常见问题

最小起订量(MOQ)是多少?

我们对35CrMo合金钢棒的标准最小起订量为每种规格5公吨。对于40mm-150mm的库存直径尺寸,我们可以接受从1公吨起的较小试订单,价格会有所调整。对于需要多个直径范围的客户,可提供混装集装箱装载。

35CrMo合金钢棒制造商

你们提供材料测试证书吗?

是的,我们为每次发货提供全面的材料测试证书,包括EN 10204 3.1钢厂测试证书。文件包括化学成分分析、拉伸测试结果、指定温度下的冲击韧性值以及硬度测量。可根据要求安排SGS、BV或TUV的第三方检验服务。

典型的交货时间是多少?

对于淬火和回火状态的标准库存尺寸,交货时间通常为订单确认后15-20个工作日。定制直径要求或特殊热处理规格可能会将交货时间延长至25-35个工作日,具体取决于生产排程。紧急需求可提供加急处理服务,需支付加急制造费用。

能否按定制尺寸切割?

我们提供精密切割服务,长度规格公差为±5mm。我们的工厂配备自动化锯切设备,能够加工直径达300mm的棒材。可提供定制长度切割、倒角和中心钻孔服务。对于需要严格尺寸公差的应用,我们提供直径公差为h9或更优的车削和抛光棒材。

Premium 35CrMo for Mining Equipment Components
Sourced 9 tons of 35CrMo alloy steel bars (90mm and 110mm diameters, 8-meter lengths) for mining crusher shaft applications. Material certificates documented carbon 0.38%, chromium 1.05%, molybdenum 0.22% - optimal composition for our heat treatment process. Ultrasonic testing results showed zero internal defects. Impact toughness at -40°C exceeded 35J, critical for our cold climate operations. Custom center drilling service saved significant machining time. Delivery in 19 days including container consolidation with another product line. Engineering support team provided valuable tempering temperature recommendations for achieving HRC 32-36 hardness range.

Acceptable Quality with Delivery Delay Resolved
Ordered 7 tons of 35CrMo bars (75mm diameter) for excavator arm pin manufacturing. Initial delivery was delayed by 8 days due to production scheduling issues, but supplier communicated proactively and offered partial shipment option. Material quality met GB/T 3077 standards with tensile strength 1010 MPa. Two bars had minor surface pitting that required additional machining allowance. Supplier provided compensation for delay and quality concern. Final product performance in field testing has been satisfactory. Would consider ordering again with earlier lead time planning.

Reliable 35CrMo Bars at Competitive Pricing
Purchased 5 tons of 35CrMo round bars (40mm diameter) for gear shaft production. Compared quotes from four suppliers - this offer provided best value including processing services. Material test certificates showed yield strength at 850 MPa with elongation 13%. Turned and polished finish option delivered h9 tolerance as specified. Packaging was adequate though one bundle had loose strapping upon arrival. Technical documentation comprehensive including heat treatment curves. Good choice for medium-volume production runs where cost efficiency matters.

Perfect Material for Propeller Shaft Applications
This is our fourth purchase of 35CrMo alloy steel bars for marine propeller shaft manufacturing. Latest order was 10 tons (150mm diameter, quenched and tempered condition). Consistency between batches is remarkable - chemical composition variance less than 0.02% across all elements. Vacuum degassing treatment ensures excellent purity with non-metallic inclusion rating of Grade A. Machining characteristics are superior with minimal tool wear. Lead time was 17 days including custom length cutting to 4.5 meters. Highly recommended for critical marine drivetrain components.

Good Value 35CrMo Material for Hydraulic Systems
Ordered 6 tons of 35CrMo bars (50mm diameter, 6-meter lengths) for hydraulic cylinder rod applications. Chemical composition analysis matched DIN 17200 requirements with sulfur and phosphorus both below 0.030%. Hardness uniformity was good at HB 280-310 range. Delivery took 22 days, slightly longer than quoted 20 days. Pricing was competitive compared to three other European suppliers. Minor surface marks on two bars but within acceptable tolerance. Overall solid material for our engineering projects.

Superior Quality for Crankshaft Production
We purchased 12 tons of 35CrMo alloy steel bars (80mm and 100mm diameters) for crankshaft manufacturing. EN 10204 3.1 certificates showed chromium at 0.95% and molybdenum at 0.20%, perfectly within specification. The quenched and tempered condition delivered yield strength of 865 MPa. Straightness tolerance was impressive at less than 2mm per 6 meters. Technical support team provided excellent heat treatment recommendations. Third order this year - consistently reliable material for high-stress automotive components.
