Sandvik 14C28N vs Alleima: Naming, Datasheets and Steel Identity
Understand the Sandvik-to-Alleima name change and verify 14C28N steel identity without relying on listing language.
Short answer
“Sandvik 14C28N” remains common search and catalog language, while current official product pages and datasheets are published under Alleima. The steel question is therefore not Sandvik versus Alleima performance; it is whether the quoted material is traceable to the requested 14C28N specification.
- Sandvik wording may be legacy naming rather than a different steel.
- Use the current Alleima page and datasheet for official grade facts.
- Brand wording on a listing is not proof of blade material.
- Keep grade, batch documents and finished-sample results as separate evidence.
Published facts and what they mean
| Decision layer | What the buyer should record |
|---|---|
| Legacy search name | Sandvik 14C28N. |
| Current official publisher | Alleima. |
| Required buyer evidence | Written grade specification, traceable material documentation and a tested finished sample. |
A material datasheet describes controlled steel from its producer. It should be treated as the starting specification, while the finished knife is approved through its own drawing, heat-treatment record and test results.
How to use the facts in a knife decision
Why both names appear
Corporate and product naming changes move faster than marketplace copy, packaging templates and buyer habits. Old wording can be understandable, but it should trigger clarification rather than an automatic rejection or acceptance.
What a credible document chain looks like
The RFQ names the grade; the supplier quotation repeats it; the approved drawing and purchase order lock it; material records support the batch; finished QC confirms hardness and product requirements.
What wording cannot prove
A product title, blade laser mark or sales message can be copied. None of them independently confirms chemistry, heat treatment or the identity of the production batch.
Worked buyer scenario
Decision example
If one quotation says “Sandvik 14C28N” and another says “Alleima 14C28N,” do not assume different performance. Ask both suppliers to map their wording to the current grade datasheet and provide the same sample evidence. Compare the resulting knives, not the age of the label.
Verification and sample plan
- Put the current grade name and acceptable legacy wording in the RFQ.
- Request the exact document that supports the quoted material source.
- Match the sample ID to the quotation, drawing and test record.
- Repeat the identity requirement on the production purchase order.
- Treat unexplained substitutions as a change requiring written approval.
The acceptance plan should say who tests, which samples are selected, what counts as pass/monitor/reject and what happens when one result falls outside the approved boundary.
Frequently asked questions
Did Alleima replace Sandvik 14C28N?
Alleima is the current publisher of the official 14C28N knife-steel information. Buyers still encounter the historic Sandvik wording in search and catalog language.
Is a Sandvik blade mark enough?
No. A mark is useful identification, but traceability and finished-product checks are still required.
Should old packaging be rejected?
Not automatically. Confirm whether it is legacy artwork, then align future production documents and packaging with the approved naming policy.
Which source should a specification cite?
Use the current official Alleima product page or datasheet and record the revision date used for the project.

Producer data gives material guidance, not a warranty for an unspecified finished knife. Current feasibility, compliance, quantity, lead time and sample performance require project-level confirmation.
