These alloycompositions are normally considered for construction involv-ing plate thicknesses of 2 in. 50 mm or greater.1.2 Material under this specification is avail
4、able in twotypes, B and C. The material is also available in three classesas follows:Class Minimum Tensile Strength, ksi MPa1 105 7252 115 7953 90 6201.3 The maximum thickness of plates is limited only by thecapacity of the chemical composition to meet the specifiedmechanical property requirements.1
5、.4 The minimum plate thickness is316 in. 5 mm.1.5 These alloy steel plates in the as-rolled condition aresensitive to cracking during flame cutting, transit, and han-dling. They should be shipped in the as-rolled condition onlywith the mutual agreement of the manufacturer and thepurchaser or fabrica
