S460Q steel plate is a quenched and tempered high-strength steel plate, the series grades are S460Q, S460QL, S460QL1, and the European standard EN10025-6 is implemented. S460QL1 steel plate is mainly used to manufacture low-temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc. It is a high-strength structural steel plate. S460QL1 steel plate delivery status: quenched and tempered (quenched + tempered).

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 16mo3 steel en standard 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.

Try to use 16mo3 steel en standard high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the 16mo3 steel en standard temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

S500MC steel plate/sheet,EN10149 S500MC steel plate/sheet, under EN standard, we can regard S500MC steel plate/sheet as high yield strength steels for cold-forming steels. 16mo3 steel en standard, EN10149 S500MC is mainly used as high yield strength steels for cold-forming steels. The EN10149 S500MC steel is equivalent to SEW092 QStE500TM, NFA E490D, UNI FeE490TM and ASTM X70XLK steel grades.
