Chung Metals Located in Da Nang, Vietnam, offers to manufacture and supply high quality metal products such as Tool and Die Steel with specialties in Tool and Die Steel D2 Bars which stands out for high hardness, abrasion resistance and dimension stability. They can be suitable to be applied on tooling parts, mainly used in making of dies and punches, to give precision accuracy where durability is one of the necessary requirements of use. Chung Metals has made sure that D2 bars are in many sizes and suited to various industries’ specific requirements, bringing with them outstanding reliability and quality for their customers.
D2 tool and die steel bar is a high-carbon, high-chromium steel known for its excellent resistance to wear, hardness, and toughness. It generally contains about 1.50% carbon, 12.00% chromium, 0.90% molybdenum, and 0.80% vanadium along with trace amounts of manganese, silicon, and phosphorus. Upon heat treatment, D2 steel reaches a hardness of around 58-62 HRC, which makes it very suitable for applications with high wear-resistance requirements, e.g., punches and dies and shear blades. Some other mechanical properties include high tensile strength, good machinability, and resistant to abrasive wear albeit at greater risk of fracturing owing to the brittleness.

Tool and Die Steel D2 Bars can be welded, but it's challenging due to their high carbon content. Preheating, post-weld heat treatment, and using specific filler materials are essential.
Tool and Die Steel D2 Bars are semi-corrosion-resistant due to high chromium content (12%). While not fully stainless, they offer moderate resistance to rust in less aggressive environments.
D2 tool and die steel bars are extensively used in the manufacturing industries, where high wear resistance and durability are necessary. Typical applications include cutting tools, dies, molds, punches, shear blades, and stamping tools. Because of its high hardness and resistance to abrasion, it is used as a forming and shaping agent for metals, plastics, and other materials. D2 is also employed in cold working tools such as blanking dies, threading tools, and deep drawing die presses, where high precision and durability are required. While D2 is still popular among manufacturers in automotive, aerospace, and metalworking industries for tools that are subject to high wear, it is rather brittle when subjected to impact.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
