"Finepipe" - These are cold drawn welded tubes manufactured and guaranteed by Nippon Kinzoku's unique quality control technologies. These Finepipe are precision tubes superior to seamless tubes.
1)Guarantee the quality of welded zone by Thermo Profile Scanner
2)Guarantee inner surface quality such as scratches by Tube Inner Inspection System developed by ourselves
1)OD: 0.3mm - 22mm, Thickness: 0.1mm - 2.2mm
2)Condition: Straight tube, Tube in coil, Cut Tube
We have developed the unique high tensile strength Austenitic Stainless Steel grade "304NF" optimized for the Automotive industry by adjusting chemical compositions on the basis of high-tensile Austenitic Stainless Steel(SUS304N2/UNS S30452), and by 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 down gauging without changing the following peripheral components and ASSY conditions(Brazing, Machining etc.)
This new grade has the following features.
- Low Carbon(Max0.3%)
- High Proof Strength(0.2% proof stress :400MPa)
- High Tensile 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.
