Abstract

Foreliggende oppfinnelse tilveiebringer et martensittisk rustfritt stål i hvilket spesifiserte elementer i en stålsammensetning er begrenset. Det martensittiske rustfrie stålet kan ha høy styrke av 0,2% konvensjonell flytegrense på 860 MPa eller mer og utmerket karbondioksidgass korrosjonsmotstand og sulfid spenningskorrosjonssprekkingsmotstand ved å begrense stålsammensetningen av spesifiserte elementer og definere Mo-innhold i stålet ved forhold med IM-verdier så vel som ved å danne mikrostruktur av stålet med hovedsakelig anløpt martensitt, karbid utfelt under anløping og intermetalliske forbindelser slik som Laves fase, en (-fase, og lignende. Som et resultat kan de martensittiske rustfrie stålene ifølge foreliggende oppfinnelse anvendes til praktiske stål, som kan anvendes vidt i oljebrønnrør og lignende under miljø som inkluderer karbondioksidgass, hydrogensulfid, klorioner eller to eller flere av dem, innen vide felter.The present invention provides a martensitic stainless steel in which specified elements of a steel composition are limited. The martensitic stainless steel can have a high strength of 0.2% conventional flow limit of 860 MPa or more and excellent carbon dioxide gas corrosion resistance and sulphide stress corrosion crack resistance by limiting the steel composition of specified elements and defining Mo content in the steel at ratios with IM values. by forming microstructure of the steel with mainly tarnished martensite, carbide precipitated during annealing and intermetallic compounds such as the Lave phase, a (phase), and so on. As a result, the martensitic stainless steels of the present invention can be used for practical steels wide in oil well pipes and the like under environment which includes carbon dioxide gas, hydrogen sulfide, chlorine ions or two or more of them, in wide fields.
