This specification applies to the supply of bearings for support of bridge superstructures for aggressive installations. For normal installations, steel bearings, in accordance with MRTS81 . Bridge Bearings, shall be used.Just plain carbon steel What is it? - The FabricatorFor A36/SA36 material, the tensile and yield strength are moderate. The yield is approximately 36,000 PSI, and the tensile strength varies from 58,000 PSI to 80,000 PSI. Variations in tensile strength allow for the difference in carbon, manganese, and silicon content in different thickness. Also the production methodrolling, hot or cold, or extrudingcan affect tensile strength. Additional carbon and manganese produce a higher strength but lower ductility. For example, the minimum elongation in 2-inSee more on thefabricator used in bridge engineering sa36 bridge equivalent Strip surfacing weldingEstimated Reading Time: 5 mins
