The invention discloses a welding method for 10CrMo9-10 steel. The method comprises the following steps of:S1), machining a welding groove to obtain an X-shaped groove, milling a piece to be welded by using an edge milling machine, wherein the groove angle is 70 degrees, cleaning the groove and parts in the ranges of 25mm on two sides of inner and outer walls of the groove until metal luster
Effect of micro-phase electrochemical activity on the Feb 01, 2020 · The Q355NHD steel was mainly composed of polygonal ferrite (F) and pearlite (P), with P showing an obviously banded distribution (Fig. 2). Further observations revealed that the contents of F and P in steels Q355NHD and Q450NQR1 were different.
Effect of micro-phase electrochemical activity on the The electrochemical behaviors of micro-phases in three types of weathering steel (Q355NHD, Q450NQR1, and Q460q) were characterized by capillary microelectrode techniques (micro-phase potentiodynamic polarization, micro-phase electrochemical impedance spectroscopy, and micro-phase linear polarization) and the scanning vibrating electrode technique.
