Aço inoxidável vs aço galvanizado

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 […]

Evolução da microestrutura do aço P92 em diferentes temperaturas isotérmicas

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: Conheça os códigos de projeto de tubulação

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.
