Product Description

Specification:

Standard	DIN2391, DIN2445, EN10305, GB/T 3639, GB 8713
Grade	ST35(E235), ST37, ST24(E255), ST52(E355), 10#, 20#, 35#, 45#
O.D.	30MM-400MM
W.T.	2MM-30MM
Surface Treatment	bare, varnished, oiled, anti-corrosion coating as request
Packing	1. bundle packing 2. marking as per customer's requests 3. paint on the pipe as per customer request 4. pipe caps as customer request
Condition of Delivery	1. NBK(+N) after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium 2. GBK(+A) after cold forming, annealing in non oxidizing medium protective gas 3. BK(+C) the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee 4. BKW(+LC) after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring) 5. BKS(+SR) have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
