We have an application where sheetmetal assembly is processed in a furnace at about 1200°C. In this assembly we are using normal carbon steel fasteners and we feel that after the thermal cycle in completed, the fasteners will loose its physical properties especially hardness, tensile strength etc.
Can any one suggest a better carbon steel that should be used which will have mechanical properties desired for fasteners even after subjecting to the thermal cycle. Fastener used are generally M6, M8, M10 fine metric threads and thermal cycle is - heating to 1200° C gradually in about 1 hour then subjected it to the same temp for about 1 hour then gradual cooling for about 2 hours. Entire process is done in hydrogen reducing atmosphere.
Thanks to all the replies in advance.
