Precipitation-hardened steels, hydrogen embrittlement

Hydrogen embrittlement Occurs most often in high-strength steels, primarily quenched-and-tempered and precipitation-hardened steels, with tensile strengths greater than about 1034 MPa (150 ksi). Hydrogen sulfide is the chief embrittling environment. [Pg.30]

The martensitic and precipitation-hardening stainless steels are more susceptible to hydrogen embrittlement than are the austenitic alloys. The susceptibility of these stainless steels is sensitive to microstructure and strength level. Figure 22 shows the resistance to cracking for a martensitic (type 410) stainless steel and some precipitation-hardening stainless steels in an H2S-saturated solution [174]. The low resistance of type 410 stainless steel is typical for most... [Pg.146]
