We can manufacture according to your desired hardness between annealed to full hardened as shown in the table below.(The hardness of hardened steel strip is to be discussed each by each)
Some finishes may not be available depending on the thickness of the sheet, so please consult with us first.
*For ultra-thin foil, soft materials such as annealed or BA finish may not be applicable due to concerns about defects (folding, wrinkling, etc.).
RB-S can be hardened by quenching and tempering.
The max quenched hardness is[620-680HV].
Please select tempering temperature according to required hardness and toughness by referencing quenching and tempering curve.
Material which is used to make various blades such as razor blades, shaver blades, and medical blades. Depending on the application and required properties, you can choose from a variety of options such as high carbon steel or martensitic stainless steel.
They have a high carbon content and can acquire extremely high strength if quenched after stamping.
We provide quenched stainless steel strips.
