4037 Stainless

4037 Stainless

Quick look

  • Hardness window: 55–57 HRC when ice-hardened.
  • Toughness: Higher carbon than 4034; still forgiving enough for daily resets.
  • Corrosion profile: Built for Solingen sanitation routines—excellent stain resistance.
  • Weight/feel: Dense forged blanks deliver smooth, confident closures.

Why it matters

Also sold as X65Cr13, 1.4037 brings more carbon to the classic Solingen recipe. That extra hardness translates into longer edge life while keeping the stainless behavior stylists expect from German shears. Think of it as the sweet spot between 4034 starter steels and premium 440-series alloys.

Shear pairing & edge compatibility

  • 6.0–6.5 in bevel workhorses: Perfect for barbers who need crisp scissor-over-comb with predictable bite.
  • Semi-convex salon shears: Offers enough hardness for gentle slide work without the brittleness of cobalt.

Technique map

  • Precision wet cutting, bobs, and layering on medium to thick hair.
  • Salon rotations that demand consistent performance between disinfectant dips.
  • Detail work on men’s grooming where micro-serrated options still need stainless resilience.

Real-world stress tests

  • Edge retention: Count on roughly 700–1,000 salon cuts (~4–6 weeks at 25 cuts/day). Phi-Motion cites the higher carbon (0.58–0.70%) and 54–57 HRC potential, giving a measurable boost over 4034.
  • Impact/drop resilience: Rolls more than it chips; sharpeners can restore the apex with minimal stock removal.
  • Weight & in-hand feel: At ~7.7 g/cm³ density it provides a stable, grounded feel ideal for longer blades.

Maintenance notes

Rinse, dry, and oil pivots daily to protect the martensitic structure from chemical fatigue. Set tension on the firm side to keep the harder blades tracking. Plan on professional sharpening every 3–4 months in busy shops.

Industry snapshot

  • Jaguar Silver Line Friodur® shears: Ice-hardened Solingen stainless in this range delivers long life and corrosion resistance for high-volume barbers.

Trade-offs

  • Glide is smoother than 4034 but still behind VG-10 or ATS-314 for dry slide artists.
  • Requires disciplined sanitation—chlorides left overnight can spot even stainless alloys.
  • Harder matrix can feel “stiff” until broken in; expect a short adjustment period after service.
