Stainless steel materials, if used properly, will bring us a lot of useful help, but if there is a problem with the product, it will not only affect our use, but also affect the performance. Today we have a ISO9001 Air Filter surface bubble problem to explain the solution.

If the stainless steel filter surface is normal, it should be corrosion resistant and surface contamination or other similar surface contamination can be easily removed. The main cause of bubble solidification is that the molten steel contains a large amount of gas. When the molten steel solidifies, the gas is discharged to form bubbles. The bubbles in the vicinity of the outer layer of the billet become subcutaneous bubbles, which are vertically arranged in a honeycomb shape on the surface of the billet. Usually, the bubbles in the billet after rolling of the Pre-Filter Air Filter Replacement Fleetguard can be welded, but some subcutaneous bubbles are close to the surface. When heated, when the surface of the billet is oxidized or burned, the subcutaneous bubbles are exposed, oxidized, and unable to be welded, thereby causing cracks.
