    If a sample is direct-quenched into the region below the e solvus but above the G.P. solvus (Figure ), no 0" forms. However, if a sample is direct-quenched below the G.P. solvus and then up-quenched into this region and aged, 6" forms and its distribution is a function of the size distribution of G.P. ones present before the sample was up. Piña says the direct-quenched heavy steel also has superior surface quality compared to steel from traditional quenching methods. Ruukki suggests using its new steels for various parts including. Hot-Tap field welding of high-strength pipeline steels under process conditions, with an emphasis on the advantages brought by modern low-carbon steels.
