Delivery Conditions

1. BK (+C)

No heat treatment after last cold forming process.

2. BKW (+LC)

After last heat treatment there is a light finishing pass (cold drawing)

3. BKS (+SR)

After the final cold forming process the tubes are stress relieve annealed.

4. GBK (+A)

After the final cold forming process the tubes are annealed in a controlled atmosphere.

5. NBK (+N)

After the final cold forming process the tubes are annealed above the upper transformation

point in a controlled atmosphere.

6.SR

Stress Relief process

7.Q+T

Quenching and tempering to HRC30-HRC45

Seamless Steel Pipe mills, volume should go through continuous annealing (CAPL unit) to eliminate cold hardening and rolling stress, or batch annealing reach the Automotive and mechanical tube and pipes Special alloy steel Thick Wall Seamless Steel Pipe and tube carbon steel tube mechanical properties of the corresponding standard specifies. Seamless Steel Pipe surface quality, appearance, dimensional accuracy Automotive and mechanical tube and pipes Special alloy steel Thick Wall Seamless Steel Pipe and tube carbon steel tube better than hot-rolled plate, and right-rolled thin product thickness is about 0.18mm, so the majority of users favor.
