Stainless Steel Processing Technology

Stainless steel processing equipment classification is divided into cutting equipment and surface treatment equipment, cutting equipment is divided into open set. In addition, from the thickness of stainless steel to points, there are hot and cold rolling processing equipment points. Hot cutting equipment mainly plasma cutting, laser cutting, water cutting and so on. From the stainless steel products to points, generally divided into stainless steel seamless pipe and stainless steel welded pipe.

Original surface: NO.1 Hot-rolled surface subjected to heat treatment and pickling. Generally used for cold-rolled materials, industrial tanks, chemical industrial devices, thicker thick by 2.0MM-8.0MM.

Blunt surface: NO.2D cold after the heat treatment, pickling, the material is soft, the surface was silver white luster, for deep drawing processing, such as automotive components, water pipes and so on.

Matte: NO.2B After cold rolling by heat treatment, pickling, and then finishing the surface to make the surface of the bright light. As the surface is smooth, easy to re-grinding, so that the surface is more bright, widely used, such as tableware, building materials. With the improved surface finish of mechanical properties, almost all applications are met.

Coarse sand: NO.3 with 100-120 grinding belt grinding out of the product. Has a better gloss, with a discontinuous coarse pattern. Used for building interior and exterior decoration materials, electrical products and kitchen equipment.

Fine sand: NO.4 Grinding out the product with particle size 150-180. Has a better gloss, with a discontinuous coarse grain, stripes than NO.3 fine. For bath, building interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.

Bright: BA is subjected to bright annealing after cold rolling and passed through flattened products. Excellent surface gloss, with high reflectivity. Like a mirror surface. For household appliances, mirrors, kitchen equipment, decorative materials.

In the field of construction applications, the surface treatment of stainless steel is important for many reasons. Corrosive environment requires a smooth surface because the surface is smooth and easy to scale. The deposition of dirt can cause rusting of stainless steel and even corrosion. In the spacious hall, stainless steel is the most commonly used material of the elevator decorative plate, although the surface of the fingerprint can be wiped off, but the impact of beauty, so the best use of the appropriate surface to prevent leaving fingerprints. Hygiene conditions are important for many industries, such as food processing, catering, brewing and chemical, etc. In these applications, the surface must be easily cleaned daily and often with chemical cleaning agents. Stainless steel is the best material in this area, and in public places, the surface of stainless steel is often mischievous, but one of its important features is the ability to clean them off, which is a remarkable feature of stainless steel over aluminum. The surface of aluminum is easy to leave traces, often difficult to remove. Clean the surface of stainless steel should be cleaned along the stainless steel lines, because some of the surface processing lines are one-way. Stainless steel is most suitable for hospitals or other areas of hygienic conditions, such as food processing, catering, brewing and chemical, not only because it is easy to clean daily, but also use chemical cleaning agents, but also because it is not easy to breed bacteria The The test shows that the performance of stainless steel in this respect is the same as that of glass and
ceramics.
