What are Stainless Steel 304H Tubes?

The Stainless Steel 304H Tubes have been designed by Hindco Steel And Alloys based on high-temperature and high-pressure applications hence have been found effective in all industries. Hindco Steel And Alloys being a reliable manufacturer and supplier of high quality stainless products, is also specialised in the supply of UNS S30409 grade tubes, which are manufactured on a global specification that includes ASTM A213 and ASTM A269. The fact that these tubes have a higher amount of carbon is a well recognizable attribute, and their strength in high temperatures makes them an immediate solution in the industrial sectors such as petrochemical sectors, generation of power, heat exchangers, boilers and pressure vessels among others.

The Stainless Steel 304H Tubes has high oxidative, corrosive and carburizing resistance to resist up to an environment of more than 500 o C. They possess long service life that minimizes the number of repetitive maintenance and cost due to their structural integrity even under high temperatures. This gives them the keys to be the backbones in oil and gas processing, chemical plants and refineries, thermal power stations where constant operation under pressure is a vital requirement.

UNS S30409, or simply Stainless Steel 304H is mainly an austenitic stainless steel grade, that was formed with a view to taking high mechanical stress and thermal fatigue. It is the carbon enhanced version of SS 304 and it is tailored in terms of meeting these strict industrial demands. In 304H, carbon is kept at 0.04-0.10%, which enables greater creep properties and tensile strength, especially pressure tubing.
