 20# steel

20# seamless steel pipe material for the 20# steel, the intensity is slightly higher than the 15#, rarely quenching, no temper brittleness. Cold deformation, high plasticity, generally for bending, rolling, bending and hammer arch and other processing, arc welding and contact welding welding performance is good, gas welding when the thickness is small, strict shape or shape complex parts prone to crack. 20# seamless steel pipe Cutting process Cold drawn or normalized state is better than the annealed state, generally used in the manufacture of small force and toughness of the workpiece.

20# seamless steel pipe material: high-quality carbon structural steel
Grade: 20#
Standard: GB8162-2008 \ GB / T8163-2008 \ GB3087-2008 \ GB9948-2006 \ GB5310-2008
Heat treatment specification: normalizing, 910 ℃, air cooling. Microstructure: ferrite + pearlite.

Delivery status: No heat treatment or heat treatment (annealing, normalizing or high temperature tempering) state delivery. Requirements of heat treatment delivery should be specified in the contract, not marked by the heat treatment delivery.
