Acier inoxydable ou acier galvanisé

Introduction Stainless Steel vs Galvanized Steel, it’s crucial to consider the environment, required durability, and maintenance needs. Stainless steel offers unmatched corrosion resistance, strength, and visual appeal, making it suitable for demanding applications in harsh environments. Galvanized steel, on the other hand, offers cost-effective corrosion protection for less aggressive settings. 1. Composition and Manufacturing Process […]

Evolution de la microstructure de l'acier P92 à différentes températures isothermes

Microstructure Evolution of P92 Steel at Different Isothermal Temperatures P92 steel is mainly used in ultra-supercritical boilers, ultra-high-pressure pipelines, and other high-temperature and high-pressure equipment.P92 steel is in the P91 steel chemical composition based on the addition of trace elements of W and B elements, reduces the content of Mo, through the grain boundaries of […]

ASME B31.1 vs. ASME B31.3 : connaître les codes de conception de tuyauterie

Introduction In piping design and engineering, selecting the appropriate piping code is essential for ensuring safety, efficiency, and compliance with industry standards. Two of the most widely recognized piping design codes are ASME B31.1 and ASME B31.3. While they both come from the American Society of Mechanical Engineers (ASME) and govern the design and construction […]

ASME BPVC Section II Partie A : Spécifications des matériaux ferreux

Introduction La section II partie A de l'ASME BPVC : Spécifications des matériaux ferreux est une section du code des chaudières et des récipients sous pression de l'ASME (BPVC) qui couvre les spécifications des matériaux ferreux (principalement le fer) utilisés dans la construction de chaudières, de récipients sous pression et d'autres équipements sous pression. Cette section aborde spécifiquement les exigences relatives aux matériaux en acier et en fer, y compris le carbone […]

Analyse des causes des fissures annulaires dans les tubes en acier sans soudure trempés SAE 4140

The reason for the ring-shaped crack at the pipe end of the SAE 4140 seamless steel pipe was studied by chemical composition exam, hardness test, metallographic observation, scanning electron microscope, and energy spectrum analysis. The results show that the ring-shaped crack of SAE 4140 seamless steel pipe is a quenching crack, generally occurring at the […]

ASME SA213 T91 : que savez-vous ?

Background & Introduction ASME SA213 T91, the steel number in the ASME SA213/SA213M standard, belongs to the improved 9Cr-1Mo steel, which was developed from the 1970s to the 1980s by the U.S. Rubber Ridge National Laboratory and the Metallurgical Materials Laboratory of the U.S. Combustion Engineering Corporation in cooperation. Developed based on the earlier 9Cr-1Mo […]
