4037 Stainless
4037 stainless refers to the European material number 1.4037, X65Cr13, a hardenable martensitic chromium steel. Its documented carbon range is higher than 1.4034’s, while finished-scissor performance still depends on the particular tool. Keep producer chemistry, processing hardness and a maker’s model specification separate when evaluating a product claim.

Quick look
- Identity: 1.4037 / X65Cr13; retain the complete designation and source.
- Chemistry: The selected DEW sheet reports carbon and chromium ranges plus a sulfur maximum.
- Hardness: The producer’s conditional processing guidance does not establish a universal 55–57 HRC scissor range.
- Comparison: A higher carbon range does not by itself prove longer service intervals or smoother slide cutting.
Composition breakdown
Deutsche Edelstahlwerke’s 1.4037 sheet gives carbon 0.58–0.70%, chromium 12.50–14.50% and sulfur at a maximum of 0.015% by mass. This page uses that exact source for its structured composition, with unlisted elements left undisclosed. The document is revision 4037-1, dated 1 August 2007, and remains hosted by Swiss Steel Group. DEW material sheet.
These values make a useful comparison with 1.4034. Rodacciai’s 1.4034 record has 0.43–0.50% carbon and the same 12.5–14.5% chromium range. The carbon ranges do not overlap. That is a source-based distinction between compositions, not a measured difference between two finished scissors. 1.4034 cast-analysis ranges.
When a supplier gives a typical or nominal point value, preserve that label instead of treating it as a specification limit. Where sources disagree, keep the selected publication visible and request the applicable supply specification. Combining the most convenient values from different producer sheets can create a chemistry record that no producer actually published.
Why it matters
A material document may show a supplied condition, a processing recommendation and properties for different applications. Read the heading and footnotes before using a number in a buying comparison.
The DEW sheet says hardness should not exceed 60 HRC after hardening and stress relieving at 200°C. It also reports a soft-annealed value of ≤245 HB, with dimensional and straightening qualifications. Neither entry establishes the previous 55–57 HRC claim for every 4037 hair scissor. No conversion between the two scales is provided here. Processing context.
For a finished pair, ask whether the maker publishes hardness for that exact model and where the statement applies. A seller’s number without a scale, model or condition should remain an unresolved claim. A precise-looking figure is only useful when it describes the object being compared.
Shear pairing & edge compatibility
Use the blade and handle design to identify the intended work. A 4037 label does not establish a bevel angle, convex profile, serration pattern, blade length or whether a model suits slide cutting. Those details belong in the model specification and service record.
| Evidence level | Example | What to check next |
|---|---|---|
| Material designation | 1.4037 / X65Cr13 | Which producer and specification apply? |
| Supplied product | Strip, bar or another form | What condition and dimensions accompany the property? |
| Finished scissors | Named model and variant | What edge, hardness and intended use does the maker state? |
| Service result | Work completed on one pair | Were geometry, action and the reported symptom checked? |
A service provider familiar with a country of manufacture is not automatically qualified for every edge or adjustment system made there. Discuss the actual construction and proposed work before booking a service.
Technique map
For wet cutting, layering, scissor-over-comb or detail work, start with the maker’s intended use and the fit of the finished tool. A useful comparison names the models, edge profiles and task instead of arranging national steel labels into a performance ladder.
During a trial, record how each pair handles the same task and whether either required an adjustment. Keep those observations as evidence about those pairs. Without a controlled test, a difference in cutting feel cannot be assigned exclusively to carbon content or steel hardness.
Performance evidence
No reviewed source establishes that 4037 scissors survive drops by rolling rather than chipping, recover with minimal stock removal, or require a material-specific break-in period. An impact or new closing resistance calls for inspection of the actual pair. It does not diagnose the steel’s failure mode.
DEW’s corrosion description is qualified by environment, heat-treatment condition and surface finish. Its discussion of chloride-free media does not validate a salon immersion process. Check the exact maker’s compatibility instructions for the cleaning product in use. Material corrosion context.
Maintenance notes
Follow the maker’s instructions for cleaning, lubrication and tension. Jaguar, for example, links persistent poor cutting after cleaning, oiling and correct adjustment to the need for professional maintenance. That gives an assessment sequence for its scissors; it does not establish a sharpening calendar for 1.4037. Jaguar care guidance.
Report any impact, service history and change in behavior when requesting help. Ask the provider to preserve the model’s intended edge and explain any repair limits. Repeatedly tightening a poorly cutting pair is not a substitute for identifying why it is cutting poorly.
Industry snapshot
Zapp’s precision-strip linecard lists 1.4037 with X65Cr13 among its martensitic grades. This confirms a documented supply category, not a particular barber-scissor application. Producer linecard.
A useful naming example comes from Alleima Print EPS, a hardened and tempered strip for printing doctor blades. Alleima marks 1.4037 and X65Cr13 as nearest equivalent grades. Its nominal chemistry and informative 550 ±25 HV hardness belong to that named strip product. They are not a generic 1.4037 recipe, a hair-scissor hardness measurement or a reason to relabel another brand’s material. Print EPS datasheet.
The earlier association of Jaguar Silver Line/Friodur with a specific 4037 chemistry is not established by the reviewed primary material sources. A treatment name or product family should be linked to an alloy only when the maker supplies that link.
Trade-offs
Choose between documented scissor models using fit, edge design, intended technique, service access and cost alongside the material record. A higher-carbon designation can be useful identification information. The claimed advantage still needs evidence for the finished tool, especially when a seller promises longer edge life or a particular cutting feel.

Frequently Asked Questions
4 answers you can open one at a timeHow does 1.4037 differ from 1.4034?
The selected producer records give 1.4037 a higher carbon range: 0.58–0.70% versus 0.43–0.50% for 1.4034. This composition difference does not by itself establish longer edge life for a finished scissor.
Are all 4037 scissors 55–57 HRC?
No. The reviewed DEW sheet gives condition-specific processing guidance, not a universal scissor range. A finished model needs its own hardness evidence, with the scale and scope retained.
Is Alleima Print EPS exactly the same material as 1.4037?
Alleima describes 1.4037 as a nearest equivalent for Print EPS. Keep that qualifier: the named printing-strip product’s chemistry and Vickers hardness should not be transferred to an unidentified hair scissor.
Does 4037 need a tighter tension setting or fixed sharpening schedule?
Neither follows from the grade name. Use the exact maker’s adjustment and care instructions, and seek assessment for persistent cutting problems rather than imposing a material-based tension setting or service calendar.
