we have sold 4140 hot rolled and 4130 cold drawn steel tube before,aslo we can produce machined steel pipe according to drawing,we have sold to Israel,brazil,Portugal and son on,u can check some of the pictures below
4130 steel tube
Delivery condition:
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
Production routing:
Quality carbon steel from bao steel etc big mill, cold drawing the heat treatment without oxidization , NBK condition. Do nondestructive testing ,HT tests and do dipping oil antirust protection, Packed tube in wooden boxes.
Main feature:
High precision
Excellent brightness
No oxidization on outer and inner walls after heat treatment
High cleanness of inside wall
High pressure
No deformation after clod bending
No crack after flaring and flattening
