Usman K asked:


I would like to get information for the products (other than Spectrometer, and physical laboratory testing through reactions). available in market that allow to do a chemical analysis of mild steel. i would be interested in finding the following elements manganese, silicon, nickel, chromium, aluminium, molybdenum and copper. Also not forgetting the ‘impurities’ such as phosphorous and sulphur.
