S690Q material equivalent ms cs seamless pipe tube price

S690Q material equivalent surface cracks refer to the linear cracks on the surface of S690Q material equivalent, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: S690Q material equivalent surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

Q960 steel plate is a high strength structural steel which is delivered in the state of quenching and tempering. Applicable thickness is not more than 150 mm. S690Q material equivalent, Q960 steel plate is widely used in the manufacture of bridges, buildings, cranes, shipbuilding, vehicles and large structural parts. Q960 quenched and tempered steel is smelted by oxygen converter or electric furnace.
