Dear Experts Good Day to all,
I want to Clarify Stress relieving & PWHT . In Industry and generally talking and refering the books both words are used interchangeably.
My point of view stree relieving is applicable to the part which are undergone Hot/Cold working Examble like Dish Head,rolled products etc , PWHT is applicable to the welded part , Holding the temperature below the Tempering temperature to relieve stress to few hours depends on Code/End use requirements.
Any one can explain temperature of stress relieving , PWHT and any terminology of this two.
Any one can define the carbon Manganese steels & where we find the list of this materials, ABS Gr EH36 material fall in this catagory & If we fabricate EH36 material more than 50 mm thick full penetration weld followed AWS D1.1 code need to PWHT,Client nothing specified .
Thanks in Advance
