Description
F91 Round Bars / ASTM A182 F91 Forged Bars
F91 Round Bars (X10CrMoVNb9-1), is an Alloy Steel with Chrome and an Addition of Nb, which has Elevated Mechanical Characteristics and it is very often used in the Chemical and Petrochemical Industries for the Fabrication of Flanges, Valves, Tubes and for Equipments that require an excellent Creep Resistance and to Embrittlement Because of Hydrogen Under Pressure and at an Elevated Temperature (Up To 600°C).
ASTM A182 F91 is a forging material specification for F91 grade alloy steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

Applications of F91 Round Bars:
F91 main fields of application of this stainless steel are typically power engineering (turbines). Advantages in these application are its properties like creep rupture behavior and proof stress at elevated temperature, and additional the behavior of the Modulus of Elasticity at elevated temperatures, and the sum of these properties with permanent load.
That´s why it is also used in power plants, general engineering, energy industry, boiler (steam boiler, boiler parts, boiler drums) and for pressure vessels in apparatus.
