Railroad Spike and Road Spike Is Only One Word Changed

A railroad spike is used on rail track to fix the rails, which is completely made of iron or steel. It is thought as a kind of key rail accessories for safety of railway transportation. Common raw materials of steel include:Q235, 45#, 40Cr, 35CrMoA, Q345B, Q345D and 20MnTiB in China. B. Classification and function of railway spikes Steel Portal Frame Buildings - China Building Material Steel provides several advantages over other building materials, such as wood:Steel is structurally sound and manufactured to strict specifications and tolerances. Any excess material is 100% recyclable. Steel does not easily warp, buckle, twist or bend, and is therefore easy to modify and offers design flexibility. Steel is also easy to install. What materials are used for high strength bolts_BeiJing Oct 12, 2019 · The 40Cr high-strength bolt is mainly used in the bolt ball node network frame, and its design strength is generally 390MPa (d>=30mm) or 430MPa (d <30mm), without high pre-tensile stress in use.Attention should be paid to understanding and ensuring the delayed fracture performance when applying high pretension.The delayed fracture performance of 20MnTiB high strength bolt is better
