Welcome to learn about our core equipment—the 5-ton medium frequency furnace. With a 5-ton capacity, it meets small to medium-scale production needs while balancing flexibility and energy efficiency. The furnace is equipped with an intelligent control system that monitors key parameters like temperature and pressure in real time, guaranteeing the stability and consistency of every batch. Additionally, we have deep partnerships with electric arc furnace manufacturers to serve high-volume customers, such as those requiring 1.2714 mold steel, with a typical minimum order of 30 tons. Whether for small or large-scale production, we are committed to providing high-quality tool steel and being your trusted partner.

As a professional tool steel manufacturer, we are committed to providing our customers with the highest quality material solutions. Our ESR (Electroslag Remelting) equipment uses advanced technology to precisely control the melting process, effectively removing impurities and non-metallic inclusions from the steel. This significantly improves the purity and uniformity of the material. Our ESR equipment ensures excellent mechanical properties, fatigue resistance, and durability, whether it’s high-hardness, wear-resistant tool steel, or special alloy steel for demanding conditions. With a focus on innovation and strict quality standards, we deliver reliable high-end tool steel products to help industries achieve top performance and efficiency.

Electroslag Remelting

We understand that high-quality mold steel starts with precise forging processes. Our experienced forging team can meticulously control every detail of the process to meet customer requirements, ensuring products with excellent mechanical properties and dimensional accuracy.

Whether you require small, precision mold steel components or large mold steel parts, we are here to provide professional forging solutions tailored to your specific needs.

In processing tool steel plates, we use high-precision milling and finishing equipment to ensure optimal surface flatness, smoothness, and dimensional accuracy. Our milling equipment is equipped with advanced CNC systems, enabling efficient and precise processing to meet the needs of various mold steel materials. Our machines operate reliably for large plates or small precision components, ensuring that every mold steel plate meets strict standards for surface quality and dimensional tolerances. We deliver high-quality mold steel plates through meticulous milling and finishing processes, laying a solid foundation for subsequent mold manufacturing.

With over 20 years of specialized experience, Aobosteel is your expert manufacturing partner in Huangshi, China, not a trading company. We are a dedicated factory specializing in forging high-quality cold-work and hot-work tool steels, including D2 (1.2379), H13 (1.2344), and D3 (1.2080). We offer advanced processes, including ESR, LF, and VD. We are the trusted B2B partner for industrial distributors and manufacturers worldwide—in India, Brazil, Eastern Europe, Vietnam, and the Philippines—who rely on us for custom-produced forged or hot-rolled materials in round, flat, or square bar formats. Our clients choose us for our competitive factory pricing and our commitment to quality; every order is delivered in an annealed state (<255HB), 100% UT tested, and accompanied by a full Material Test Certificate (MTC).

While this page is specifically for D2, we offer a comprehensive range of hot-work and cold-work tool steels. Please specify your requirements (Size, Quantity, Grade) and we’ll send you a quote.
