China 45 Steel. Chinese GB standard 45 steel is a quality carbon structural steel, the cold plasticity is common. Annealing and normalizing are slightly better than quenching and tempering, and have high strength and good machinability. A certain degree of toughness, plasticity and wear resistance can be obtained after appropriate heat treatment.
Chinese GB Standard - World MaterialQ345 Steel Properties Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa, it has better properties than Q235.
In the UK, the nominal values of the yield strength (f y) for structural steel, and hence the characteristic values used in design calculations, are obtained by adopting the minimum yield strength (R eH) values direct from these product standards.. S275 steel is often used on railway bridges, where stiffness rather than strength governs the design, or where fatigue is the critical design case.
PART 2 MATERIALS 2.1 Range of Structural Steel 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
