Klein

What Klein does

Klein srl is an Italian specialty metals supplier headquartered in Pioltello (Milan), operating since 1994 as the Italian subsidiary of Klein SA. The company manufactures and distributes precision stainless steel wire and bars, titanium products (Grades 2, 4, 5, and Grade 5 with Niobium), stainless and tempered steel strips, and specialty alloys including CoCr28Mo for medical implants and ARCAP copper-nickel-zinc for watchmaking and optical fiber connectors.

Klein's technical differentiation centers on ultra-precision manufacturing: drawn and ground wire produced to ISO h5 diameter tolerance, stainless steel strips as thin as 0.03 mm, and laser-controlled edge banding achieving +/- 0.02 mm width tolerance. The proprietary KLEINOX, KLEITOR, KLEIN C 100, and ARCAP grade series span martensitic, austenitic, free-cutting, and non-ferrous alloy chemistries. The company holds ISO 9001 quality certification and a portfolio of medical-grade material certifications (ASTM F67, F136, F1295, F1537, F138; ISO 5832-2/3/11/12), enabling supply into surgical implants, dental, and aerospace applications. Production relies on a 2020-commissioned laser-controlled edge banding machine among other specialized equipment.

Klein operates a B2B direct sales model with quote-based pricing on specialty materials, serving seven vertical markets: medical/healthcare (primary), watchmaking and jewelry, spring and blade production, eyewear, automotive, industrial manufacturing, and precision turning/micromechanics. Customers are reached via the multilingual company website, LinkedIn, industry trade shows (Mecspe), and direct sales contact. With 11-50 employees, ten-year supply relationships with German steel producers, and both domestic (Italian) and international customer reach, Klein occupies a niche specialty-metals position anchored in regulated, precision-demanding end markets. The founder Federico Klein remains the company's owner.

Core offering

Klein manufactures and supplies ultra-precision stainless steel and titanium drawn and ground wires and bars (diameter from 1.00 mm) and stainless steel strips (thickness from 0.03 mm) for medical, watchmaking, automotive, eyewear, and electromechanical industries. The portfolio spans proprietary grades (KLEINOX, KLEITOR, KLEIN C 100) plus titanium Grades 2/4/5 and specialty alloys such as CoCr28Mo and ARCAP AP 1D, produced under ISO 9001 with medical-grade material certifications.

Product overview

Klein is a manufacturer and supplier of high-precision stainless steel and titanium wires, bars, and strips. The product portfolio centers on four core offerings: stainless steel wire and bars (KLEINOX series, KLEITOR series, 100Cr6), titanium products (Grades 2, 4, 5, and Grade 5 with Niobium), stainless and tempered steel strips (KLEIN C 100, KLEINOX 4028), and specialty alloys including CoCr28Mo for medical implants and ARCAP AP 1D for watchmaking. The KLEINOX series encompasses martensitic, austenitic, and precipitation-hardening stainless steels serving medical, automotive, watchmaking, textile, and precision engineering industries. Products are manufactured with tight tolerances (down to ISO h5 for wire) and thicknesses from 0.03 mm for strips. Klein operates as ISO 9001 certified manufacturer, established in 1994 as the Italian subsidiary of Klein SA.
