Delivery condition of 4130 Precision Seamless Steel Tube :
The tubes can be produced in the following delivery conditions:
BK (+C) Cold finished/hard (cold finished as drawn).
No heat treatment after the last cold forming process.
BKW (+LC) Cold finished/soft (lightly cold worked)
After the last heat treatment there is a light finishing pass (cold drawing).
BKS (+SR) Cold finished/stress relieve annealed.
After the final cold forming process the tubes are stress relieve annealed.
GBK (+A) Annealed.
After the final cold forming process the tubes are annealed in a controlled atmosphere.
NBK (+N) Normalized. (Mainly focus on)
After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere
Main uses of 4130 Alloy Steel Mechanical tubes: high precision steel pipe for hydraulic systems,
steel pipes for automobiles, and other customers who have high requirements for steel pipe accuracy,
smoothness, cleanliness, and mechanical properties.
