Influence of Ni on the Microstructure and Mechanical

The microstructure and mechanical properties of the high-strength low-alloy steel weld metals with a variation of nickel content were investigated.The weld metals with a variation of nickel content from 2.3 to 3.3 wt% were prepared using Gas Metal Arc Welding process.The amount of acicular ferrite decreased with increasing nickel content; this is accompanied with an increase in the region of Microstructure and Mechanical Properties of ASTM CA6NM steel is widely used in the manufacture of hydraulic turbines metallic parts,due to its resistance to corrosion and cavitation damage,combined with good weldability and fatigue properties.However,welding of this type of steel is complex and to ensure a minimum residual stress after welding it is necessary perform a post welding heat treatment (PWHT) of the part. results for this questionFeedbackMICROSTRUCTURE AND MECHANICAL PROPERTIES OFMICROSTRUCTURE AND MECHANICAL PROPERTIES OF A SIMILAR T24 STEEL WELDED JOINT AFTER SERVICE The material under investigation was a welded joint made of 7CrMoVTiB10-10 (T24) steel after 36,000 hours of use at the temperature of 540°C and pressure of 27 MPa.The test samples for the study were taken from a membrane wall of a USC steam boiler.
