The core value of 1.2767 tool steel
Outstanding Hardness and Wear Resistance: The factory pre-hardened condition typically achieves approximately 42 HRC (adjustable range available upon request), delivering exceptional surface hardness and wear resistance. This enables prolonged endurance under high-pressure, high-friction conditions, effectively extending the service life of moulds or tools while reducing downtime costs associated with frequent replacements.
Superior through-hardening capability: Its unique alloy composition delivers exceptional quenching performance. This ensures even large-section moulds achieve core hardness and strength comparable to the surface, guaranteeing uniform properties throughout the workpiece. This prevents premature failure risks from performance gradients, making it particularly suitable for manufacturing large or complex precision moulds.
Good toughness and fatigue resistance: While maintaining high hardness, 1.2767 also offers good toughness (high bending strength) and fatigue resistance. This enables it to effectively resist cracking and plastic deformation under impact loads or cyclic stresses (such as in forging dies or stamping dies), ensuring more stable and reliable operation.
Superior polishing properties: Its uniform microstructure and high purity enable polishing to exceptionally high surface finishes (e.g., mirror-like effects). This is crucial for moulds producing plastic components demanding high surface quality (e.g., automotive lenses, light guides, transparent parts, cosmetic containers) or precision components.
Excellent dimensional stability: Following appropriate heat treatment, the material’s internal structure remains stable, minimising dimensional changes during prolonged mould usage or subsequent heat treatments to ensure product precision.
1.2767 tool steel applications | Driving Efficient Production
Leveraging these core advantages, 1.2767 tool steel excels across multiple demanding industrial sectors:
Precision injection moulds: Particularly suited for manufacturing transparent components, high-gloss surface parts, engineering plastic parts, and critical mould components such as cavities, cores, inserts, and slides where surface quality demands are paramount.
Large plastic moulds: Its excellent hardenability makes it an ideal choice for producing large injection moulds for automotive bumpers, dashboards, door panels, and similar components, ensuring high performance across the entire large mould.
Die-casting moulds: Employed in die-casting mould components demanding high wear resistance and thermal fatigue resistance.
Cold-working tools: Suitable for cutting blades, punches, dies, forming rolls, and other applications requiring high hardness and wear resistance.
Other precision tools: Such as gauges, fixtures, and other functional tools demanding high precision and durability.
Our advantages in Processing 1.2767 Tool Steel
We understand that the properties of tool steel directly impact the quality of end products and production efficiency. Therefore, throughout every stage of manufacturing 1.2767 tool steel, we implement rigorous quality management standards to ensure every batch of material is reliable:
Pure Raw Materials, Precise Proportions: High-quality raw materials undergo rigorous screening. Advanced spectrometers precisely control alloy element content (e.g., Cr, Mo, V) within extremely narrow target ranges, forming the foundation for consistent performance.
Advanced Smelting Process: Electro-slag remelting technology effectively removes impurities and non-metallic inclusions from molten steel, significantly enhancing purity, density, and isotropic properties. This ensures uniform material performance without weak points.
Precision Forging and Rolling: Optimised forging ratios and meticulous rolling processes not only achieve the required shape and dimensions but also thoroughly break down the as-cast structure. This eliminates internal defects, forming dense, uniform forging flow lines that enhance material toughness and fatigue strength.
Intelligent Heat Treatment Control: Pre-hardening treatment is pivotal. We employ computer-controlled tempering processes to precisely regulate temperatures, ensuring materials achieve specified hardness ranges (e.g., 41-44 HRC) with uniform hardness and microstructural distribution. This simultaneously relieves internal stresses, enhancing toughness and stability. The entire heat treatment process is monitored and documented.
Comprehensive Performance Testing: Every batch undergoes rigorous inspection, including: hardness testing (multi-point measurement ensures uniformity), ultrasonic flaw detection (verifies absence of harmful internal defects), metallographic analysis (validates microstructure condition and purity), and mechanical property testing where required (e.g., bending strength, impact toughness). Only products fully meeting all internal control standards (typically exceeding industry norms) are released for delivery.
Traceability and Certification: Complete production batch records and quality reports ensure full traceability. Material certificates compliant with international or industry standards are provided upon customer request.
