High Temperatures - Higher Stress Applications
|
|
Minimum 0.2% and 1.0% proof
stress and some tensile strength values at elevated
temperatures are presented for pertinent steels from
Euronorm 88-86 and 95-79, from British Standards and
from DIN/SEW400. ASME Boiler and Pressure Vessel Code
1992, Section II Part D has data for some UNS designations.
Above 550°C, the strength of austenitic Cr-Ni type
steels become very time dependent as illustrated by
the estimated average stress values producing 1% strain
or rupture in 10,000 or 100,000 hours (based on Euronorm
95-79 and BS 1501 part 3.1990). Allowable design stresses
may be found in:
BS 5500 Specification for unfired fusion welded pressure
vessels ASME Boiler and Pressure Vessel Code, 1992 Section
II Part D, tables 1A, 1B, 2A, 2B.
Absence of quoted values above 250-300°C for ferritic,
martensitic and duplex steels reflects their susceptibilities
to embrittlement at higher temperatures.
