Alloy 304 is an austenitic alloy, which is made up major constituents of nickel and chromium. The Stainless Steel 304 Pipe/ Tube is designed with high corrosion and oxidation resistance properties. These alloys have excellent formation as well as welding properties. Apart from that, they are easy to clean and fabricate. The 304 Stainless Steel Tube is designed with a yield strength of up to 250,000 psi. They are widely used in the food industry, transportation of liquids and gases. It is also used in domestic appliances and applications due to its versatile properties. We are the leading manufacturers of Stainless Steel 304 Pipein the country. Our vision is to produce the best products at reasonable rates which are available to all. We are the leading SS 304 Pipe suppliers who can customize all our products in different shapes and sizes to fulfill all your requirements.
Most stainless pipes are produced either seamlessly or through a welding process. The SS 304 Seamless Pipe is made from a single piece of metal and is stronger as compared to a welded pipe. However, these pipes are expensive due to their unique manufacturing process. The ASTM A312 TP304 Seamless Pipe cannot be properly regulated for side width and diameter. This pipe is a low-pressure pipe that can also be used for high-pressure systems. The thickness of the pipe determines the pressure rating of these pipes. The ASME SA 312 Grade 304 Welded Pipe is formed by welding seam longitudinally with or without a filler. These pipes can be hot or cold-rolled to get desirable properties. The Polished 304 Stainless Steel Pipe provides a smooth finish and increased resistance to steel pipes. Our renowned workers make use of the best raw materials and the latest technology while producing all our products, including the SS 304 Tubing.
The AISI 304 Schedule 40 Pipe possesses an excellent yield strength of minimum 215Mpa, and yield strength of minimum 505Mpa. Its cost-effectiveness makes it a preferred grade. The ASTM A312 Gr TP304 Rectangular Pipe has general corrosion resistance. It can suffice in temperatures of up 870 degrees C and is used in boilers and heat exchanger tubes. The DIN 1.4307 Round Pipe is a low-carbon steel pipe. These pipes can be added with other chemicals to give them desired properties. These low-carbon pipes, however, suffers from yield-point runout. The SA 312 TP304 Square Pipe can be easily installed in difficult areas in houses and buildings.
A UNS S30403 ERW Pipe is designed with steel coils using both low and high-frequency resistance. Our experienced staff uses the latest technology and the best raw materials while producing the best products.
