Precision Seamless Steel Tubes Delivery Condition BKS Standard EN10305-1 Steel Round Pipe
Description Precision seamless steel tube is a high precision steel tube after cold rolling or cold drawing
Main Date
BKS(+SR): After the final cold drawing process there is a stress relieve heat treatment in a controlled atmosphere.
Other Delivery Conditions NBK(+N): After the final cold drawing operation the tubes are normalized in a controlled atmosphere. GBK(+A): After the final cold drawing process the tubes are annealed in a controlled atmosphere. BK(+C): No heat treatment after the final cold drawig process. BKW(+LC): After the final heat treatment there is a suitable drawing pass.
Advantage 1. Smaller outer diameters; 2. High precision can be done in small batch production; 3. Cold drawing finished products with high precision and good surface quality. 4. The transverse area of the steel tube is more complicated; 5. Steel pipe performance is superior, metal is more dense.
