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.
ASTM Weathering Steel Specifications Central Steel ServiceASTM 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.
conform to the requirements of astm a709 grade 36. certified fy = 50 ksi. anchor plates, and splice tube plates shall conform to the requirements of astm a500 grade b or c with a of astm a709 grade 50. hollow railing structural tubing shall rail post and base plates shall conform to the requirements all items shown.
ITEM 711 STRUCTURAL STEEL AND STRUCTURE 711.04 Cold Rolled Steel. Provide cold rolled steel in accordance with ASTM A 108, Grades 1016 through 1030 for pins, rollers, trunnions, and other similar parts. 711.07 Steel Castings. Provide steel castings in accordance with ASTM A 27/A 27M, Grade 65-35 or Grade 70-36
Milling inserts and grades for hardened steelBecause of its exceptional resistance to plastic deformation, thermal cracking and other types of wear, this grade can withstand long periods of time in cut and is suitable for machining hardened steel from 36

ASTM A709 steel consists of A709 grade 36, A709 grade 50 and A709 grade 50W, etc. ASTM A709 steel grades are often specified with Charpy tests referring the specific zone or lowest anticipated service temperature. ASTM A572 steel plate is high strength low alloy steel recommended for riveted, bolted, or welded structures.
