CATRA Testing.I previously wrote an article on what CATRA testing is and what it is revealing from a set of tests on 154CM Maximizing Edge Retention.The CATRA edge retention test uses the slicing of 5% silica-impregnated cardstock and therefore tests slicing edge retention.
The influence of composition,heat-treatments,and microstructure of quenched and tempered Cr-Mo steels on their behavior under sulfide stress corrosion cracking is studied.Starting from a lCr-0.2Mo steel,with a UTS of 1015 MPa,laboratory heats of lCr-0.8Mo,lCr-0.2Mo-V,lCr-0.2Mo-V-Ti,and lCr-0.8Mo-V-Ti steels are prepared and tempered to UTS of 900 to 1000 MPa.SSC tests are conductedStress Relief Cracking in Advanced Steel Material-cracking are described.General guidelines on best practice are developed so that welders can minimize the risk of reheat cracking in welded fabrications.Table:1 Comparison of reactor steel conventional Cr - Mo and V modified Cr - Mo Steel grade Conven tional 2.25Cr-1Mo 2.25C r-1Mo-0.25 V Conve ntional 3Cr -1Mo 3Cr-1 Mo-0.2 5V-Ti-B 3Cr-1M o-0 Steel with Cr.,Mo.,Cr-Mo.,Steel with Cr.,Mo.,Cr-Mo Steel with Cr.,Mo.,Cr-Mo.Means the alloy steel whose alloy content are some Cr,Mo,or Cr-Mo.Most of Steel with Cr.,Mo.,Cr-Mo.is belong to alloy structural tool steel or the steel for pressure vessels The Main grade of Steel with Cr.,Mo.,Cr-Mo.Are EN 10028-2:16 Mo 3,14 Cr Mo 45 DIN 17155:16 Mo 3,13 Cr Mo 44 AFNOR 36206:15 D 3,18 MD 4.05 15 MDV 4.05 15 CD 2.05 15 CD 4.05

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
For example,a 1060 steel is a plain-carbon steel containing 0.60 wt% C.An H suffix can be added to any designation to denote hardenability is a major requirement.The chemical requirements are loosened but hardness values defined for various distances on a Jominy test.Reduced-activation ferritic steels A comparison with Cr$z Reduced-activation ferritic steels are being developed to replace the Cr Mo steels presently being considered for fusion-reactor applications.To meet the reduced-activation criteria,the steels cannot contain Mo,Nb,Ni.Cu,and N.Tungsten is proposed as a substitute for molybdenum,and niobium is replaced by tantalum and an increased use of vanadium.An initial series of Cr-W steels have Previous123456NextRecommended Practices for Welding of ChromiumIn this document,the chromium-molybdenum steel al-loys are referred to as Cr-Mo steels.Cr-Mo steels are used extensively in the power,chem - ical,and petroleum industries.The properties of such piping and tubing materials and the applicable fabrica-tion and inspection requirements are addressed in a wide range of documents,including:
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
