At 1000 Deg F, steel will have lost 80 to 90% of it's strength, or of it's ability to support a strucrural load. The strength of structural steel begins to deteriorate at temperatures above 650 Deg F. gatorbait Â· 10 years ago.
Why Welding Problems Occur. Free-machining steels with sulfur and phosphorus have relatively poor weldability because cracks can form during the final stages of weld solidification. The cracks arise from the presence of liquid MnS and phosphorous compounds at the weld metal grain boundaries.f one of these steels must be welded, the fabricator can try using low-hydrogen electrodes with a basic slag system. The weld metal's low-hydrogen characteristics will reduce the formation of hydrogen sulfide porosity, and the basic slag system reduces the weld metal's sulfur and phosphorus content.
