Production process of stainless steel for subway handrails

Stainless steel processing refers to the process of shearing, bending, bending, welding and other mechanical processing of stainless steel to obtain stainless steel products required for industrial production. In the process of stainless steel processing, a large number of machine tools, instruments and stainless steel processing equipment are needed. Stainless steel processing equipment is classified into shearing equipment and surface treatment equipment, and shearing equipment is divided into flattening equipment and slitting equipment. In addition, according to the thickness of stainless steel, there are also cold and hot rolling processing equipment. Thermal cutting equipment mainly includes plasma cutting, laser cutting, water cutting, etc.

Stainless steel surface finish grade

Original surface: NO 1. Surfaces subject to heat treatment and pickling after hot rolling. It is generally used for cold rolling materials, industrial tanks, chemical industrial devices, etc. The thickness is from 2.0mm to 8.0mm.

Blunt face: NO After 2D cold rolling and heat treatment and pickling, the material is soft and the surface is silvery white luster, which is used for deep stamping processing, such as automobile components, water pipes, etc.

Fog surface: NO 2B cold rolled, heat treated, pickled, and then finish rolled to make the surface moderately bright. Because the surface is smooth, it is easy to regrind, making the surface more bright and widely used, such as tableware, building materials, etc. After surface treatment with improved mechanical properties, it can be used for almost all purposes.

Coarse sand NO 3. The product is grinded with No. 100-120 abrasive tape. It has better glossiness and discontinuous coarse lines. It is used for building interior and exterior decoration materials, electrical products, kitchen equipment, etc.

Fine sand: NO 4. The product is grinded with 150-180 abrasive belt. It has better glossiness, discontinuous coarse lines, and the fringe ratio is NO 3 Fine. It is used for bath, decoration materials inside and outside buildings, electrical products, kitchen equipment, food equipment, etc.
