Prevention of delayed cracking of iron based hardfacing

Longitudinal and transverse cracks were observed to occur on the surface of Norem hardfacing welds for a period of time after welding.The welds were mainly cracked by hot cracking.To prevent the weld from cracking,a hammer peening process was employed to mitigate its tensile stress.sp.info Author Tonye Alaso Jack,Reza Pourazizi,Enyinnaya Ohaeri,Jerzy Szpunar,Jiming Zhang,Jinbo QuPublish Year 2020Defects / Hydrogen Cracks in Steels - Identification - TWIHydrogen cracking may also be called cold cracking or delayed cracking.The principal distinguishing feature of this type of crack is that it occurs in ferritic steels,most often immediately on welding or a short time after welding.In this issue,the characteristic features andsp.info Low-nickel austenitic stainless steel - Outokumpu OyjThe invention relates to a low-nickel austenitic stainless steel with high resistance to delayed cracking and the use of the steel.The steel contains in weight % 0.02-0.15% carbon,7-15% manganese,14-19% chromium,0.1-4% nickel,0.1-3% copper,0.05-0.3% nitrogen,the balance of the steel being iron and inevitable impurities,and the chemical composition range in terms of the sum of carbonsp.info Delayed Cracking - an overview ScienceDirect TopicsFor welding bainitic and martensitic grades,the management of the thermal cycle allows one to avoid the hydrogen delayed cracking,solidification cracking issues and the proper microstructure formation,avoiding unwanted softer or brittle phases.In the following figures are reported exemplary heat cycles during the welding fabrication for a bainitic steel,a martensitic,and a 9%Cr cast steel
