20# steelpipe Implementation of standards
GB / T 699-1988
Features and Scope
Strength steel is slightly higher than the 15th, little quenching, temper brittleness. Cold plastic deformation is high, generally for bending, rolling, curved edges and hammer arch processing, and exposure to welding arc welding performance is good, when welding thin, form-critical or complex shape of the workpiece on the crack-prone. Machinability drawn annealed or normalized state than the state is good, generally used in the manufacture discontinuity large and require high toughness.
No heat: ≤ 156HB, sample size: Sample size 25mm
Heat treatment and microstructure specifications
Heat treatment specifications: normalizing, 910 ℃, air cooling. Microstructure: ferrite and pearlite.
Delivery status
To no heat or heat treatment (annealing, normalizing or tempering) state delivery. Requires heat treatment delivery should be specified in the contract, is not indicated by the heat treatment delivery.
