304H SS Tubing & ASTM A312 TP 304H Seamless Pipe exporter & supplier in Mumbai
The grade 304H can be defined as austenitic steel that consists of 18-19% chromium and 8-11% nickel. The Stainless Steel 304H Pipe/ Tube comes with a low carbon content of around 0.08%. It is one of the most versatile stainless steel grades available and is quite popular across various industries. The Stainless Steel 304H Pipe comes with a greater short-term, and long term creep strength. They have some of the best mechanical properties: high strength, easily fabricable, excellent formability, and great corrosion resistance. The 304H Stainless Steel Tube is known for its high-temperature strength, even above 800 degrees F. The 304H SS Tubing is quite resistant to sensitization as well.
We are one of the top manufacturers of ASTM A312 TP 304H Seamless Pipe in India. Our products are used by clients across the country and worldwide too. We produce high-quality ASME SA 312 Grade 304H Welded Pipe, where we use the best raw material, and these pipes are also known for their dimensional accuracy. Our UNS S30409 ERW Pipe goes through several quality checks before they are supplied to our clients.
The WNR. 1.4948 Round Pipe we manufacture has distinct features, which makes it popular across various industries. It is suitable for high-temperature applications and offers good oxidation resistance. However, it should not be used in case aqueous corrosion resistance is a requirement.
Our SA 312 TP 304H Square Pipe provides good resistance to corrosion in strongly oxidizing or moderately aggressive organic acid environments. However, it might show a lower corrosion rate compared to the grade 304 stainless steel that comes with higher carbon content.
The ASTM A312 Gr TP 304H Rectangular Pipe can also be welded easily using standard processes. It might require annealing after the welding is complete. Sensitization leads to the loss of corrosion resistance properties, and annealing helps restore that.
We have a vast stock of AISI 304H Schedule 40 Pipe which can be used in various things. This would include boilers, pipelines, heat exchangers, steam exhausts, cooling towers, condensers, and many more. Different industries have a high demand for these pipes to serve various purposes, and hence we offer these products at a competitive price.
With us, you will get customized products that would fulfill your requirements. You will get SS grade 1.4948 Polished Pipe and unpolished pipes in different shapes, sizes, and dimensions. We offer standard shipping throughout the world and can deliver products to your doorstep.
