Material EN steel grade S235J2 material Chemistry

SPV355 steel is a kind of Japanese standard steel for medium temperature pressure vessels. The executive technical standard of SPV355 steel is JIS G3115. SPV355 steel is widely used in petroleum, chemical industry, power station, boiler and other industries. SPV355 steel is used to make reactor, EN steel grade S235J2 material heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.

Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel EN steel grade S235J2 material not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
