Two-way steel, pickled and passivated
Thread Content
What are the differences between the pickling and passivation of super duplex steel plates and those of stainless steel? I heard it’s because a different acid is used, which makes it more expensive. Please, an expert, explain in detail.
Can you explain it clearly? For example: what grade? What are the process requirements for treatment? Is there a salt spray test after passivation? Is welding used: What welding process? Treat the weld or the surface? What workpiece?
Hello, material grade: SA-240 S32750. Inspection is carried out using the blue dot method after passivation. Welding method for the container: plasma welding. Treatment area: all interior and exterior surfaces of the container. Object of treatment: the container body itself.
