Ground & polished. +/ PART 2 MATERIALS 2.1 Range of Structural Steel Grades The grade designation (e.g. C250) is based on the nominal minimum yield strength of the steel (in MPa). The prefix C is used before the value of the nominal yield strength of the steel to indicate that the section is cold-formed. It should be noted that AS 1163 only considers cold-formed struc-tural steel Q345 steel property and specification are equivalent to Yield strength of Q345B is 345 Mega Pascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length. Tensile strength; The tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example breaking.
