About stainless steel special-shaped, I believe it is not unfamiliar to everyone, because it can be seen everywhere in our lives. The appearance of stainless steel special-shaped bending processing parts is beautiful and artistic. After planing, shearing and bending, the color stainless steel plate is processed into door cover, stainless steel Product screen engineering decoration brings a lot of convenience to our lives. Stainless steel special-shaped bending processing is not only anti-corrosion, anti-oxidation, environmental protection, and has the value of recycling and remanufacturing. So what are the main advantages of stainless steel special-shaped bending processing? Let’s get to know it together.

1. Advantages of stainless steel special-shaped bending processing


1) Stainless steel special-shaped does not fade without fading

The color of stainless steel colored products is the physical reaction of the finished product in a high vacuum environment. The color of high-temperature ionized inert gas is deposited on the surface of the product. The adhesion is 100 times that of ordinary paint. It is scratch resistant and can not fade and fade in indoor environments.

2) Does not change the original surface gloss of stainless steel

Although the common paint process has many colors, it will cover the texture or gloss of the original stainless steel surface, but the plating color will not only not, even the product gloss after plating will be more obvious and crystal clear.

3) Stainless steel does not rust or oxidize

Ordinary iron products will rust even if it takes too long to paint; ordinary aluminum and copper products will be oxidized after a long time. Stainless steel does not. The surface of 304 stainless steel has a colorless and transparent chromium oxide protective layer, which is like a cling film that is invisible to the naked eye. It prevents water vapor and oxygen in the air from corroding the stainless steel surface, so it will not rust. Oxidation, the protection effect of stainless steel is better after the plating process.

4) Stainless steel fireproof and anti-corrosion

Generally, wood products have a low fire point, which is easy to catch fire and have safety hazards. Therefore, it is recommended to use wood as little as possible for decoration. In addition, ordinary wood products will rot when exposed to water, and even bugs may crawl out of the wood. Stainless steel is rolled in a blast furnace, so it is fireproof. In addition, the rust resistance of stainless steel ensures anti-corrosion.

5) The hardness of stainless steel is good without cracking

There are usually many designs that use art glass as a decorative product, and it is also used as a screen, but it cannot withstand collisions, and even the glass will explode, which poses a great safety hazard. Stainless steel is not the same as tough and extremely tough steel is the material of choice for all cutting tools.

2.The key points of special-shaped bending of stainless steel plate

Due to the high yield point of stainless steel, high hardness, and remarkable cold work hardening effect, the characteristics of stainless steel plate are as follows when bending:
1)The special-shaped processing of stainless steel plate has a lower thermal conductivity than ordinary low-carbon steel and lower elongation, which leads to a large deformation force.

2)Compared with carbon steel, the special-shaped processing material of stainless steel plate has a strong rebound tendency when bending.

3)Compared with carbon steel, the special-shaped processing of stainless steel plate has low elongation. The bending angle R of the workpiece during bending should be greater than that of carbon steel, otherwise cracks may appear.

4)Due to the high hardness of stainless steel special-shaped machining, the effect of cold work hardening is significant. Therefore, when selecting bending tools, select tool steel with heat treatment hardness above 60HRC, and its surface roughness is an order of magnitude higher than that of carbon steel bending tools.

According to the above characteristics, generally speaking, if the unit size is thicker for stainless steel plate processing, the greater the bending force we need, and as the thickness of the stainless steel plate increases, when choosing the bending equipment The intensity should also be greater. The greater the tensile strength, the smaller the elongation, the greater the bending force required, and the greater the bending angle. Compared with carbon steel with the same thickness of stainless steel, the bending angle is larger. Special attention should be paid to this point. Otherwise, bending cracks will occur, which will affect the strength of the workpiece.

3. Factors of springback in special-shaped bending of stainless steel plates

1) Hardness of special-shaped bending of stainless steel plate: the greater the hardness, the greater the springback.

2)The ratio of material thickness to material thickness of the bending radius during special-shaped bending of stainless steel plates: the greater the ratio, the greater the springback.

3)In the special-shaped bending process of stainless steel plate, the rebound of SUS301 is greater than that of SUS304. Under the same circumstances, the rebound of 304 is 2 degrees smaller than that of 301.

4)There are also differences in the forming methods of special-shaped bending of stainless steel plates. The springback of one-step molding is greater than that of multiple moldings.

5) How much is the difference in bending of the stainless steel plate, and how much is the difference, and it is necessary to pay attention to the rebound of the angle and the radius of the rebound. The specific conditions are analyzed in detail.
