Products for this application
AISI 304 / 316 / 316L
Compare 304 with 316 / 316L for chemical media and corrosion exposure; confirm compatibility with the fluid, temperature and cleaning process.
AISI 420 / 440C
Consider hardenable stainless grades when hardness and wear are specified.
Ceramic balls
Assess composition, compatibility and sealing contact for the intended fluid.
