Deformed rolling can improve strength and reduce weight. For example, performance is improved by deforming the properties and cross section of the metal, such as improving wear resistance using work hardening and reducing weight by thinning.
High Strength
Work hardening that occurs when processing metal materials is controlled by rearranging the deformed rolling process. Abrasion resistance and strength are improved.
Product & Plant IntroductionDeformed steel realizes productivity and cost reduction. For example, parts that have been machined with irregularities are replaced with deformed steel. It improves productivity and cost by eliminating laborious processes such as rolling the parts to be polished to close to the product dimensions by irregular rolling and reducing cutting chips.
Switching from cutting and polishing
Productivity can be improved by changing the material to deformed steel. For
example, by substituting deformed steel for parts that were cut after pressing or parts that had been made uneven by cutting, productivity and cost can be improved by omitting cutting.
Improves continuous processing and yield by changing the form of the material from the standard size to the coil
Costs can be improved by changing the form of the material. For example, by
changing the form from a standard size product to a coil winding and making it continuous processing, the setup and loss that occurred for each one can be reduced, and the yield and productivity can be improved.
Improved workability and simplification of parts
Work efficiency can be improved by thinning the hole drilling area, and increasing the wall thickness of the insufficiently thick part leads to higher strength and simplification of parts.
Fine pipes have the highest level of pressure resistance and can be made lighter and stronger. For example, the pressure resistance performance can be improved with the same dimensions, or the pipe performance can be improved by reducing the weight by reducing the wall thickness while maintaining the pressure resistance performance.
Pressure resistance and durability that surpass seamless
Fine pipe has pressure resistance and durability that surpasses seamless pipes due to its very small thickness uneveness and unique welding technology improvised by our own R&D department.
Good plate thickness accuracy (very small thickeness uneveness)
Since the high-precision coil material are roll formed and welded* into a tubular shape by forming, the plate thickness accuracy is high = it has excellent uneven thickness around the tube. (nearly to same thickness surround the wall
Welded part has the same quality as the base material
By properly combining the pipe making process (cold working and annealing), resulting the quality of the welded part is infinitely equivalent to that of the base metal part.
As for the mechinary properties; strength & workability are same without any difference on the welded section & base material.
Welded full length guarantee
The full length welded is guaranteed by measuring the temperature distribution of the welded part and conduct leak test by using second smallest atom (Helium).
Ability on detecting even very small defects.
Fine Pipe process _ Nippon Kinzoku (Gifu Plant)A steel grade with improved strength and proof stress within the JIS component range of SUS304, it is the most suitable material for parts in high-pressure environments and environmental applications where improving strength without changing dimensions.
