HL surface is the most common surface among stainless steel surfaces. It is also usually called brushed plate or hairline plate. Hairline plate means a brushed plate formed by hitting hair-like filaments on the surface of stainless steel. , this kind of silk pattern is generally relatively fine, and the quality of the raw material itself will directly affect the effect of hair lines. Hairline board is the most common surface processing of stainless steel. It can generally be used in elevators, lifts and other areas where the surface requirements are not very high.
The No4 surface is rotated by a polishing machine. The stainless steel surface can be polished under the rotation force. Compared with the HL surface, the No4 surface has the effect of shorter polished hair lines. This method is now used for polishing. It can generally be used in interior decoration and kitchen decoration. This kind of processing is the most widely used method in stainless steel polishing processing.
Mirror processing has more precise surface requirements than the first two types of processing. It requires special polishing materials for grinding, usually using a grinding wheel, and the rotation speed of the grinding wheel must be controlled. When the surface is rough, many times of grinding are usually required. Only in this way can the mirror effect be formed. The quality and usage of the grinding wheel itself will affect the grinding effect. After grinding, it can generally form a relatively beautiful mirror effect. This kind of mirror stainless steel plate can generally be used in building decoration, restaurants, and hotel entrances. It is beautiful and durable.
Because stainless steel is stronger than ordinary materials, higher pressure is required when stamping and shearing, and when the gap between the knives is accurate, shearing and work hardening will not occur. When gas cutting must be used, it is best to use plasma or laser cutting. Or during arc cutting, the heat-affected zone is ground and requires heat treatment.
Bending processing
Stainless steel plate bending
The stainless steel plate can be bent to 180°, but in order to reduce surface cracks, the radius is preferably 2 times the thickness. The thick plate gives 2 times the thickness along the rolling direction and 4 times the thickness when bent along the vertical direction of rolling. The radius is necessary, especially during welding, to prevent surface cracks in the weld zone and thus machining cracks.
Stainless steel plate welding
Before welding, rust, oil, water, paint, etc. that are harmful to welding should be thoroughly removed, and welding rods suitable for the steel type should be selected. The spot welding time interval is shorter than that of carbon steel spot welding, and a stainless steel brush should be used to remove welding slag. After welding, in order to prevent local corrosion or strength reduction, the surface of the stainless steel plate should be polished or cleaned.
