Cr12MoV 밀링 플레이트 배치가 페루로 향합니다

지난주에 저희는 주문을 받았습니다. Cr12MoV milled plates from a customer in Peru. Coincidentally, we had the material in stock, and within less than a week, we arranged the shipment, and it was on its way.

We take South America seriously, and Peru in particular is one we’ve been actively working to grow. On-the-ground conditions make it a natural fit. Import duties on tool steel under HS codes 72284000 and 72283000 are currently zero, and under the China-Peru Free Trade Agreement, we can issue a Form R certificate of origin for shipments like this one, which helps our customers clear customs smoothly and keep landed costs down.

The video below shows that shipment being lifted and loaded, with Cr12MoV milled plates heading to Peru. It’s a quick turnaround story, but it also shows why Cr12MoV remains a steady seller in this market, and what buyers should know about the grade.

Cr12MoV란 무엇인가

Cr12MoV is a high-chromium cold-work tool steel defined by the Chinese GB/T 1299 national standard. It belongs to the same broad family as AISI D2, JIS SKD11, and DIN 1.2379, and in practice we position it as a D2를 대체할 수 있는 비용 효율적인 대안. 화학적 조성은 완전히 동일하지는 않습니다. D2는 일반적으로 몰리브덴과 바나듐 함량이 약간 더 높지만, 전반적인 성능 프로필은 매우 유사하여 Cr12MoV는 기존에 D2가 사용되던 대부분의 응용 분야를 훨씬 낮은 비용으로 대체할 수 있습니다.

핵심 성과 강점

Cr12MoV owes its wear resistance to a dense chromium carbide network throughout its microstructure, which withstands severe abrasive loading. The molybdenum and vanadium additions give the steel good hardenability for its alloy class, capable of developing a solid hardness profile in medium- to large-cross-section dies, though buyers working with very heavy sections should still confirm hardenability against their specific geometry, since Cr12MoV’s Mo and V content runs lower than D2. It also holds its shape well after heat treatment, with minimal volume change during quenching and tempering, which matters for complex tool geometries that need to stay dimensionally accurate.

Cr12MoV는 Cr12 계열 내에서 뚜렷하게 정의된 성능 범위의 중간에 위치합니다. Cr12 itself carries the highest carbon content, between 2.00 and 2.30 percent, but without molybdenum or vanadium, it suffers from carbide segregation and comes out brittle with limited toughness. Cr12MoV lowers carbon to 1.45 to 1.70 percent and adds Mo and V, which refine the carbide structure and significantly improve toughness and hardenability while keeping wear resistance intact. For readers doing deeper grade comparisons, Cr12Mo1V1 Cr12MoV보다 한 단계 위에 있는 이 합금은 몰리브덴과 바나듐 함량이 더 높고 화학적 성질이 D2에 더욱 가깝지만, 일반적인 공구 제작 작업에는 흔히 사용되지 않는 등급입니다.

일반적인 적용 사례

Cr12MoV is widely used for cold stamping dies, cold heading dies, drawing dies, blanking dies, and shearing blades. For shipments like the recent Peru order, this makes it a strong fit for the region’s metalworking sector. Stamping plants across Latin America often run high-cycle operations on heavy-duty sheet metals, sometimes with heat-treating infrastructure that varies from shop to shop. Cr12MoV’s toughness and quench stability help these tools resist premature cracking and edge chipping, resulting in more reliable production runs for the buyer.

밀링 가공된 판재의 가치

Black surface, or hot-rolled raw plate, retains the rough, oxidized, decarburized scale left by the mill. Milled plate has been precision face-milled to strip that layer away entirely, exposing clean, sound tool steel underneath.

밀링 가공된 판재를 선택하는 구매자는 처음부터 평평하고 평행한 소재를 얻을 수 있습니다. 이는 원자재 낭비를 줄이고, 마그네틱 척의 설정 시간을 단축하며, 작업자가 황삭 가공을 건너뛰고 바로 정삭 가공으로 넘어갈 수 있도록 합니다. 아오보 스틸은 두께 공차 0/+1mm로 밀링 가공된 판재를 공급합니다. 이는 최종 정밀 가공에 필요한 최소한의 재료만 남겨두고 불필요한 무게에 대한 비용을 지불하지 않아도 될 만큼 정밀한 가공을 가능하게 합니다.

열처리 지침

Standard quenching for Cr12MoV is carried out at 950°C to 1000°C in oil, followed by tempering. GB/T 1299 sets a minimum post-treatment hardness of 58 HRC, and in practice this route commonly achieves 58 to 61 HRC, covering most stamping, blanking, and shearing die applications.

A high-temperature quench followed by multiple tempering cycles in the 510°C to 520°C range, the secondary-hardening route typically associated with higher-alloy grades like D2, can also be applied to Cr12MoV, but the hardness gain from secondary carbide precipitation will be less pronounced given its lower Mo and V content. Buyers targeting hardness above 61 HRC or planning to use this route should confirm feasibility with their heat treater or with Aobo Steel before committing to a die design around it.

As always, adjust actual parameters for the specific die geometry, section thickness, design complexity, and the mechanical stresses the tool will face in service.
