 20 Steel 
 Implementation of standards 
 GB / T-699-1988 
 Features and Scope 
 Intensity slightly higher than the 15 # steel, very little quenching, temper brittleness. Cold deformation of high plasticity, usually for bending, rolling, curved edges and hammer arch processing, arc welding and the welding performance of contact welding, gas welding, thin, shape requires strict or complex shape parts prone to cracks. The machinability drawn or normalizing state than the annealed condition is good, generally used for the manufacture of uneven force and high toughness requirements. 
 No heat: ≤ 156HB, the sample size: sample size of 25mm 
 Heat treatment and microstructure 
 Heat Treatment Specification: normalizing, 910 ° C, air-cooled. Microstructure: ferrite and pearlite. 
 Delivery status 
 No heat treatment or heat treatment (annealing, normalizing or high-temperature tempering) state delivery. Require heat treatment delivery should be specified in the contract, does not indicate no heat treatment delivery.
