The folding and cracking of the outer surface of the 904L stainless steel pipe is generally caused by poor steel, and is of course related to the rolling of steel ingots or continuous casting blanks to the tube blank. For example, when the tube blank is rolled, the metal is overfilled and the ear is rolled, and it is easy to cause linear folding by the next pass rolling. The main steel structure of 904L stainless steel pipe has scientific and reasonable structure, good plasticity and flexibility, high structural stability, and is suitable for building structures with large vibration and impact loads. It has strong resistance to natural disasters and is especially suitable for some earthquake-prone zones. Building structure. The surface of the Hastelloy tube product is treated with a matte and anti-oxidation process, and has a strong metallic texture, which is bright, elegant and fashionable. The patented technology combined treatment makes the combination of plastic and metal tight, and combines the advantages of various pipes in one body, and complements each other's defects.
