ASTM 36 is the most common alloy steel. It is used for most building components, including columns, beams, decorations, and completion elements. ASTM A36 NM400 use for bridge ductility does not allow the alloy to be used as a cable or as reinforcement (reinforcement). However, ASTM A36 is also perfect for most other purposes.

NM400 use for bridge, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe NM400 use for bridge for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
