Dear sir I have a question,, Hot working refines grain structure and cold working distorted grain structure then why surface finishing is better in cold working??
In Hot Working there is scale formation on the surface of workpiece due to high temperature but in cold working, there is no scale formation on the surface of workpiece..... That'shwhy cold working has better surface finish than hot working.
Sir ek grade and standard pe video banaye grade like bearing grade,SS , Carbon steel,alloy steel & standard like ASTM, ASME, DIN, BS ,CSK, API, IS Or sir NDT ke bare me...
Aap jaise log teacher kaise ban jate hai, thik se likhe to hai jo achha se smjh aaye kisi ko aur padha rahe hai, aap ke wajah se bachcho ka bhavishy kharb ho jaataa hai, please 🙏 sir aap apna ✍️writing thik kre pehle , thoda saf safai likhe taki student ko smjh aaye,,,, ,,,, " dhanyavaad "
