Product category: Welded tubes made of stainless steel

"Finepipe" to realize high tensile strength and weight saving!

"Finepipe"
– this is cold drawn welded tube Nippon Kinzoku manufactures and guarantees its quality by our unique technologies. This finepipe is precision tube superior to seamless tube.

=Quality Assurance=
Guarantee welding zone of tube by Thermo Profile Scanner
Guarantee all such as welding condition and scratches etc by Tube Inner Inspection System developed by ourselves
 
=Available size=
OD: 0.3mm – 22φmm, Thickness: 0.1mm – 2.2mm
Condition: Straight tube, Tube in coil, Cut Tube
 
=High Tensile Austenitic Stainless Steel Tube=
We have developed the unique high tensile Austenitic Stainless Steel grade "304NF" optimized for Automotive industry by adjusting chemical composition on high-tensile Austeniticc Stainless Steel(SUS304N2/UNS S30452) basis, applying our know-how.
Since this material is Austenitic Stainless Steel grade based on 304 and its basic feature is the same as 304/304L, it is possible to easily realize high-tensile and weight saving by gauge down even though peripheral components and ASSY condition(Brazing, Turning etc.) are the same as the current use.
This new grade has below features.
- Low Carbon(Max0.3%)
- High Tensile(0.2% proof stress:400MPa)
- High Strength(700MPa)
- Better brazing performance(comparison with SUS304N2/UNS S30452)
 
It is possible to apply this grade to not only Automotive but also other industries which require high-strength.
