Precision cold drawn tube product difference

1. The main feature of ordinary seamless steel pipes is that they have no welds and can withstand greater pressure. Products can be very rough cast or cold drawn.
2. The precision cold-drawn tube is mainly the inner hole, and the outer wall size has strict tolerance and roughness, and the precision is high.
As the test temperature decreases, the cold brittle alloy steel with body-centered cubic lattice will change from ductile fracture to brittle fracture. Many industrial cold-rolled precision bright steel pipes will become embrittled in the temperature range from room temperature to subzero, which is called cold embrittlement.
