What is multiphase steel?

Multiphase steel such as DP (dual phase), TRIP (TRansformation Induced Plasticity) and CP (Complex Phase) steel can be produced either directly from the rolling heat or by employing an additional heat treatment, usually after cold rolling. The latter is the route usually used to supply the automotive industry.See all results for this questionWhat is high strength low alloy steel?High Strength Low Alloy (HSLA) Steel HSLA steels were originally developed in the 1960s for large-diameter oil and gas pipelines.
