Common thicknesses of sheet metal
Sheet metal part thickness standards are different in each country, and the thickness of different plates is also different. We will introduce several aspects below,
so that we can further understand sheet metal.
Common sheet metal thickness standard analysis
1. Commonly used sheet metal thickness standards in China:
The commonly used domestic sheet metal thickness standards mainly include the following aspects: the general thickness of cold-rolled plates (steel plates, thin plates) is 0.4-4.0mm,
the general thickness of hot-rolled plates (steel plates, medium plates, deposition plates) is 4.5-22mm, stainless steel plates Thin plate (strip) generally has a thickness of 0.2-3.0mm.
Of course, these are just some common specifications, and the actual situation needs to be determined according to the specific use and process requirements.
Second, the international commonly used sheet metal thickness standards:
The commonly used sheet metal thickness standards in the world include the following areas: steel plate, thin plate, medium plate, deposited plate, aluminum plate,
stainless steel plate, etc. Standards include ASTM (USA), JIS (Japan), DIN (Germany) and other international standards. Taking ASTM as an example, the standard thickness of its
steel plate is 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 1.8mm, 2.0mm, 2.5mm, 3.2mm, 4.5mm, 6.0mm, 9.0mm, 12.0mm, 16.0mm, 19.0mm, 22.0mm, 25.0mm, when the thickness is more,
it needs to be realized through the corresponding processing technology.
2. Commonly used error standards:
A very important issue in sheet metal processing is error control. Errors generally include flatness errors, curvature errors and surface errors. Commonly used error standards are as follows:
millimeter series, foot series, scale series, etc.
3. Matters needing attention in the selection of sheet metal thickness:
1）It is necessary to select the appropriate thickness according to the actual application scenario;
2）The greater the thickness of the sheet metal, the higher the price, which needs to be balanced according to the budget and actual needs;
3）The selection and quality of sheet metal materials are also important factors affecting the selection of thickness;
4）The requirements of processing methods and techniques also require a specific evaluation of the thickness.
