We have a wide selection of steel standards with carbon and sulfur certification. Carbon ranges from 0.0057% to 2.410%, and sulfur ranges from 0.0004% (4 ppm) to 0.387%. These standards are available in various forms: 1 and 0.5 g pin and 1 g rings. We can offer them as a powder or chips as well. All CRMs have been certified according to ISO 17034 and ISO/IEC 17025.

In addition to steel standards, we can also offer titanium (Ti) and zirconium (Zr) standards with certified carbon and hydrogen content and cast iron standards with carbon and sulfur certification.
We also offer steel standards in which oxygen, nitrogen or hydrogen have been certified. The mentioned standards are most often in the O/N configuration as 0.5 or 1 g pins. C/S/N steel CRMs are also available as chips.
