Dear Mr.Goswami I have a component, material ASTM A 514Gr F and made by "casting" due to complex design. The thickness is 100mm. After casting, it has been given only a annealing treatment by the casting manufacturer ( @900 degrees ). I dont understand why it was not quenched and tempered. The service temperature of this component is at room temp. Now a part of this casting has broken and i want to weld it. I have selected E309L electrode. Kindly let me know the PREHEAT and INTERPASS Temperature for welding this 100mm thick A514 Gr F. By calculations i have got preheat temp as 125 degrees C as there is no restraint and i will be using a basic coated electrode. Also i realise that no PWHT is required. Kindly advise..

Hello Srinivas, Attached are the compositions and the mechanical properties of all grades of ASTM A514.The back to back grades adopted for boiler and pressure vessels are classified under SA -517. You may see the comparative descriptions for all the grades concerned. Since these steels not used for common fabrication work, one has to compare all the properties then only look for substitution. You may not get the exact equivalence and replacement , if so is intended. If you have any specific issue with this steel feel free to drop a lone. Thanks. Pradip Goswami,P.Eng.IWE Welding & Metallurgical Specialist & Consultant Ontario,Canada. Dear Srini From I did in past, it is allowed to substitute material when the following requirement/number of factors are met to the original mat'l (I notice this depends on Client Spec). 1. Carbon content 2. Sulfur composition 3. Phosphor composition 4. Mechanical properties i.e. yield strength, tensile strength, elongation and etc 5. Carbon equivalent (shall not exceed CEQ maximum) or PCM max 6. Impact test (if required by Client) Have a nice day -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents. -- To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents.
