How to choose the material of the emulsifying pot?


The pot body material of cosmetic machinery vacuum homogenizing emulsifying pot is usually 316L stainless steel and 304L stainless steel. For cosmetic machinery, what is the difference between these two specifications of stainless steel? 


Stainless steel is suitable for use as an important corrosion-resistant material in the chemical, chemical fiber, fertilizer and other industries. In addition to the characteristics of atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions, it has excellent intergranular corrosion resistance, excellent work hardening, seawater equipment, papermaking and other production equipment, and acetic acid equipment. Its resistance to intergranular corrosion is good. 


316L stainless steel has a maximum carbon content of 0.03, which can be used in applications that cannot be annealed after welding and require maximum corrosion resistance. SUS316L stainless steel has better corrosion resistance than 304 stainless steel, and has good corrosion resistance in the production process of pulping and papermaking. performance. Moreover, 316 stainless steel is also resistant to the erosion of the ocean and the corrosive industrial atmosphere. 


In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to continuously act on 316 stainless steel, but when 316 stainless steel is continuously used outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and the above-mentioned temperature range can be used. Annealing in the temperature range of 1850-2050 degrees, then rapid annealing, and then rapid cooling. It has high temperature resistance, easy processing and high strength. 316L stainless steel does not require post-weld annealing treatment. 

316L stainless steel is added with Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and it can be used under harsh conditions; it has excellent work hardening (non-magnetic), and has good strength, plasticity, toughness and cold formability And good low temperature performance. Due to the addition of 2% Mo on the basis of Cr18Ni8, the steel has good resistance to reducing media and pitting corrosion. It has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts, and seawater. Its corrosion resistance in reducing acidic medium is much better than 304 and 304L.
