Temper embrittlement, a phenomenon that has troubled refiners and chemical producers for decades, has been extensively studied with no single proposed model able to reliably predict embrittlement outside of its own data set. Our experts are well acquainted with the literature on this topic and are hard at work determining the best solution for safely managing embrittled pressure equipment.

Long-term exposure to high temperatures, typically between 650°F (343°C) and 1070°F (576°C), is known to cause a reduction in toughness in low-alloy steels. The reduction in toughness is known as temper embrittlement and represents a metallurgical change experienced by the steel. (EEPub134)
