Questions about a grade, a correction to a value, a standard we should add, or a supply enquiry for the steels listed here — write or call. We answer in English and Turkish.

Corrections and additions

Every value on this site names the standard edition it was checked against. If you find a discrepancy, send the grade, the property, the value you expect and the standard's table number; verified corrections are published with the next data edition and the page's "last checked" date is updated.

Supply enquiries

The site is operated by Omega Steel Co. (Omega Çelik, Istanbul), a stockholder of structural, pressure-vessel, stainless and engineering steels with a warehouse in Dilovası. For availability, cutting and export enquiries on the grades listed here, use the Istanbul number or email; for UK and EU projects the London office.
