The superiority of 443 stainless steel as a kitchenware

443 stainless steel has many characteristics. Compared with 304 stainless steel, food utensils have more advantages:

1. 443 stainless steel increases the chromium content by 21%, making it comparable to 304 stainless steel;

2. 443 stainless steel does not add nickel element, and the cost is relatively low;

3. Since 443 is iron stainless steel, it has magnetic conductivity;

4. 443 stainless steel's thermal conductivity is also better than 304 stainless steel. As a pot product, it is more efficient than the 304 stainless steel pot. Anti -corrosion, delay the aging of materials, and improve the life of pot kitchen utensils.


443 Stainless Steel's requirements for production molds:

Because the yield strength of 443 stainless steel is high and the tensile strength is lower than that of 304 stainless steel, it is easy to crack at the R corner with a large cut stress. , Appropriately increase the R horns and pores. In the actual production process, the production of most of the lack of swelling utensils can be universal 304 molds.

How to estimate whether 443 stainless steel can successfully replace 304 in micro expansion and micro -inflation products

After the actual test, according to the shape and size of different products, when the expansion line of most products is deformation within 8-15%, the strength and extension of stainless steel materials are safe. Because the larger the product deformation, the greater the stress produced by the lattice distortion, the product with a large deformation should be chosen as little as possible.

Compared with 304 stainless steel, how to adjust the polishing process when applying 443 stainless steel?

Because 443 is iron stainless steel, the sliding line is obvious after stretching and processing, so its surface is rough than 304 stainless steel after stretching, which makes it difficult to polish when polishing. Crude sand polish and increase the speed of polishing raids to solve it, but the polished 443 stainless steel surface is significantly better than 304.

443 Stainless Steel Products before finished packaging

In actual processing, it will occasionally find the rust of sand -light surface products. After detection and analysis, it is found that the cause of rust is actually not very clean after polishing. Fortunately, clean the product before the finished packaging.
