How will Restek surface treatments work in my acidic environment?
Silcosteel®, Sulfinert®, and Siltek® treated materials have improved corrosion resistance,
but Silcosteel®-CR surface treatment is optimized to enhance resistance to hydrochloric, nitric,
and sulfuric acids. It provides a 10-fold improvement in corrosion resistance, compared to untreated
stainless steel, and a 4-fold improvement compared to Silcosteel®-coated stainless steel.
