For GB/T 699 20# carbon steel, GB/T 699 20# round bar is mainly applied to machinery parts which requires high toughness and bears small stress,such as lever,axle sleeve,straining beam. GB/T 699 20# round bar can also be used in the line of agricultural machinery or cars, to produce carburization or carbonitriding parts,such as lever shaft,plunger. GB standards,GB/T,Guobiao Standard,CNS standards of GB standards are the China national standards, also called as Guobiao Standards, China GB standards are classified as two stages, Mandatory or Recommended. Mandatory standards have the force of law as do other technical regulations in China. They are enforced by laws and administrative regulations and concern the protection of human health GB/T 12467.4-2009, PDF in English.---GB/T 12467.4-1998.

The biggest impact of the new GB/T 1591-2018 release is Q345B, because the output of other grades has little effect. According to what we said Q235 Steel Equivalent, Properties, Specification, CompositionQ235 Steel (Q235A Q235B Q235C Q235D) Q235 steel is a plain carbon structural steel which is widely used in China, Q235 material in Chinese standard GB/T 700 is divided into 4 quality grades:Q235A, Q235B, Q235C and Q235D; Density of this steel is 7.85 g/cm3, tensile strength is 370-500 MPa; yield strength is 235 MPa (data are for steel bar or steel plate diameter 16mm).
