Esha Steel is a reliable manufacturer and supplier of high-quality steel products for a wide range of industrial applications, situated in Kolkata India. After years of experience, we have a wide range of premium materials in various forms. Alloy Steel T91 Tubing is aimed at power generation, petrochemical, and manufacturing. It is strong, and resistant to high temperatures. Committed to excellence, Esha Steel sees to it that your project requirements can be met by ensuring timely deliveries, precision, and superior customer service.
The primary composition of Alloy Steel T91 Tubing consists of Chromium (9%) and Molybdenum (1%), with lesser quantities of Carbon, Vanadium, Silicon, and Manganese. This composition, among many others, provides excellent resistance to creep, oxidation, and thermal fatigue, rendering it fit for high-temperature environments. These comprise tensile strength: 585 MPa; yield strength: 415 MPa; and elongation: 20%. Further, it has superior hardness, a high creep strength, and thermal degradation resistance, which highly fit its industrial usage by power stations, petrochemical and heavy manufacturing.
