S700MC high-strength cold-formed hot-rolled steel sheet SPA-C corrosion resistant railway steel more greatly improves the yield strength than traditional steel grades, and at the same time has good elongation performance, cold bending performance, welding performance and impact resistance. S700MC high-strength steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large-scale welding structural parts.

The preparation of SPA-C corrosion resistant railway steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for SPA-C corrosion resistant railway steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

In April 8th, 2018, our Philiphine customer purchased 1008 Tons API 5L Gr.B ERW pipes &Q345B seamless steel pipe for offshore oildfield resources drilling project. This is a regular demand almost every two month, and we has been cooperated more than three times, totally around 2100 tons API 5L Gr.B steel pipeline since 2015 year. We can supply the relative certificated for the API 5L Gr.B ERW pipes products like SGS report, B/L &Form M, and mill test certificate.
