Polishing method of astm a479 316l stainless steel hexagon bar
There are three types of polishing for astm a479 316l stainless steel hexagon bar. Let’s introduce them below:
The disadvantages of high brightness are high labor intensity, serious pollution, messy parts cannot be processed, and their luster cannot be unified. Mechanical polishing: the flatness of the processed parts is good. The luster does not last long and becomes dull and rusty. More suitable for processing simple parts, medium and small products
Chemical polishing: low investment in processing equipment, the ability to throw away messy parts, fast speed, high efficiency, and good anti-corrosion properties. Its disadvantages are poor brightness, gas leakage, ventilation equipment required, and difficulty in heating. It is suitable for processing small batches of messy parts and products with low brightness requirements for small parts.
Electrochemical polishing: long-lasting mirror gloss, stable technology, less pollution, low interest, and good corrosion resistance. It is suitable for mass production and is mainly used in high-end products, imported products, and products with tolerances. Its processing technology is stable and the operation is simple.
When processing astm a479 316l stainless steel hexagon bar, there is a process to polish the stainless steel hexagonal bar. Polishing technology is a very important step in the processing of stainless steel profiles. This process is related to the lubrication, durability, anti-corrosion and other characteristics of stainless steel! Now in the stainless steel material processing technology industry, due to different types of steel, the polishing techniques used are also different!
Although general polishing technology has the advantage of high brightness, it also has many shortcomings, such as higher labor costs, contamination, and other parts that are too complicated to be processed.
The parts after mechanical polishing have higher flatness. However, the gloss time will not be very long, and phenomena such as rust and darkening may occur.
The advantages of chemical polishing are low processing equipment cost, the ability to handle messy parts, good anti-corrosion performance, and high speed and efficiency. The disadvantage is that the brightness is low and gas is generated, so ventilation equipment is required to exhaust air, and it is difficult to heat. Suitable for a small amount of debris, other smaller parts are not very bright
The advantages of electrochemical polishing are that the surface is very shiny, it lasts a long time, there is no pollution, the processing cost is not high, and it has good anti-corrosion properties. Suitable for mass production and processing. Mainly used on higher-end products and imported products.
