Aobo Steel supply SKD6 steel for your project
Premium SKD6 Tool Steel Supplier for Unmatched Durability
SKD6 tool steel is a high-quality alloy used primarily to manufacture molds and dies. Known for its superior toughness, wear resistance, and ability to withstand high-temperature environments, SKD6 is widely used in industries such as automotive, aerospace, and heavy machinery. This steel grade’s performance in demanding applications has made it a popular choice for tools that require durability and precision.
Most cost-effective, high-quality supplier of D2 steel
We offer both D2 electric furnace steel and D2 ESR steel. Considering our customers’ purchasing costs, we produce D2 round bars with diameters under 200mm using the electric furnace method, which can meet Ultrasonic testing (UT) Sep 1921-84 D/d flaw detection. Customers can purchase high-standard D2 round bars at a lower cost. We adopt the ESR process for diameters above 200mm to ensure that the internal structure can meet Ultrasonic testing (UT) Sep 1921-84 E/e flaw detection.
Excellent D2 Forged Steel Supplier
Aobo Steel has over 20 years of experience in forging D2 steel, giving us a deep practical understanding of quality control in this field. Our D2 forged steel products mainly come in round bar, plate, and block shapes. We have over 40 suppliers providing the best processing services, enabling us to offer advantages such as short lead times, stable quality, and competitive prices.
