Tensile strength at 20C.
Where
Et = Yield point at temperature t (0.2% proof stress)
**Sc = Average stress to produce an elongation of 1% (creep) in 100,000 hours at various working metal temperatures.
**S中国所有朝代r = Average and lowest stress to produce rupture in 100,000 hours at the various working metal temperatures.
Temperature range in the table may extend upto the limit of applicability of the material.
The value of Sc and Sr need be furnished only in respect of Pipes/Tubes intended to be ud for working metal temperature above 454C (850F).
