  • PATENTING :
    Heating to above the critical and cooling in air or molten lead at a temperature of about 700° F.

  • PERCENTAGE OF ELONGATION :
    The percentage of increase in length of a tension test specimen after rupture.

  • PERCENTAGE REDUCTION OF AREA :
    The percentage of decrease of cross-sectional area of a tension test-specimen after rupture.

  • PICKLING :
    Removing scale by immersion in a dilute acid bath.

  • PLATE :
    Carbon steel plate comprise that group of flat rolled finished steel products within the following size limitation:

  • PREHEATING :
    (1)  A general term used to describe heating applied as a preliminary to some further thermal or mechanical treatment.  (2)  A term applied specifically to tool steel to describe a process in which the steel is heated slowly and uniformly to a temperature below the hardening temperature and is then transferred to a furnace in which the temperature is substantially above the preheating temperature.

  • PROCESS ANNEALING :
    Heating to a temperature below or close to the lower limit of the critical and then cooling.

  • PROPORTIONAL LIMIT :
    See Elastic Limit.

  • PSL :
    Product Specification Level.

  • PSPE :
