The influences of impurity content,tensile strength,and

The influences of impurity levels,grain size,and tensile strength on in-service temper embrittlement of CrMoV steels have been investigated.The samples for this study were taken from several steam turbine CrMoV rotors which had operated for 15 to 26 years.The effects of grain size and tensile strength on embrittlement susceptibility were separated by evaluating the embrittlement behavior The cooperative relation between temper embrittlementA sample plate of HY 130 steel (5 pet Ni-0.5 pet Cr-0.5 pet Mo-0.1 pet V-0.1 pet C) was found to be quite susceptible to temper embrittlement.Step-cooling produced a shift in transition temperature of 583 K (310 astm temper embrittlement#176;C).In the step-cooled condition the plane strain stress intensity threshold for crack growth in 0.1 N H2SO2 was about 22 MNm-3/2 (20 ksi in.) and the fracture mode was inter The Symposium on TemperEmbrittlementin Steel was held at ASTMHeadquarters in Philadelphia,Pa.,3-4 Oct.1967.The sponsor of this symposium was ASTMSpecial Task Force on Large Turbine and Gen- erator Rotors,Subcommittee VI of Committee A-l on Steel.TEMPER EMBRITTLEMENT - ASTM InternationalWas this helpful?People also askWhat is temper embrittlement?What is temper embrittlement?Temper embrittlement can occur at any time the alloy passes through the embrittlement temperature range for an extended period of time,e.g.during tempering and/or during slow cooling.Large pieces of alloy are more susceptible to TE due to the interior not being able to cool as quickly.Embrittlement - Fastenal
