Pressure vessel plates, commonly referred to as boiler steels, are critical materials in industries that require robust and reliable components to operate under high pressure and temperature conditions. These pressure vessel steels can be broadly classified into two categories: alloyed and unalloyed. At Sidertaglio Lamiere srl, we specialize in non-alloy pressure vessel steel for boilers, compliant with major international standards such as EN10028, ASME, and ASTM.

The chemical composition and mechanical properties of boiler steels are meticulously crafted to meet the rigorous requirements set by global standards organizations. For example, a steel grade like P355NH is commonly certified according to EN10028, but it can also meet specifications for P355NL2 or conform to American standards as SA 516 GR 70 or ASTM A 516 GR 70.

These steels are characterized by their fine grain structure and are often quenched, which enhances their mechanical properties, making them ideal for use in high-pressure environments. The steels can be processed from both coil and quarto rolling, offering flexibility in manufacturing. Their excellent weldability and optimal mechanical characteristics make them suitable for constructing a variety of pressure vessels, such as boilers, heat exchangers, storage tanks, and penstocks.

In the petrochemical industry, these steels are widely used for manufacturing pipes and fittings due to their ability to withstand extreme conditions without compromising on safety or performance.

Boiler steels and pressure vessel plates typically come with a complete producer certification of 3.1, which provides detailed information on their chemical composition and mechanical properties. However, these materials often undergo further verification and testing by authorized bodies to ensure compliance with additional standards. For instance, certification 3.2 may be required, or supplementary tests such as those specified by PED (Pressure Equipment Directive) or AD2000 standards, which are critical in industries where safety is paramount.

At Sidertaglio Lamiere, we offer a comprehensive range of services tailored to your specific needs. Whether you require whole sheets, parts of sheets, or customized cuts based on detailed designs, we ensure high-quality, precision-engineered products. Our expertise in processing and supplying pressure vessel steels makes us a reliable partner in industries that demand nothing short of excellence.

Understanding the properties, certifications, and applications of pressure vessel plates and boiler steels is crucial for industries where safety, reliability, and performance are non-negotiable. At Sidertaglio Lamiere srl, we are committed to providing the highest quality materials that meet and exceed industry standards, ensuring your projects are built on a foundation of strength and durability.
