In order to compare direct quenching with conventional quenching, two pre-quench austenite states were studied: a thermomechanically rolled, ,non,-recrystallized, pancaked austenite grain structure and a recrystallized, equiaxed grain structure. ,Quenched, and ,quenched,-and-tempered microstructures were studied using FESEM and FESEM-EBSD.

Flat products made of steels for pressure purposes. Weldable fine grain steels, ,quenched, and tempered. These are the ,quenched, and tempered pressure vessel steels with a range of Q, QH, QL1 and QL2 after the normal P designation and the yield strength. So P355Q, P355QH, P355QL1 and P355QL2. Etc. We don’t stock any of these. BS EN 10028-7:2007.

In the case of the direct ,quenched, (DQ) material, tempering led to a notable increase in the size of the grain boundary carbides. Prior austenite grain size and effective grain size after quenching were larger in the case of reheated and ,quenched, material (RQ). Tempering had no effect on effective grain size.

The hardness distribution of the non-quenched steel is more uniform than the corresponding quenched and tempered steel with the similar strength level, since the former is not so sensitive to the

Austempering - Wikipedia
Austempering - Wikipedia

Austempering, is heat treatment that is applied to ferrous metals, most notably steel and ductile iron.In steel it produces a bainite microstructure whereas in cast irons it produces a structure of acicular ferrite and high carbon, stabilized austenite known as ausferrite.It is primarily used to improve mechanical properties or reduce / eliminate distortion.

25/2/2019, · ,Plate, quenching is the recommended method for heat treating in small batches. That should provide cooling rates significantly faster than required while helping to maintain flatness D3 steel – 2.0C-0.3Mn-0.3Si-12.0Cr [5] – Despite the high Cr, with high C and no Mo D3 is sometimes called an oil hardening steel, needs to be cooled in about 300 seconds
