In the production of metal ball ring fillers
The standard for stainless steel ball ring packing is HG/T21556.2-95, which has the advantages of high temperature resistance, good processing performance, light weight, good toughness, high mass transfer efficiency, and good compressive strength. However, its corrosion resistance is different from that of plastic and ceramic packing. Therefore, the specific selection needs to be screened based on the above conditions. According to incomplete statistics of "100 second special steel", the materials for metal ball ring fillers include carbon steel, ordinary stainless steel, duplex steel, urea steel, 20 alloy, corrosion-resistant Monel 400, Hastelloy C276, 825 alloy, etc.
