Product Description

SAE1020 High Precision Cold Rolled Steel Tube Cold Drawn Steel Round TubeQingdao Ironsteel International Trading Co., Ltd provide high quality, low priced Cold Rolled/Cold Drawn Seamless steel tube.  Our factory founded in 2002, 15 advanced production lines can make full range sizes of cold rolled seamless steel pipes(by carbon steel/alloy steel materials) . We haveour own testing labs, equipped with all necessary testing equipments for chemical analysis, water pressure testing, X-ray inspection, ultrasonic testing, eddy current inspection, tension testing, chemical testing, and so on. 
High precision cold drawn seamless steel tube identifies the precision steel pipe with high dimension precision (inside diameter and outside diameter). Good surface finish, excellent roundness and straightness, and uniform wall occurrence. It can be very popular in mechanical structure and hydraulic gym equipment. This cold rolled or cold drawn seamless steel tube can greatly lessen machining time,  raise the product excellence.

Introduction of delivery state
Designation Symbol Description
Cold finished (hard) BK Tubes do not undergo heat treatment following the final cold forming and,thus, have a rather high resistance to deformation
Cold finished (soft) BKW The final heat treatment is followed by cold drawing involving limited deformation.Appropriate further processing allows a certain degree of cold forming(e.g. bending expanding).
Cold finished and stress-relleved BKS Heat treatment is applled following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree
Annealed GBK The last cold forming process is followed by annealing in a controlled atmosphere
Normalized NBK The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere
Different kinds of delivery condition, surface of pipe can be bright, galvanized, phosphating, etc.
