S690QL equivalent ASTM steel pipe components

ASME S690QL equivalent ASTM delivery status: thickness ≤40, hot rolled or normalized; thickness ＞40, normalized
According to the different tensile strength of the material, ASME SA204 steel is divided into three strength grades: A, B, and C, namely SA204GrA, SA204GrB, and SA204GrC. The maximum thickness of steel plates corresponding to these three grades is limited to:
SA-204A large plate thickness does not exceed 150mm
SA-204B large plate thickness does not exceed 150mm
SA-204C large plate thickness does not exceed 100mm

Will S690QL equivalent ASTM, stainless steel rust? Under normal conditions, stainless steel will not rust. It has a great relationship to the composition of stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon and so on elements. Scientists have found that the more uniform the internal structure of steel, the closer the various components are linked, and the more difficult it is for corrosive substances to invade. In addition, a layer of oxide protective film is attached to the surface of stainless steel, which is just like wearing armor on steel, it is not easy to rust.

At present, there are many cutting methods for S690QL equivalent ASTM steel plate cutting, such as common flame cutting, plasma cutting and laser cutting. Different cutting methods correspond to different cutting tools and cutting equipment. Therefore, based on this point, we can know that the answer to this question is yes, that is, there are many tools and equipment involved in S690QL equivalent ASTM steel plate cutting, You can choose according to the cutting mode.
