Alloy Steel T91 Tubes Manufacturer

Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Alloy Steel T91 Tubes, which is rich in cobalt and shares many of the wear characteristics of the cobalt – based alloys. Our Alloy Steel T91 Seamless Tubes can be solution treated at 1065 Degree C (1950 Degree F) and then rapidly quenched in normal conditions that require product forms to be furnished and used. In cases where bright annealed product forms such as sheet and strip are required, these Alloy Steel T91 Welded Tubes can be solution treated at 1149 Degree C (2100 Degree F) and then cooled in a hydrogen atmosphere so as to avoid oxidation of the bright surface.

Furthermore, our Alloy Steel T91 EFW Tubes offers improved resistance to heat zone corrosion attack and to stress corrosion cracking when compared to other alloys. At the same time, by control of carbon and nitrogen, and careful selection of chromium, molybdenum, and tungsten levels, corrosion properties of many of the nickel – based alloy, such as of these Alloy Steel T91 ERW Tubes, have been attained.

Industry users like the resistance of our Alloy Steel T91 Round Tubes to a wide range of organic acids and the resistance to chloride – induced stress – corrosion cracking. These Alloy Steel T91 Square Tubes resists the formation of grain boundary carbide precipitates in the weld heat – affected zone, making it suitable for most chemical process applications in the as-welded condition.
