TORICH is a professional manufacturer of EN10305-1 precision seamless cold drawn steel tube. There are many delivery conditions like +N,+A,+C,+SR, which will lead to the different mechanial properties.

Size: Outer Diameter: 6-1000 mm,Wall Thickness: 1- 80 mm,Length :1-12m or as your request

Application:Hydraulic system

Material:10#.20#.16Mn.A106(B,C).ST35-ST52

Manufacture :Tubes shall be made by the seamless process and shall be cold drawn.

Surface: Galvanized, Black phosphating，etc.

Heat Treatment:

1)Cold-drawn tubes shall be heat treated after the finalcold-draw pass at a temperature of 1 200F [640C] or higher toensure ductility satis factory for rolling into tube sheets and tomeet mechanical properties as specified.

2)If stress -relief anneal of the U-bends is specified, theanneal shall consist of heating the bent portion within a rangeof 1100 to 1200F [585 to 640C].
