High-Grade Stainless Steel & Metallurgical Superiority

At Olfen Industries, quality begins with precise raw material selection. The metallurgical composition of the steel directly dictates blade edge sharpness, tension consistency, rust resistance, and structural longevity. Designed for professional salon, barber, and aesthetic applications, our instruments are manufactured strictly from premium-grade stainless steel alloys, engineered to withstand high moisture environments, repeated chemical sterilization, and rigorous everyday professional use.

Different beauty tools demand specific steel properties. Barber shears require high carbon ratios for ultra-sharp convex edges and maximum hardness (HRC), whereas eyelash extension tweezers demand non-magnetic, corrosion-resistant austenitic steel with optimum flexibility. Olfen Industries works with verified steel suppliers to guarantee absolute purity, uniform grain structure, and complete batch traceability.

Material Portfolio

Primary Steel Alloys Utilized in Our Production

We supply international distributors and private-label brands with a wide choice of steel formulations tailored to target retail price points and performance requirements.

Japanese 440C Stainless Steel

Hardness: 58-62 HRC | High-Carbon Martensitic

Widely regarded as the benchmark for premium hair dressing shears and convex edge barber scissors. High carbon content allows razor-sharp hand-honed edges with exceptional wear resistance.

Superior edge retention & smooth cutting feel
High chromium percentage for anti-corrosion protection
Ideal for high-end professional stylist scissors

AISI 420 / J2 Stainless Steel

Hardness: 52-56 HRC | Surgical Grade Alloy

A highly durable surgical stainless steel utilized extensively for cuticle nippers, nail cutters, pet grooming shears, and standard salon hairdressing scissors.

Excellent rust-proof performance in damp environments
Easy to resharpen and maintain
High tensile strength resisting structural flex

AISI 304 Non-Magnetic Steel

Austenitic Stainless | High Ductility

Specially selected for eyelash extension tweezers, eyebrow tweezers, and delicate facial tools where magnetic interference must be completely eliminated.

Zero magnetic retention for handling micro-lashes
Resistant to strong salon disinfectants & autoclaves
Lightweight with ideal tip tension memory

Precision Manufacturing

Heat Treatment & Surface Finishing Standards

Raw steel alone does not guarantee a world-class tool. Our controlled thermal processing and hand-finishing techniques unlock the steel's maximum mechanical properties.

1 Vacuum Heat Treatment & Cryogenic Tempering

Blades undergo automated vacuum heat treatment followed by sub-zero cryogenic freezing down to -120°C. This process refines the steel's internal crystalline structure, eliminating residual stress and guaranteeing uniform Rockwell hardness across the entire cutting blade.

2 Multi-Stage Anti-Corrosion Testing

All finished stainless steel instruments undergo rigorous quality control inspections, including 24-hour salt spray testing and repeated steam autoclave cycles to verify total resistance against rust, oxidation, and pitting.

3 Advanced Surface Coatings (PVD & Plasma)

In addition to mirror polishing and satin matte finishes, we offer protective color coatings such as Physical Vapor Deposition (PVD) Titanium coating in Blue, Gold, Rainbow, and Matte Black. These coatings increase surface hardness while protecting tools from harsh chemical exposure.

4 Ergonomic Weight & Balance Calibration

Every tool is forged and ground to achieve optimal center-of-gravity distribution, minimizing hand fatigue for barbers, hairdressers, and lash technicians during prolonged daily use.
