ASTM A209 T1 seamless steel tube magnetic particle inspection or penetration inspection, can effectively find surface cracks, folds, double skin, hair lines, pinholes and other surface defects. For ferromagnetic materials, magnetic particle detection meth

See for steel composition of ASTM A333 Gr.10 steel tube, whether it is uniform enough. Because of the inferior ASTM A333 Gr.10 steel tube, there are more impurities in the pipe, and the density of steel is too small. As soon as we look at the cross sectio

ASTM A333 Gr.10 seamless steel tube is boiled in boiling water for 30-60 minutes before quenching, which can eliminate 15% to 25% of the quenching internal stress and stabilize the residual austenite, and then undergo conventional cooling treatment at -60

Seamless steel pipe has a hollow section, a large number of fluid pipeline, such as the transportation of oil, natural gas, gas, water and some solid materials pipeline. Seamless steel pipe is mostly medium and high carbon alloy steels. After quenching, s
