S690QL application stainless steel

The yield strength of S690QL application A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.

S690QL application, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of S690QL application, Chinese grade 45 steel depends on its various properties. S690QL application, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like S690QL application, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
