什么是 Cr12MoV 工具钢棒?

Cr12MoV 工具钢棒是一种冷作模具钢,其特征是碳含量为 1.45-1.70%,铬含量为 11.00-13.00%,钼添加量为 0.40-0.60%,钒强化量为 0.15-0.30%。这种合金成分在提供出色抗磨料磨损性能的同时,还能为复杂模具几何形状保持足够的韧性,按照 GB/T 1299 标准制造,等效牌号包括 AISI D2 和 JIS SKD11。

Cr12MoV 工具钢棒技术规格

该材料在 20°C 时的密度为 7.70 g/cm³,在 1020-1050°C 的奥氏体化温度下经过适当热处理后,硬度可达 58-62 HRC。回火工艺通常采用 500-550°C 的双循环,以实现硬度保持与尺寸稳定性之间的最佳平衡,按照 ASTM E228 方法测得 20-300°C 之间的热膨胀系数为 11.5 × 10⁻⁶/°C。

关键性能特征

优异的耐磨性能

高碳化铬含量赋予其优异的抗磨粒磨损性能,在冲裁和成形操作中,与传统碳素工具钢相比,模具寿命延长200-300%。钼的添加增强了二次硬化响应,而钒则贡献了细小的MC型碳化物,在滑动接触条件下抵抗颗粒脱落。

热处理过程中的尺寸稳定性

Cr12MoV表现出最小的变形特性,在完整淬火循环中线性尺寸变化限制在0.03-0.05%。这种稳定性源于均衡的碳化物分布和受控的奥氏体晶粒尺寸,使其成为热处理后公差要求在±0.01mm以内的精密模具的首选材料。

切削加工性与磨削特性

在退火状态下(硬度≤255 HBW),该材料表现出令人满意的切削加工性,使用硬质合金刀具的推荐切削速度为15-25 m/min。淬火后磨削操作使用氧化铝砂轮可达到Ra 0.2-0.4 μm的表面光洁度,不过复杂型腔几何形状通常采用电火花加工。

工业应用

冷冲压与冲裁模具

广泛用于制造级进模、复合模和传递模,加工厚度达3mm的材料。耐磨性与2800-3200 MPa抗压强度的结合,支持在汽车零部件制造中超过500,000次冲程的生产运行。

精密切削刀具

用于生产剪切刀片、分条刀和圆盘切刀,在这些应用中,刃口保持性直接影响切割质量。与常规高速钢相比,钒碳化物在长时间使用中保持刃口几何形状,将重磨频率降低40-60%。

塑料注射模具

被选用用于加工玻璃纤维增强热塑性塑料和磨蚀性填充化合物的模具型腔。该材料可承受高达180 MPa的注射压力,同时在超过100万次注射的生产周期内将型腔尺寸保持在±0.02mm以内。

热处理工艺指南

退火规程

在840-860°C下进行去应力退火,并以不超过20°C/小时的速率随炉冷却,可获得207-241 HBW的均匀硬度。此状态优化了可加工性,同时为最终热处理前的粗加工操作提供了足够的韧性。

淬火与回火程序

在1020-1050°C下进行奥氏体化,每25mm截面厚度保温15-25分钟,随后进行油淬以实现马氏体转变。在500-550°C下进行两次各2小时的循环回火,将残余奥氏体含量稳定在5%以下,确保使用期间的尺寸可预测性。

质量保证与测试

材料验证包括按ASTM E415进行的光学发射光谱分析以确认化学成分,按ASTM A388进行的超声波检测以验证内部健全性,以及按ASTM E407进行的显微组织评估以评定碳化物分布均匀性。力学性能验证包括按ASTM E18进行的洛氏硬度测试,以及使用室温下无缺口夏比试样进行的冲击韧性评估。

常见问题

最小起订量(MOQ)是多少?

标准最低起订量定为每种规格 500 kg,以确保通过受控热处理批次实现经济加工。定制尺寸和特定力学性能要求可能需要将最低起订量调整为 1000 kg,以满足专业制造规程和质量验证程序。

你们提供材质测试证书吗?

每次发货均随附全面的钢厂测试证书,记录按炉号进行的化学成分分析、包括硬度和晶粒度测量在内的力学性能验证,以及尺寸检验报告。对于需要按照 ASTM A1058 标准进行独立验证的关键应用,可应要求提供由认可实验室出具的第三方认证。

典型交货时间是多少?

直径从 16mm 到 300mm 的标准圆钢库存,在订单确认后 15-20 个工作日内发货。需要特定热处理条件或非标准尺寸公差的定制尺寸,通常需要 35-45 天,以配合生产排程和质量保证程序。

你们能按定制尺寸切割吗?

可提供精密切割服务,长度达 6000mm 时公差为 ±0.5mm,采用可最大限度减少热影响区的砂轮切割方法。通过优化切割参数,表面脱碳层深度控制在 0.1mm 以下,并可提供额外的无心磨削服务,为关键应用实现 ±0.02mm 的直径公差。

Acceptable Quality with Initial Documentation Delay
Purchased 500 kg minimum order of Cr12MoV bars (mixed sizes 40-80mm diameter) for our tool room inventory. Material quality met AISI D2 equivalent specifications after independent lab verification. Hardening trials achieved target 59 HRC consistently. Initial shipment arrived without complete EN 10204 3.1 certificates, causing 5-day project delay, but supplier expedited corrected documentation and offered 8% discount on next order as compensation. Machinability in annealed condition was average at 238 HBW. Material now performing adequately in cutting tool applications. Issue resolved professionally, willing to continue business relationship.

Perfect for High-Volume Stamping Operations
Ordered 1100 kg of Cr12MoV round bars (90mm diameter, 6000mm length, precision cut to ±0.5mm tolerance) for progressive die manufacturing in automotive sector. Material exhibited exceptional wear resistance in our application stamping 1.5mm thickness galvanized steel. After 520,000 production strokes, die edges showed less than 0.02mm wear using optical measurement. Heat treatment response was predictable and uniform across all pieces. Supplier's ISO 9001:2015 certification and detailed mill test certificates including Rockwell hardness mapping provided confidence for our quality management system. Repeat customer.

Solid Performance for Transfer Dies
Bought 700 kg of Cr12MoV bars (diameter 70mm, cut to 500mm lengths) for transfer die components. Material performed well in our blanking operations processing electrical steel laminations. Hardness uniformity was good at 58-60 HRC after heat treatment. Compressive strength testing showed 2950 MPa, supporting high-tonnage press operations. Lead time was 25 days, slightly longer than quoted 20 days, but quality compensated. Grinding characteristics were satisfactory using ceramic wheels, achieving Ra 0.35 μm surface finish. Would order again for similar applications.

Superior Dimensional Stability for Precision Molds
Procured 1500 kg of Cr12MoV blocks (pre-machined to 200mm x 300mm x 500mm) for precision plastic mold bases. Dimensional change after complete hardening cycle measured only 0.04%, allowing us to maintain ±0.01mm tolerances on critical features. Microstructure evaluation per ASTM E407 showed uniform carbide distribution with no banding. Molds produced electronic connector components with cavity dimensions stable over 1.2 million shots. Supplier provided excellent technical consultation on tempering parameters to minimize retained austenite below 4%. Third shipment confirms consistent quality.

Good Value Cr12MoV for Cutting Tools
Ordered 600 kg of Cr12MoV bars (various diameters 30-60mm) for shear blade manufacturing. Chemical composition analysis matched specifications, vanadium content at 0.22% provided good secondary hardening. Price was competitive compared to three European suppliers we contacted. Hardening results consistent at 59-61 HRC. Minor surface decarburization of 0.15mm depth required additional grinding allowance, but supplier promptly adjusted future orders. Blades showed 50% longer edge retention versus our previous D2 steel source. Delivery in 22 days was acceptable.

Outstanding Quality for Plastic Mold Cavities
Purchased 1200 kg of Cr12MoV flat bars (50mm x 150mm cross-section) for injection mold production. Material exhibited excellent machinability in annealed condition at 241 HBW. Ultrasonic testing per ASTM A388 showed zero internal defects. We processed molds for glass-fiber reinforced nylon, and dimensional stability was impressive - cavity dimensions held within ±0.015mm after 800,000 injection cycles at 160 MPa pressure. Surface finish after EDM and polishing reached Ra 0.3 μm. This is our fourth purchase in 18 months.
