Material Selection For Sanitary Fittings: Why The Medical Industry Must Use 316L Stainless Steel

In medical fluid systems, 316L stainless steel sanitary fittings are an irreplaceable choice. Its ultra-low carbon content (<=0.03%) completely prevents intergranular corrosion, while the addition of molybdenum increases the pitting resistance equivalent number (PREN) to 25+. Leadtek's GMP-certified production line offers sanitary fittings with a mirror-polished surface (Ra<0.5μm), far exceeding the 3-A sanitary standards.

Comparative tests show that the metal ion release of 316L stainless steel under wet heat sterilization conditions is only one-third that of 304 material. This is precisely why Leadtek's medical-grade ball valves are made entirely from 316L forged stainless steel.
