Slow strain rate tensile and fatigue properties of CrMo

CrMo steel JIS-SCM435 and carbon steel JIS-SM490B were investigated. SSRT and fatigue tests were conducted in 115 MPa hydrogen gas. In both the steels,a ductility loss was observed in hydrogen gas. No hydrogen-induced degradation was observed in fatigue strength in long-life regime.Selection guidelines for corrosion - Stainless Steel World13 Cr (Martensitic Stainless Steel) Figure 1 represents the generally acceptable regions of performance for 13 Cr stainless steel exposed to wet CO 2 containing NaCl.This figure is only applicable in the absence of oxygen and hydrogen sulphide (H 2S).Small amounts of oxygen can cause severe pitting of 13 Cr in the presence of chlorides.STEEL PREHEATING CHART - Crown AlloysMetal Metal %C Recommended Group Designation Preheat (0F) Plain Plain carbon steel Below.20 Up to 200 Carbon Plain carbon steel .20-.30 200-300 Steel Plain carbon steel .30-.45 300-500 Steel 8% Cr.- 1% Mo.steel .15 max 600-900 High Chrome 12-14% Cr.type 410 .10 300-500 Steels 16-18% Cr.type 430 .10 300-500

Postweld Heat Treatment Code Exemption - Pt 1 - TWI

For C-Mn and Cr-Mo steels,the lower thickness threshold embodied in ASME B31.1 and B31.3 ,compared with the other standards,may reflect the likelihood that the welding will be carried out in the field,and that defect rates and defect sizes may be greater than for shop welds.Microstructure,Deformation and Fracture Behavior of Cr-Mo Feb 02,2013 what tests are recommended on 13 cr mo steels#0183;The paper reports the uniaxial deformation and fracture behavior of two Cr-Mo-V steels used for nuclear structural components.The two steels are a new member of low alloy steel in the 3Cr-1Mo class and a plain tempered martensitic stainless steel containing 12% Cr.The microstructure investigations were carried out on the 3Cr-1Mo steel by establishing the continuous coolingMATERIAL GRADES - MeusburgerCr 0.40 0.40 0.30 13.00 720 N/mm what tests are recommended on 13 cr mo steels#178; Steel for through hardening low corrosion,high-alloy Cavity plates and inserts for the processing of plastics,mainly for the processing of corrosive plastics 1.2083ESU (ESR) DIN AFNOR AISI X 40 Cr 14 Z 40 C 14 420 ESR C Si Mn Cr 0.40 0.40 0.30 13.00 720 N/mm what tests are recommended on 13 cr mo steels#178; Steel for through hardening
