Stainless Steel 304H Pipe/ Tube
304 is an austenitic alloy that has major constituents of chromium, nickel, and carbon. The Stainless Steel 304H Pipe/ Tube is designed with a yield strength of minimum 205Mpa and tensile strength of a minimum 515Mpa. They can be easily elongated by 40% as per requirements. These pipes offer good strength at high temperatures of 500° C and up to 800° C. The 304H Stainless Steel Tube is made with higher carbon content. They are highly versatile and are highly resistant to corrosion. These tubes have excellent weldability and good mechanical properties. The 304H SS Tubing is widely used in petroleum refineries, boilers pipelines, cooling plants, electric generation plants, etc. We are the leading stockist of Stainless Steel 304H Pipe/ Tube in the country. Our ultimate goal and vision are to produce high-quality products at reasonable rates.

Pipes and tubes are designed either seamlessly or welded. The ASTM A312 TP 304H Seamless Pipe is highly corrosion resistant in various corrosive environments. These pipes are stabilized with the help of titanium and are very strong and durable in nature. The ASME SA 312 Grade 304H Welded Pipe is manufactured by welding it longitudinally with our without the help of a seam. They are available with an outer diameter of 6.35 - 114.3 mm, a thickness of 0.8-12.7mm, and a length up to 26 meters. The UNS S30409 ERW Pipe is manufactured with the help of strips and coils of 12NB. The pipes have a welded joints in their cross-section. These pipes can be easily customized in different shapes and sizes as per your needs by our experienced staff. The AISI 304H Schedule 40 Pipe is widely used for drainage, irrigation, and all types of cold water systems. All our products are produced from the best raw materials and the latest technology including the Stainless Steel 304H Pipe.
Unlike 304L, Type 304H has a higher carbon content making the steel more suitable for use in applications where elevated temperatures are present. It is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile and yield strength.
The material is recommended for use in ASME pressure vessels in working service above 525 0C due to the grade's heat resistant properties.
Benefits of using 304H Stainless Steel
Higher carbon content gives the material greater heat resistant qualities
Higher tensile yield strength
Greater short and long term creep strength.
304H Alloy is commonly found in the oil refining, gas and chemical industry and is used in industrial boilers, pressure vessels, heat exchangers, Pipelines and condensers. The material is also used throughout the power generation industry.
