-CR treated coupon is due to light refraction by the treatment layer.
What advantages are gainedby applying Silcosteel®-CR treatment to steel and stainless steel compo-
nents in contact with corrosive environments? Silcosteel®-CR treatment will ensure longer lifetimes for
these components.Maintenance schedules canbe prolonged. Reduced corrosionwillmean less con-
tamination inprocess streams in contact with corroding steel substrates. Finally, Silcosteel®-CR treated
componentswill greatly reduce system cost, relative to super alloy components (e.g.,Hastelloy®or
Inconel®).
These fittings aremanufactured by
Parker Hannifin. Swagelok
®
fittings also are
available—see our website.
