The requirement for ASTM A217 Gr. WC9 castings for valves components like Body and Bonnet were Normalising at 920+/- 20 Deg. C and Tempring 780+/- 20 Deg. C The specification calls furnace shall be calibtated within +/-14 deg. C The Heat Chart shows minimum temperature for normalising 900 to 920 Deg. C, but maximum temperature 960-990 Deg. C Tempering 780+/-20 Deg. C is within limits and accepted. Casting having integral test bars, heat trated along with castings passed in chemical znalysis and mechanical properties. Since normalising maximum temperature is not meeting specification, where castings can be salvaged or renormalised and retempered to meet specification. Whether it will have affect on remechanical properties testing
