X10Cr13 Stainless Steel for medical instruments Product Information -:- For detailed product information, please contact sales. -: ### **Product Name:** X10Cr13 Stainless Steel for Medical Instruments **Classification:** Martensitic Stainless Steel (Surgical & Instrument Grade) --- ### **1. Overview** X10Cr13 is a **martensitic stainless steel** specifically engineered and refined for the manufacture of high-precision medical and surgical instruments. As a member of the "cutlery grade" or "instrument grade" stainless steels, it offers an optimal balance of **hardness, edge retention, corrosion resistance, and polishability**. It achieves its properties through a heat treatment process involving hardening and tempering, which allows for a wide range of final hardness levels to suit different applications. X10Cr13 is a fundamental material in the medical device industry, prized for its reliability, fabricability, and cost-effectiveness for reusable and single-use instruments that require sharp, durable edges. ### **2. Chemical Composition (Weight %, according to EN 10088-3)** Composition is tightly controlled to ensure consistent hardenability, corrosion resistance, and polishability. | Element | Minimum (%) | Maximum (%) | Notes | |---------|------------|------------|-------| | **Carbon (C)** | 0.08 | 0.15 | **Critical for hardness.** Provides the carbon necessary to form hard martensite upon quenching. Higher carbon within this range increases maximum achievable hardness. | | **Chromium (Cr)** | 12.0 | 14.0 | Provides the essential passivation layer for corrosion resistance. The lower end of the stainless spectrum, sufficient for many medical environments but not for prolonged exposure to saline or aggressive chemicals. | | **Silicon (Si)** | ≤ 1.00 | | Deoxidizer; improves strength. | | **Manganese (Mn)** | ≤ 1.00 | | Aids in deoxidation and hot workability. | | **Phosphorus (P)** | ≤ 0.040 | | Impurity, kept low. | | **Sulfur (S)** | ≤ 0.015 (often ≤ 0.003 for medical) | | Impurity. Very low levels are specified for medical grades to improve hot workability and polishability. | | **Molybdenum (Mo)** | *Optional/Trace* | | Not standard, but may be added in small amounts in proprietary grades to slightly enhance corrosion resistance. | | **Iron (Fe)** | Balance | | | **Key Feature:** The relatively high carbon content (for a stainless steel) and the 13% chromium define this as a **hardenable martensitic grade**. ### **3. Physical & Mechanical Properties** *Properties are highly dependent on the heat treatment (hardening and tempering) cycle.* **Typical Heat Treatment:** * **Annealed Condition (for machining):** ~ 180 HB * **Hardening:** Austenitize at **980-1050°C**, then oil quench or air cool (depending on section size). * **Tempering:** Typically tempered between **150-400°C** to achieve the desired combination of hardness and toughness. **Mechanical Properties (Tempered Condition):** * **Tensile Strength (Rm):** 700 - 900 MPa (can exceed 1000 MPa at lower tempers) * **Yield Strength (Rp0.2):** 500 - 750 MPa * **Elongation (A):** 10% - 15% * **Hardness Range (typical after HT):** * **Scalpels, Blades:** 50 - 58 HRC (High hardness for sharpness) * **Forceps, Scissors, Pliers:** 40 - 50 HRC (Balance of hardness and toughness) * **Bone Reamers, Rasps:** 45 - 52 HRC * **Modulus of Elasticity:** 215 GPa **Physical Properties (Typical):** * **Density:** 7.7 g/cm³ * **Thermal Conductivity:** 25 W/m·K * **Coefficient of Thermal Expansion:** 10.5 x 10⁻⁶ /K (20-100°C) * **Magnetic:** **Yes.** Fully magnetic in all conditions due to its martensitic structure. ### **4. Key Characteristics** * **Excellent Hardenability & Edge Retention:** Can be hardened to high levels (HRC 55+), allowing for the creation of sharp, long-lasting cutting edges crucial for surgical blades and scissors. * **Good Corrosion Resistance for Medical Use:** Sufficient for repeated sterilization (autoclaving at 121-134°C), cleaning with disinfectants, and exposure to bodily fluids. **Not suitable for permanent implantation or prolonged contact with saline.** * **Superior Polishability:** Can achieve a very high-quality, smooth, reflective surface finish, which is important for cleanliness, reduced tissue adhesion, and aesthetic appeal of instruments. * **Good Mechanical Strength & Stiffness:** Provides the necessary rigidity for precision instruments like probes, osteotomes, and needle holders. * **Good Machinability (in annealed state):** Can be readily machined, stamped, or forged into complex shapes before final heat treatment. ### **5. Product Applications** X10Cr13 is a cornerstone material for a vast array of medical and dental instruments: * **General Surgical Instruments:** Scalpels, surgical blades, scissors (tissue, suture), forceps (tissue, dressing), needle holders, retractors, clamps. * **Dental Instruments:** Excavators, scalers, curettes, forceps, mirrors. * **Orthopedic Instruments:** Osteotomes, chisels, bone rasps, reamers, mallets. * **Gynecological & Microsurgical Instruments.** * **Veterinary Surgical Instruments.** * **Reusable** is the primary domain, though it is also used for certain high-performance **single-use** instruments. ### **6. International Standards & Specifications** | Region/System | Standard & Designation | Scope / Notes | |---------------|----------------------|---------------| | **European (EN)** | **EN ISO 7153-1** | *Primary Standard.* Specification for materials for surgical instruments. Lists **X10Cr13** (1.4006) as a standard material. | | **European (EN)** | **EN 10088-3** | Technical delivery conditions for stainless steel semi-finished products. Grade **1.4006**. | | **ISO** | **ISO 7153-1** | Identical to EN ISO 7153-1. | | **USA / ASTM** | **ASTM A582 (Type 410)** | **Type 410** is the closest UNS/ASTM equivalent, though chemistry ranges may differ slightly. | | **UNS** | **UNS S41000** | For Type 410. | | **Germany (DIN)** | **DIN 1.4006** | Common material number. | | **Common Names** | **"Surgical Stainless"**, **"Instrument Grade 410"** | | **Important Note:** Medical instrument manufacturers often have **proprietary specifications** that refine the standard grades (e.g., tighter sulfur control, modified tempering) to achieve specific performance characteristics, often designated as "Custom 410" or similar. ### **7. Available Forms & Processing** * **Standard Forms:** Round and flat bar, wire, strip, sheet, and forgings – supplied in the **soft annealed** condition for fabrication. * **Fabrication Process Flow:** 1. **Machining/Forging/Stamping:** Performed in the soft, annealed condition. 2. **Hardening & Tempering (Heat Treatment):** The most critical step to achieve final properties. Performed in controlled atmosphere furnaces to prevent scaling/decarburization. 3. **Finishing:** Grinding, polishing, passivation (in nitric acid to enhance corrosion resistance), and final sharpening. 4. **Sterilization & Packaging.** ### **8. Selection Rationale** **Choose X10Cr13 when:** * Manufacturing **reusable surgical/dental instruments** requiring a hard, sharp edge. * A balance of **performance, proven history, and cost** is required. * **Magnetism is not a concern** (in fact, it can be beneficial for instrument racking). * The instrument will be **sterilized but not permanently implanted**. **Consider higher-alloy alternatives (e.g., X39CrMo17-1 / 1.4125, X105CrMo17 / 1.4125, or martensitic grades with Nickel) for:** * Instruments requiring **higher corrosion resistance** (e.g., for prolonged procedures). * Applications where **higher toughness** at a given hardness is needed. --- **Disclaimer:** This datasheet provides general information. For medical device manufacturing, compliance with stringent regulatory standards (e.g., EU MDR, FDA 21 CFR Part 820) is mandatory. Material selection, heat treatment, finishing, and biological safety must be validated according to these regulations and specific product standards (e.g., ISO 7740 for cutting instruments). Always source material with certification traceable to medical-grade standards (EN ISO 7153-1). Final instrument performance is critically dependent on precise and validated heat treatment processes. -:- For detailed product information, please contact sales. -: X10Cr13 Stainless Steel for medical instruments Specification Dimensions Size： Diameter 20-1000 mm Length <7402 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: X10Cr13 Stainless Steel for medical instruments Properties -:- For detailed product information, please contact sales. -:
