    high temp properties for SAE 4140 - Mechanical

    Mar 18, 2005 · Yeah, conservative IvyMike, is a safe play when risk outweighs probability of success. I would be more worried of creep at an elevated temperature since material strength drops significantly at 250-ish C. Although a common steel alloy, 4140 has it's limitationseven in the oil field! Interesting application though. Good luck with it! levated-Temperature Characteristics of Engineering carbon steel, but they can be more highly stressed because the molybdenum addition increases short-time tensile strength and reduces the creep rate for a given stress and temperature. If graphi­ tization under service conditions is probable, the maximum service temperature for carbon-molyb­ denum steels is about 450 'C (850 "F).
