Structure and properties changes of martensitic steel X10CrMoVNb9 1 due to heat input during welding

Materials with properties like high enduring strength and creep resistance (to endure long working cycle in extreme conditions) are necessity in thermal power stations components production. Due to microstructural properties and high temperature endurance, the X10CrMoVNb9 1 is often used. As welding is mostly used joining process in production of boiler plants, the influence of welding cycle (heat input) on the properties of weldment of X10CrMoVNb9 1 steel is investigated. Metallographic and mechanical tests are conducted on the samples before and after the welding.
