Number steel stamps offer 0–9 digits in chrome-vanadium steel (CRV/6150), face-hardened to 58–62 HRC.
Available in standard, heavy-duty and reversed styles — for metal marking, sequential numbering and part traceability.
Character heights run from 1.0mm to 19.0mm; the standard YC602 line offers 14 sizes, with the square shank growing from 6.35mm (1.0–4.0mm characters) to 19.05mm (19.0mm characters). Number steel stamps are typically used for serial numbers, batch codes and part traceability; if the content changes often and you need a whole row in one strike, consider the YC610B interchangeable steel type kit. Young Cycle is a steel stamp manufacturer in Taiwan, producing in our own Taichung plant since 1986, with custom steel stamps made to drawing and OEM / ODM welcome.
