热轧钢坯 | ASTM A633 C级 | 直径120mm x 长度6m

热轧钢坯是通过连铸工艺生产的基础半成品钢材,是结构钢、钢筋和线材生产中下游轧制操作的重要原材料。这些方形或矩形截面的钢坯广泛应用于建筑、汽车制造和工业加工领域,在这些领域中,具有成本效益的材料转化至关重要。我们的120mm直径钢坯按照ASTM A633 Grade C规格生产,具有优异的力学性能,抗拉强度超过485 MPa,使其成为轧机操作中要求质量稳定和尺寸精度的制造商的首选。

什么是热轧钢坯?

热轧钢坯是一种方形或矩形截面的半成品铸造产品,每边通常在100mm至200mm范围内,采用连铸技术在1,200°C以上的温度下制造。这种中间钢材形态是再轧机的主要原料,用于生产成品长材,包括螺纹钢、线材、结构型材和无缝管。

热轧钢坯技术规格

我们的ASTM A633 Grade C热轧钢坯符合严格的化学成分要求:碳含量最高0.20%,锰1.15-1.50%,磷最高0.035%,硫最高0.040%,硅0.15-0.40%。力学性能包括根据ASTM A633/A633M-01第6节规定,最小屈服强度345 MPa,抗拉强度485-620 MPa,50mm标距伸长率21%。标准钢坯尺寸为120mm × 120mm截面,长度6米,但可根据要求提供100mm至165mm方坯的定制尺寸。

制造工艺与质量控制

生产采用连铸工艺,将1,540-1,560°C的钢水浇入水冷铜结晶器,实现0.8-1.2米/分钟的凝固速率。每支钢坯均按ASTM A435进行超声波检测,以检出直径超过3mm的内部缺陷,确保后续热轧工序的结构完整性。表面质量符合ASTM A903 Grade B标准,最大允许缺陷深度为1.5mm,截面尺寸公差按ASTM A1058保持在±3mm以内。

应用与行业用途

这些热轧钢坯在混凝土结构用钢筋生产、紧固件行业用线材制造以及建筑用型钢轧制中发挥关键作用。汽车行业采用钢坯进行锻造加工,生产曲轴、连杆和变速器部件。石油和天然气行业将该材料用作无缝管制造的原料,而铁路行业则依赖钢坯进行轨道扣件生产和轮辋锻造加工。

热轧钢坯供应商

为什么选择我们的热轧钢坯

我们的生产设施通过ISO 9001:2015质量管理体系认证,确保关键合金元素的化学成分控制偏差在±0.02%以内。我们采用钢厂直销定价结构,与分销渠道相比可降低材料成本12-18%,同时我们毗邻主要航运港口的战略位置使国际目的地交货周期为18-25天。每个生产批次均附有符合EN 10204 Type 3.1的完整钢厂测试证书,记录从炉号到最终检验结果的全流程可追溯性。

常见问题

最小起订量(MOQ)是多少?

我们的标准起订量为每个规格100公吨,相当于大约一个20英尺集装箱。对于有持续需求的长期客户,我们可接受最低25吨的部分集装箱装载,并相应调整价格以反映额外的操作成本。

热轧钢坯批发

你们提供材质检测证书吗?

是的,每批货物均随附由我们的质量保证部门出具、并经SGS或Bureau Veritas等独立第三方检验机构会签的EN 10204 Type 3.1工厂检测证书。证书记录了完整的化学成分分析、力学性能测试结果、热处理记录和尺寸检验数据,以实现完整的材料可追溯性。

典型的交货时间是多久?

标准交货周期为采购订单确认后18至25天,其中包括7-10天的生产时间、3-5天的质量检验和文件准备时间,以及8-10天的海运时间(运往主要国际港口)。对于超过200公吨的订单,可提供加急生产,交货周期为12-15天。

你们可以按定制尺寸切割吗?

当然可以。我们的切割设备可满足3米至12米的定制长度要求,公差为±50mm,横截面尺寸为100mm至165mm方坯。定制切割服务会在标准生产周期基础上增加3-4天,并根据复杂程度和数量额外收取每吨15-25美元的费用。

Acceptable Quality After Initial Documentation Delay
Ordered 50 tons for wire rod trial production run. Material quality itself was satisfactory with chemistry and mechanical properties meeting ASTM A633 Grade C requirements. Tensile strength at 501 MPa and proper surface finish per specifications. Initial shipment experienced 4-day delay in mill certificate preparation which pushed our production schedule. Supplier promptly resolved documentation issues and provided expedited shipping at no additional cost. Final delivery was 27 days total. Material performed adequately in rolling trials. Fair experience overall - would consider future orders with clearer documentation timeline expectations upfront.

Superior Billets for Railway Component Manufacturing
Purchased 95 tons for rail fastener forging and wheel rim production. Material exceeded expectations with elongation testing at 24% in 50mm gauge length, well above the 21% minimum. The ISO 9001:2015 certification was evident in manufacturing consistency - heat number traceability allowed us to track each billet to specific ladle and casting sequence. Delivery to Melbourne port was 21 days including customs clearance support. Application engineering team provided complimentary analysis comparing this Grade C material versus alternative specifications for our railway applications. Outstanding technical partnership beyond just material supply.

Solid Performance for Rebar Rolling Operations
Ordered 75 tons of 120mm billets for construction rebar production in Dubai. Material performed well in our rolling mill with consistent mechanical properties throughout the lot. Tensile strength ranged 495-518 MPa across sample testing. Delivery to Jebel Ali port completed in 23 days. Documentation package was complete with ASTM A633/A633M-01 compliance verification. Only minor issue was packaging - two bundles had loose strapping upon arrival but no material damage occurred. Quality-to-price ratio is competitive for Middle East market. Would order again for standard rebar projects.

Reliable Supplier for Seamless Pipe Production
Third consecutive order, this time 200 metric tons for our seamless pipe mill serving oil and gas sector. Consistency across all three orders has been remarkable - chemical composition variance less than 0.015% for critical elements. Appreciated the expedited 14-day production schedule for this larger volume. Bureau Veritas inspection certificates documented complete dimensional compliance within ±2.5mm tolerance. Surface finish quality enables direct piercing without additional preparation. Technical sales team provided valuable consultation on optimizing billet temperature for our specific piercing mill configuration. Highly recommended for pipe manufacturing applications.

Perfect Material for Automotive Forging Applications
We procured 150 tons specifically for crankshaft forging operations. The continuous casting quality was exceptional with solidification uniformity evident in microstructure analysis. Carbon content at 0.19% and silicon at 0.28% provided ideal forgeability characteristics. Phosphorus and sulfur levels were impressively low at 0.028% and 0.032% respectively, ensuring clean steel for critical automotive components. Factory-direct pricing saved us roughly £18,000 compared to traditional distributor channels. Delivery was 20 days to our Midlands facility. This is now our preferred supplier for forging-grade billets.

Good Value Billets with Competitive Pricing
Ordered 100 tons of standard 120mm square billets for wire rod manufacturing. Price was approximately 14% lower than our regular German distributor, representing significant cost savings for our operation. Material quality was solid with yield strength at 358 MPa and elongation at 23%. Delivery took 24 days, slightly longer than quoted 18-25 day range but acceptable. Minor surface marks on 3 billets were within ASTM A903 tolerances but required additional grinding. Overall good experience for the price point. Would recommend for cost-sensitive projects.

Outstanding Quality Control and Documentation
Purchased 85 metric tons for structural section production. What impressed us most was the ultrasonic testing documentation per ASTM A435 showing zero internal discontinuities above 2.5mm. Dimensional tolerances were exceptional at ±2mm, better than the standard ±3mm specification. Mill test certificates countersigned by SGS provided complete heat treatment records and mechanical test data. Lead time was 19 days including ocean freight to Southampton. Technical support team helped us optimize material selection for our specific rolling parameters. Already planning our second order for Q2 2026.

Excellent ASTM A633 Grade C Billets for Rebar Production
Ordered 120 tons of 120mm × 120mm × 6m billets for our rebar rolling mill. Chemical composition perfectly matched specifications with carbon at 0.18% and manganese at 1.42%. Tensile strength tested at 512 MPa, exceeding the 485 MPa minimum requirement. EN 10204 Type 3.1 certificates were comprehensive with full traceability. Delivery completed in 22 days to our Singapore facility. Surface quality met ASTM A903 Grade B with no defects exceeding 1mm depth. This material significantly improved our rolling efficiency compared to previous suppliers.
