Cosmetic mechanical vacuum homogeneous emulsifying pot body material 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 chemical, chemical fiber, fertilizer and other industries. In addition to the atmospheric corrosion resistance and high temperature strength, can be used in the harsh conditions of the characteristics of the use of its intergranular corrosion resistance, excellent work hardening, seawater equipment, paper and other production equipment, acetic acid equipment.

Cosmetic mechanical vacuum homogeneous emulsifying pot body material 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 chemical industry, chemical fiber, fertilizer and other industries. In addition to the atmospheric corrosion resistance and high temperature strength, can be used in the harsh conditions of the characteristics of the use of its intergranular corrosion resistance, excellent work hardening, seawater equipment, paper and other production equipment, acetic acid equipment. It has good resistance to intergranular corrosion.
The maximum carbon content of 316L stainless steel is 0.03, which can be used for annealing and maximum corrosion resistance after welding. The corrosion resistance of SUS316L stainless steel is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulping and papermaking. And 316 stainless steel is also resistant to marine and aggressive industrial atmosphere.
In intermittent use below 1600 degrees and in 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 the 316 stainless steel, but when the 316 stainless steel is continuously used outside the temperature range, the stainless steel has good heat resistance. 316L stainless steel carbide precipitation resistance is better than the performance of 316 stainless steel, available in the above temperature range. Annealing is carried out in the temperature range of 1850-2050 degrees, followed by rapid annealing, and then rapid cooling. It has high temperature resistance, easy processing, high strength. 316L stainless steel, no need for post-weld annealing.
316L stainless steel added Mo, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used in the harsh conditions; excellent processing hardening (non-magnetic), with 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 is given good resistance to reducing media and pitting corrosion. In a variety of organic acids, inorganic acids, alkalis, salts, seawater are suitable for corrosion resistance. Its corrosion resistance is much better than that of 304 and 304L in reducing acid medium.
