Strength of Alloy Steel T91 Material

Eckhardt Steel & Alloys designated as is seamless and intended for use in high temperature applications. These T91 materials, which include Alloy Steel T91 Tube and SA213 T91 Seamless Tube, are appropriate for fusion welding in power plants and petrochemical facilities as well as high temperature applications including bending, flanging, and similar shaping processes. Due to the chemical composition of molybdenum and chromium, SA213 T91 Alloy Steel Tubing is also known as ASTM A213 T91 Chrome Moly Tube (Cr). The ASME SA213 T91 square tube's strength, elastic limit, wear resistance, impact properties, and hardenability are all maintained by molybdenum. The most efficient additive for improving the high temperature creep strength of ASTM A213 T91 Tubing is moly.

Long Distances Hot rolled ASME SA213 T91 Seamless Tube & High Pressure T91 Boiler Tube are offered up to 22.5m. Ferritic alloy steel T91 tubes can be supplied with close diameter and wall thickness tolerances as well as unique surface requirements. Cold-drawn ASTM A213 T91 Alloy Steel Tubes are offered in tight tolerances, up to 25m in length, in both conventional and non-standard specifications, or with regulated inside diameters. We offer a full size variety of Alloy Steel T91 Tubing & AS T91 Chrome Moly Tubing, including T91 combustion chamber tubes, T91 heater tubes, T91 header tubes, and T91 line pipe for main steam and reheater circuits, in all needed alloy steel grades.
