506.2.3.1 Update references to current ASTM and AASHTO steel specifications (1) If using carbon steel castings for bridges and general use, conform to ASTM A781 class 70, AASHTO M103 class 70 or grade 70-36, or AASHTO M163 grade CA 15 and the following:1. Furnish the specific class of steel castings the plans show or are specified in the contract.
AASHTO M 270M/M 270 - Standard Specification for Grade 345W [50W], 345CR [50CR], or HPS 345W [HPS 50W] shall not be substituted for Grade 250 , 345 , or 345S [50S] without agreement between the purchaser and supplier. When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
ASTM A242. ASTM A242 is a high strength low-alloy structural steel specification with improved atmospheric corrosion resistance. This specification is normally applicable to steel plates through one-half inch in thickness. The atmospheric corrosion resistance of A242 is substantially better than that of carbon steels such as A36 and A572-50 with or without copper addition.
Comparing Steel Plate Gradesmachining. Medium carbon steel plates (.40 - .50) that are silicon killed offers better strength capabilities but have limited machining and welding properties. Other types of steel plate offer benefits for structure and construction applications, resistance to abrasion, and the ability to

Welding metals of dissimilar strengths - The FabricatorIn this situation, the chrome-moly may have a yield strength around 60 KSI and a tensile strength of 80 KSI; the A36 steel has a 36-KSI yield strength. Not only do you need to select a filler metal that matches the lower-strength material, but you also may need to find a filler metal capable of being stress-relieved.Just plain carbon steel What is it?
StrengthWear and Corrosion ResistanceDuctility and FormabilityFor 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-inch plate is 2A36 CARBON In Stock Castle Metals SiteCarbon A36 in Plate SPECIFICATIONS:ASTM A 36/ A6 /A709 ASME SA36 / SA6 Castle Metals stocks A36 plate throughout our global distribution and processing network.
