The choose methods of stainless steel plate

We often use stainless steel plates for building and family decoration. Stainless steel plate is a kind of material with strong anti-corrosion, so it has been widely used, but when we buy inferior products, its material Corrosion resistance is also very bad, so we need to pay attention to the selection method when buying stainless steel.
How to choose stainless steel plate?
Nowadays, stainless steel plates are indispensable in the construction and decoration. The stainless steel plate is a steel plate with good corrosion resistance. So many steel plate manufacturers are increasing the productivity of stainless steel plates, but there are also some unscrupulous traders.
1, Before the selection of stainless steel plate must take into account the use of stainless steel and the use of the environment. Such as: decorating the general use of welded pipe, fluid transport generally use seamless pipe, medical or kitchen to use sanitary stainless steel plate, pressure using thick-walled pipe; More than 316 materials are generally used in acid-alkaline areas or coastal areas.
2, In the selection of steel pipe must be determined material standards. Take 304 material as an example: a, from the price analysis, if the 304 stainless steel plate is even lower than the general price of the material on the market 301, to be carefully identified, it is likely that the other material posing; b, identify whether the surface of the pipe hit the seal Material “304”, and to obtain the manufacturer’s quality certificate as a certificate;good quantities of samples can be sent to the national authoritative testing center Component testing.
3, To see the color of the surface and the inner of the tube is bright and smooth, the thickness is uniform or rough. In general, the welded pipe basically does not need to be inspected, and the seamless steel pipe is produced by cold drawing or hot rolling. In the production process, improper operation may easily lead to uneven thickness, cracks on the pipe surface, etc., while the surface roughness is generally seamless. No polishing treatment, no special requirements on the appearance does not affect the use.
4. When purchasing, select the excellent product that is assessed by the Bureau of Quality and Technical Supervision. The long-term use of witnesses and good word of mouth among customers is the most direct and effective method of purchasing.
Therefore, we must remember when buying stainless steel plate, we can not blindly pursue the low price of stainless steel plate and ignore the quality, only the high quality stainless steel plate can make us more comfortable to use.
