Sandvik 19C27 Strip Steel Product Information -:- For detailed product information, please contact sales. -: ## **Sandvik 19C27 Strip Steel – High-Carbon Martensitic Stainless Steel for Wear-Resistant Components** ### **Product Overview** Sandvik 19C27 is a specialized **high-carbon, high-chromium martensitic stainless steel strip** engineered for applications requiring exceptional wear resistance, moderate corrosion protection, and high hardness in through-hardened condition. Positioned between standard cutlery grades and specialized tool steels, 19C27 offers an optimal balance of hardness, carbide formation, and stainless properties for demanding industrial components subjected to abrasive wear and mechanical stress. ### **Key Advantages** * **Superior Wear Resistance:** High carbon content combined with chromium carbides provides excellent resistance to abrasive and adhesive wear. * **High Hardness Potential:** Can achieve hardness levels up to 60-62 HRC through proper heat treatment, suitable for demanding tooling applications. * **Good Corrosion Resistance:** Offers better corrosion resistance than tool steels like D2 or A2 due to higher chromium content, suitable for humid or mildly corrosive environments. * **Good Dimensional Stability:** Exhibits relatively low distortion during quenching compared to some high-alloy tool steels. * **Optimized Carbide Structure:** Controlled manufacturing produces a uniform distribution of carbides for consistent performance. ### **Chemical Composition (Typical, wt%)** The composition is balanced to form hard chromium carbides while maintaining adequate corrosion resistance. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Carbon (C)** | 0.90 - 1.00 | **Chromium (Cr)** | 13.0 - 15.0 | | **Silicon (Si)** | 0.30 - 0.60 | **Manganese (Mn)** | 0.30 - 0.60 | | **Molybdenum (Mo)** | 0.40 - 0.70 | **Vanadium (V)** | 0.10 - 0.20 | | **Sulfur (S)** | ≤ 0.015 | **Phosphorus (P)** | ≤ 0.025 | | **Iron (Fe)** | Balance | | | *Note: The elevated carbon (>0.9%) enables high hardness, while molybdenum and vanadium additions refine grain size and improve toughness.* ### **Physical & Mechanical Properties** #### **Properties in Annealed Condition (as supplied strip):** * **Density:** 7.7 g/cm³ * **Modulus of Elasticity (E):** 200 GPa * **Hardness:** 200-230 HB * **Tensile Strength:** 700-850 MPa * **Yield Strength:** 550-700 MPa * **Elongation:** 10-15% * **Microstructure:** Spheroidized carbide structure in ferritic matrix #### **Properties after Hardening & Tempering:** * **Recommended Austenitizing:** 1010-1040°C * **Quenching:** Oil or forced air * **Tempering Range:** 180-250°C for maximum hardness * **Achievable Hardness:** **58-62 HRC** * **Tensile Strength:** 2100-2400 MPa * **Compressive Strength:** ~3000 MPa * **Toughness:** Moderate for achieved hardness level #### **Corrosion Resistance:** * Resists atmospheric corrosion, water, steam, and mild chemicals * Superior to conventional tool steels in humid environments * Not suitable for severe chemical or marine applications ### **International Standards & Approvals** * **Sandvik Proprietary Grade:** **19C27** * **Similar/Equivalent Standards:** * **EN / DIN:** 1.4108 / 1.4034 (X90CrMoV18) * **AISI:** 440C modified * **UNS:** S44004 * **ISO 4957:** Tool steels - Stainless * **Industry Specifications:** Recognized in tooling and component manufacturing sectors ### **Product Applications** #### **Cutting & Slitting Applications:** * Industrial cutting blades for paper, textiles, and plastics * Slitter knives for metal and non-metal materials * Guillotine blades for soft materials * Food processing blades #### **Tooling & Wear Components:** * Plastic injection mold components (cores, cavities, ejector pins) * Die components for forming and stamping * Wear plates and guides * Measuring instruments and gauges * Valve seats and seals #### **Industrial Components:** * Pump shafts and sleeves * Bearing races and components * Fastener manufacturing tools * Textile machinery components #### **Specialty Applications:** * Surgical and dental instrument components * High-wear fasteners * Precision mechanical components requiring wear resistance ### **Processing Guidelines** #### **Forming & Machining:** * **Annealed State:** Good machinability (approximately 60% of free-cutting steel) * **Forming:** Limited formability in annealed state; suitable for simple bending * **Machining Parameters:** Use sharp carbide tools with positive rake angles * **Grinding:** Responds well to precision grinding operations #### **Heat Treatment:** 1. **Preheating:** 750-800°C to reduce thermal shock 2. **Austenitizing:** 1010-1040°C (depending on desired hardness/carbide solution) 3. **Quenching:** Oil quench preferred for maximum hardness 4. **Tempering:** Immediate tempering at 180-250°C for 2+ hours (double tempering recommended) 5. **Sub-zero Treatment:** Optional for maximum dimensional stability and hardness #### **Recommended Heat Treatment Cycle:** ``` Preheat: 800°C → Austenitize: 1025°C (30 min/inch) → Oil quench to 50°C → Temper: 200°C (2+2 hours) ``` #### **Welding & Joining:** * **Weldability:** Poor; requires pre-heat (300°C) and post-weld heat treatment * **Recommended:** Avoid welding if possible; use mechanical fastening instead #### **Surface Treatment:** * Accepts most common surface treatments * Can be polished to high surface finishes * Suitable for PVD/CVD coatings for enhanced performance ### **Availability** * **Thickness Range:** 0.5 mm to 6.0 mm * **Width Range:** Up to 330 mm * **Temper Conditions:** Annealed (soft) * **Surface Finish:** 2B, BA, or custom finishes * **Dimensional Tolerances:** To EN 10151 or equivalent standards * **Packaging:** Coils or sheets with protective coating ### **Technical Considerations** #### **Design Recommendations:** * Avoid sharp corners and sudden section changes * Maintain uniform wall thickness where possible * Consider allowance for heat treatment distortion #### **Quality Assurance:** * Micro-cleanliness control * Decarburization-free surfaces * Uniform carbide distribution * Traceability maintained throughout production #### **Safety & Handling:** * Material becomes extremely hard after heat treatment * Use appropriate PPE during machining and handling * Store in dry conditions to prevent surface corrosion --- **Application Note:** 19C27 is best suited for applications where its combination of wear resistance and moderate corrosion resistance provides advantages over conventional tool steels or standard stainless grades. For optimal results, component design should consider the material's characteristics and heat treatment requirements. **Technical Support:** Sandvik provides comprehensive technical support for 19C27, including heat treatment recommendations, processing guidelines, and application engineering assistance.
