tube is mainly used to manufacture the water-cooled wall tube, boiling water tube, superheated steam tube, the superheated steam tube for locomotive boiler, large and small smoke tube and arch brick tube, and the high-pressure boiler tube is mainly used to manufacture the superheater tube, reheater tube, airway and main steam pipe of the high-pressure and ultra-high-pressure boilers.

Household appliances (type 1 and 2 tableware, cabinet, indoor pipeline, water heater, boiler, bathtub), auto parts (windshield wipers, moulds), medical appliances, building materials, chemistry, food industry, agriculture, Marine parts;
