  • AbstractTable of ContentsIntroductionIn this research work, a reliability analysis was carried on three Nigerian timber specie namely:Mitragyna ciliata (Abura), Afromosia elata (Afromosia) and Confusa Grandiflora (Berlinia) after classifying the species to international strength classification system using EN 338 (2003) with the aid of statistical package Easyfit (2010) . This was done after establishing the physical and mechanical properties in the laboratory using ASTM D193 (2000) and EN408 (2003). Mitragyna ciliata was assigned to strength ClaX20CrMoV11-1, 1.4922, 20H11MNF - boiler steelX20CrMoV11-1, is a similar grade to X22CrMoV12-1, 1.4923 with a martensitic structure in the heat-treated state. Designed for pressure and high temperature applications up to 600 for devices used mainly in the power, oil and chemical industries. Steel is mainly supplied in the form of hot-rolled boiler pipes, fittings and sleeves.

    Evaluation of Dissimilar Joint Properties Between UNS

    Evaluation of Dissimilar Joint Properties Between UNS S32750 and API X65 process was used to join UNS S32750 SDSS to API X65 high strength low alloy (HSLA) steel. The properties of weldments were investigated by the impact test, potentiodunamic and cyclic polarization tests. The statistical analysis of signal fluctuation was used to High Strength Low Alloy Steel - IMOAHigh Strength Low Alloy (HSLA) Steel. HSLA steels were originally developed in the 1960s for large-diameter oil and gas pipelines. The line pipe used in these projects required higher strength and toughness than mild carbon steel, and good weldability provided by a low carbon equivalent. The oil & gas sector is still market where the most

    High power disk laser-metal active gas arc hybrid welding

    Oct 29, 2015 · In this study, welding with hybrid heat sources combined with a high power disk laser and a metal active gas (MAG) arc was carried out on 780 MPa high strength steel plates of 12 mm in thickness. The effects of respective welding conditions, such as laser power, root gap and welding speed on the penetration, geometry, and defects of weld beads, were investigated. Hydrogen Induced Cracking and Sulphide Stress Corrosion Background:Trial productions of API-X65, API-X70 steels have been undertaken at Rourkela steel plant (RSP) and Bokaro steel limited (BSL) in collaboration

    Measurements of magnetic materials - IOPscience

    thickness variations in API X65 steel using magnetic hysteresis loop and artificial neural networks how geometrical and physical properties can often combine to make the determination of the to the ordinary laws of statistical mechanics and we can write M(H) Mechanical Characteristics and Adherence of Corrosion formation. Properties such as layer adherence, fracture toughness and hardness can potentially play a significant role in the previously described scenarios. Consequently, the primary motivation of this research was to characterize corrosion product layers with well-known methodologies utilized in tribology science and wear evaluation.
