ASME SA709 Grade 36 steel

ASTM SA709 “Standard Specification for Structural Steel for Bridges”  is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.02 on Structural Steel for Bridges, Buildings, Rolling Stock and Ships. There are eight grade in the standard ASTM SA709--Grade 36, Grade 50, Grade 50S, Grade 50W, Grade HPS 50W, Grade HPS 70W and Grade HPS 100W etc. Katalor always keeps thousands of steels structures for bridge usage including A709 materials.

SA709 Grade 36 is also included in Specifications A36/A36M, A572/A572M, A992/A992M, A588/A588M, and A1010/A1010M (UNS S41003), respectively. When the requirements of Table 10 or Table 11 or the supplementary requirements of this specification are specified, they exceed the requirements of Specifications A36/A36M, A572/A572M, A992/A992M, A588/A588M, and A1010/A1010M (UNS S41003). SA709 Grade 36 product availability is shown in Table 1.

Elongation and reduction of area not required to be determined for floor plates SA709 Grade 36. If A709 Gr.36 plates are wider than 24 in. [600 mm], the reduction of area requirement, where applicable, is reduced by five percentage points. If  A709 Gr. 36 plates are wider than 24 in. [600 mm], the elongation requirement is reduced by two percentage points. The adjusted elongation requirement of material SA709 Grade 36 is shown in the Tension Tests section of Specification A6/A6M.
