20# seamless steel pipe cutting

The 20# seamless steel pipe is made of 20# steel. Its strength is slightly higher than that of 15#. It is rarely quenched and has no temper brittleness. Cold deformation has high plasticity, generally used for bending, rolling, flange and hammer arching, etc., arc welding and contact welding have good welding performance, small thickness during gas welding, and cracks are likely to occur on parts with strict requirements or complex shapes.
 
20# Seamless steel pipe cutting
The machinability cold drawn or normalized state is better than the annealed state, and is generally used to manufacture workpieces with low stress and high toughness requirements.
 
20# seamless pipe heat treatment specification and metallographic structure:
Heat treatment specification: normalizing, 910℃, air cooling. Metallographic structure: ferrite + pearlite.
20# seamless steel pipe delivery status: delivery without heat treatment or heat treatment (annealing, normalizing or high temperature tempering). If the delivery is required to be delivered under heat treatment, it should be indicated in the contract. If it is not specified, the delivery shall be delivered without heat treatment.
