Product Description

EN10216-2 25CrMo4 10CrMo9-10 Seamless Steel Tubes for Pressure Purposes


TORICH with more than 20 years experience in manufacturing and exporter is a supplier of steel tube,  We have exported over 60 countries like Korea, German, France, Malaysia,etc. Our aim is to bring our steel tube to the over world.


Dimension of EN10216-2 Seamless steel tube:

+N= Normalisingh,including Normalising Forming

+NT= Normalising + Tempering,

+QT= Quenching+ Tempering( air or liquid)

+l= Isothermal Annealing


Size range of EN10216-2 steel tube:

OD: 5-420mm


Length: according to request   


Tolerance on OD and WT:

OD Tolerance on D Tolerance on T for a T/D ratio
D≤219.1 mm ± 1% or ±0.5mm whichever is the greater ≤0.025 >0.025, ≤0.05 >0.050, ≤0.1 >0.1
D>219.1 mm ±12.5% or ±0.4mm whichever is the greater
±20 % ±15% ±12.5% ±10%


Appearance Condition:

The tube shall be free from external and intenal surface defects that can be detected by visual examination.


The external and intenal surface finish of the tubes shall be typical of the manufacturing process and where applicable, the heat treatment employed. Normally the finsh and surface condition shall be such that any surface imperfections requiring dressing can be identified.


It shall be permissible to dress, only by grinding or machining, surface imperfection provided that after doing so, the wll thickness in the dressed area is not less than the specified minimum wall thickness. All dressed areas shall blend smoothly into the contour of the tube.


Surface inperfections which encroach on the specified minimum wall thickenss shall be considerated defects abd tubes containing these shall be deemed not to conform to this part of EN 10216.


Any surfac imperfection, which is demonstrated to be deeper than 5% of  the wall thickness T or 3mm whichever is the smaller, shall be dressed.

*Good abilities of stress corrosion, all kinds of localized corrosion,antioxidant corrosion(including high temperature oxidation resistance).

*Low density

*Good thermal conductivity: It is 30%-50% higher than Austenite. Small coefficient of thermal expansion: It is 30%-40% less than Austenite.

*Big elastic modulus

*Good processing properties

*Easily bending, stamping, curling, pinin, cold forging and machining.

*Excellent deep drawability


1~ Incoming Raw Material Inspection
2~ Raw Material Segregation to avoid steel grade mix-up
3~ Heating and Hammering End for Cold Drawing
4~ Cold Drawing and Cold Rolling, on line inspection
5~ Heat Treatment, +A, +SRA, +LC, +N, Q+T
6~ Straightening-Cutting to specified length-Finished Measuring Inspection
7~ Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8~ Packing and Stocking.

100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
