ASTM A312 201 Stainless Steel Square Pipe 1/2'' To 4 1/2'' and Rectangular Pipe
Storage: Pay attention to moisture, dust, oil, lubricating oil, as well as surface rust, or poor welding corrosion resistance.When water is immersed between the film and the steel substrate, the corrosion rate is faster than that without the film.Warehouse storage should be placed in a clean, dry and easy to open the air, to maintain the original packaging state, the stainless steel film should avoid direct light, film should be periodic inspection, if the film deterioration (film life of 6 months) should be replaced immediately, if the packing material when pad paper, in order to prevent surface corrosion should be immediately removed pad paper.
