HAZ embrittlement is often caused by broken straight seam steel 16Mn, induced root cause catastrophic accidents. Partial embrittlement has two main regions Dafeng 16mn, ie, the heat-affected zone CGHAZ embrittlement 16mn seamless steel prices, is due to over-grown grains overheated zone and the formation of undesirable tissue caused by the multi-layer welding time CGHAZ another critical embrittlement, which is heated again before CGHAZ weld bead by subsequent two-phase region caused. This is done by adding a certain amount in the steel Ti, Nb micro alloying elements and control weld cooling rate to get the right t8 / 5 to improve toughness. With 16Mn straight seam reduce the carbon content of steel, welding reduced sensitivity to hydrogen induced cracking, in order to avoid cracking process measures needed to reduce the extent of damage reduced performance weld heat affected zone. However, due to the welding seam steel 16Mn straight through a series of complex physical and chemical non-equilibrium processes, which may cause defects in the weld zone, or the joint performance degradation 16mn, the main problem is the weld cracking and HAZ embrittlement problem.
