How to purchase regular stainless steel plate

In sheet metal processing, machining process how to choose the right material, to today, stainless steel plate has existed for more than 90 years of history. Its surface is smooth, has good plasticity, toughness and mechanical strength, and can also resist acid, alkaline gas or solution corrosion. Stainless steel plate, mainly refers to the corrosion resistance of air, steam and water and other weak medium steel plate. For the uneven quality of the market, how should consumers choose? The following to follow the decoration home decoration network Xiaobian to learn to learn the purchasing skills of stainless steel plate.

One. Distinguish the material

The commonly used materials of color stainless steel plate on the market are 201, 304, 316 and other models, which are made by processing and coloring. Among these models, the best corrosion resistance is 316, and the worst is 201, the price difference is also relatively large. Therefore, some black merchants often use 201 with poor material to replace 304 and 316. Some will use water plating coloring process to replace vacuum ion plating coloring process, which makes many building decoration projects install stainless steel plate, surface color loss, rust and even fracture problems.

2. Surface coloring process

Stainless steel surface coloring process will affect the price of high and low, mainly water plating coloring process and vacuum plating coloring process, the former gives a person is not real, not exquisite feeling, like spraying up, will also produce waste water pollution, the price is low. The latter is relatively environmentally friendly and does not produce toxic or polluting substances.

Three. Look at the metal surface

Because the color stainless steel plate is mainly used for building decoration, it is very important for viewing. When the owners inspect the goods, they need to close the goods, carefully inspect and observe the surface to see if there is a color difference, as well as scratches, trachoma, peeling water marks and other problems.

Four. The quality of the film

After processing, usually in the color of stainless steel plate surface paste a layer of protective film, in order to ensure the surface finish, and can avoid hard objects scratch. Poor quality protective film, put for a long time, will appear powder phenomenon, difficult to tear, or tear on the surface will stick a lot of glue, difficult to look at. When inspecting goods, it is recommended to tear a large area to check the quality of the film, and after the installation of the decoration project, tear off the film as soon as possible, especially for outdoor decoration. The above information plays a relevant role.

What are the characteristics of stainless steel processing

Stainless steel processing manufacturers believe that the mechanical properties of investment cast stainless steel are higher than cast iron, because of its high melting point, easy oxidation of molten steel, poor liquidity of molten steel, large shrinkage rate, volume shrinkage rate of 10-14%, line shrinkage rate of 1.8-2.5%. In order to prevent defects such as insufficient pouring, cold isolation, shrinkage cavity and porosity, crack and sand adhesion of steel castings, more complex technological measures should be taken than that of cast iron:

Stainless steel processing characteristics

Stainless steel processing characteristics Stainless steel processing characteristics are: high cutting temperature, cutting is not easy to break, easy to combine, cutting force, serious hardening, tool wear. Stainless steel refers to alloy steel with chromium content greater than 12% or nickel content greater than 8%. This steel has China's certain corrosion resistance in atmospheric or corrosive environmental media, and can be used at a higher operating temperature (> 450℃). It has very high strength.
