Lower Body Upper Body Scrubber Material Selection Suitable Material for each condition of U-Type Scrubber Upper Body Lower Body Inlet Duct Moisty Zone Corrosive Zone Severe Zone Duplex (S32750) Super Duplex (S31803) SMO254 (S31254) Lower part is very important due to its high sulfur contents Super Duplex for the lower body in order to ensure longer lifetime of the scrubber body Copyright c 2018 Hyundai Materials All right reserved. www.

All Parts (incl. Internal Components) Scrubber Material Selection Suitable Material for Continuous Dry Running (In-Line Scrubber) Section Condition Scrubber Body Needs to be run without Water Spray Material SMO254 (UNS S31254) Since the In-Line(I-Type) Scrubber has no bypass lines, it needs to be run without water spraying which is called dry running. The material has to endure high temperature and thermal stress, so we applied SMO254 at all parts. Copyright c 2018 Hyundai Materials All right reserved. www. Hyundaimaterials.com 22
