Stainless steel round bar

Round stainless steel bars have the widest range of grades and sizes available. They are used in many fields, in particular automobiles, ships, aircraft, various types of precision components, industrial machines, household information equipment, and construction and civil engineering. Furthermore, because of their high durability lately their uses have been increasingly expanding to semiconductors, nuclear power and chemical plants. Small and large volume production, quick delivery, and "forward arrangements" are also available.

Peeling (PM) - Stainless steel round bar -

Mill scales on the surface have been cut after hot rolling. The surface has a glossy finish.
This bar is traded at high volume, and has extensive general uses.
Generally produced with a positive tolerance (-0).

Drawing (CD, finished) - Stainless steel round bar -

CD stands for "cold drawing." The material has been drawn through a steel die without being heated. The surface has a glossy finish. Achieves better dimensional accuracy than with peeling or pickling.
Generally of Class h9 tolerance.

Grade Size
SUS304 φ5~φ90
SUS303 φ6~φ55
SUS316 φ6~φ70

Grinding (CG) round bar - Stainless steel round bar -

CG stands for "center-less grinding." This method grinds the material by passing it between two rotating grinding stones. These bars are used when better size, surface roughness, and roundness accuracy is required than found with general drawn products. They cost more than drawn products.
Generally of Class h7 tolerance.

Grade Size
SUS304 φ3~φ60
SUS303 φ3~φ60
* Our customers include a number of leading Japanese manufacturers. Please contact us for other grades or sizes.
