Deepak Steel India is a known exporter of Alloy Steel T91 Seamless tubes. These tubes are rich in Cobalt and share many common characteristics of Cobalt-based alloys. These tubes are treated at 1950 degrees Fahrenheit and then quenched in normal conditions, which require the product to be well furnished for use. In places which need these tubes to form sheets and strips, these tubes can be solution treated at 2100 degree Fahrenheit and then onwards cold inside a hydrogen atmosphere which avoids oxidizing the bright surface.

These tubes offer excellent and improved resistance to heat and stress corrosion cracking as compared to the other alloys available in the market. Simultaneously by controlling the carbon and nitrogen and carefully selecting molybdenum, chromium, and tungsten levels, the corrosion properties of nickel-based alloys have been attained.

These tubes offer resistance to a wide range of organic acids and chloride-induced stress – corrosion cracking. We are India’s most recognized supplier of alloy Steel t91 welded tubes. We are also one of India’s most prominent exporters of these tubes.

We provide you would the best possible T91 Alloy Steel Seamless Tubes at the reasonable price range. If you are looking to buy these T91 Alloy Steel Seamless Tubes, then please contact us today and get a free estimation.
