<p>1982: Creep-strength steel
</p>
From the mid-1970s to early 1980s, ORNL works with Combustion Engineering (now Alston Power Inc.) to develop the first creep-strength enhanced ferritic (CSEF) steel, Grade 91. The steel debuts in 1982. Grade 91 and subsequent CSEF steels become a worldwide standard for achieving high efficiency and safe and reliable performance.
