| Product Description | ||||
|
SM17CRS-125 is a Martensitic - Ferritic stainless steel OCTG material referred to as "Super 17 Chrome". This material was developed for HPHT flow wetted applications where high strength is a prerequisite. SM17CRS-125 is suitable for sweet environments with small amounts of H2S, under which standard Carbon and low alloy steels would suffer localized corrosion also called mesa or ringworm corrosion. "Super 17 Chrome" bridges the gap of performance between Martensitic and Duplex materials while expanding the application domain with regards to temperature, H2S content and Chloride concentration.
