Common maintenance at five seating methods: stainless steel, stainless steel passivation solution can effectively protect the metal substrate, improve antirust ability, improve the resistance to salt fog test time, prolong the service life of the workpiece.
Second, the stainless steel electrolytic polishing liquid type belongs to the light formula, the speed of light, but also for stainless steel materials can achieve antirust antioxidant effect, strong commonality.
Only need three, stainless steel pickling passivation solution at room temperature soak can quickly reach silvery white bright stainless steel surface, with ultra high corrosion resistant ability, will generate complete in the surface of stainless steel, dense, not easy to damage the passivation film.
Four, in addition to scale pickling is solid solution heat treatment state delivery of seamless and welded stainless steel pipe manufacturing process indispensable one of the most common form, its main purpose is to remove the stainless steel tube inside and outside surface of the generated in the solid solution or annealing heat treatment scale.
Five, the soft acid purification to remove only hard to avoid in the process of manufacture, storage or transportation of iron ion and other heterogeneous metals and their salts fouling, nitric acid or citric acid does not contain hydrofluoric acid can be used for purification.
