First of all, we need to know what is pickling: the method of using acid solution to remove oxide scale and rust on the surface of DIN 2445-1 ST52.4 seamless steel pipe is called pickling. Acid for pickling includes sulfuric acid, hydrochloric acid, phosp

Comparing EN 10297-1 C45 seamless steel tube with solid stainless steel plate such as round steel, when the tensile strength and torsion tensile strength are the same, the net weight is relatively light. It is a kind of stainless steel plate for social an

Intergranular corrosion of DIN 1630 ST44.4 seamless steel pipe. It refers to corrosion along dislocations, which destroy the connections between crystals. This kind of corrosion is hazardous, it will make DIN 1630 ST44.4 seamless steel pipe brittle or los

Local pitting corrosion. It refers to a form of corrosion damage that occurs in part of the metal surface of DIN 1630 ST52.4 seamless steel pipe. After the occurrence of crevice corrosion, it can develop rapidly to a deep trend, through DIN 1630 ST52.4 se
