Mold Steel Plates & Shafts – DC-53, SKD-61 & Oil-Harden

Zhejiang Ruihexuan Import and Export Co., Ltd. supplies mold steel plates and shafts in DC-53, SKD-61, and Oil-Harden grades for cold work, hot work, plastic mold, and general tooling applications. Different steel grades are available for applications requiring wear resistance, toughness, thermal fatigue resistance, dimensional stability, and reliable machining performance.

Choose the Right Steel Grade for Your Tooling Application

Tooling performance depends heavily on selecting a steel grade that matches the working conditions. Cutting and stamping tools may require high wear resistance and toughness, while die casting and hot forging applications place greater demands on high-temperature strength and resistance to thermal fatigue.

DC-53 for Cold Work Tooling

DC-53 is a cold work die steel developed for applications requiring a combination of hardness, toughness, and wear resistance. After appropriate heat treatment and tempering, it can achieve a hardness of approximately 62–63 HRC. Its toughness and resistance to cracking after wire EDM make it suitable for demanding precision tooling applications.

Typical applications include precision stamping dies, cold forging dies, punches, forming dies, and other cold work tools where resistance to wear and cracking is important.

SKD-61 for Hot Work Applications

SKD-61 is a hot work die steel known for its high-temperature strength, toughness, and thermal fatigue resistance. These properties make it suitable for tooling exposed to repeated heating and cooling cycles during production.

Common applications include aluminum and zinc die casting dies, hot forging dies, extrusion tooling, and hot shear blades. Proper heat treatment can help the material maintain the mechanical properties required for repeated high-temperature service.

Oil-Harden Steel for General Tooling

Oil-Harden steel is a general-purpose oil-hardening tool steel designed for applications where good hardness, machinability, and dimensional stability are required. Its relatively small dimensional change during oil quenching can be beneficial for tooling where maintaining dimensional accuracy after heat treatment is important.

It can be used for blanking dies, forming dies, cutting tools, jigs, fixtures, and other general-purpose tooling components.

Plate and Shaft Supply Options

Zhejiang Ruihexuan provides different product forms according to the requirements of the application. DC-53 is available in both plate and shaft forms, while SKD-61 and Oil-Harden are supplied as steel plates.

Available dimensions can be customized according to the buyer's requirements, including different plate thicknesses and shaft diameters. Buyers can provide drawings, dimensions, material requirements, or application details for specification confirmation before ordering.

Material Features That Matter in Production

The supplied mold and tool steels are selected for applications where material consistency and predictable processing are important. Key characteristics include stable hardness and microstructure after appropriate heat treatment, good machinability, suitable polishability, and resistance to wear during repeated tooling operations.

Different sizes and specifications are available to accommodate machining requirements and reduce unnecessary material removal during tool manufacturing. For customized orders, dimensions, tolerances, surface condition, and required material documentation can be confirmed before production.

Applications Across Different Tooling Processes

These steel grades can be used across a range of industrial tooling applications. DC-53 is mainly suited to cold work tooling, while SKD-61 is commonly selected for hot work environments. Oil-Harden provides a practical option for general-purpose dies and tools.

Typical applications include plastic molds, die casting dies, stamping dies, cold forging dies, hot forging dies, blanking dies, forming dies, cutting tools, punches, and precision tooling components.

Quality Control from Material to Shipment

Zhejiang Ruihexuan has supplied metal materials since 2015. Its Guangdong production facility operates under an ISO 9001 quality management system, supporting standardized quality control throughout production and order fulfillment.

Before shipment, each batch can undergo dimensional inspection and hardness verification to help ensure that the supplied material meets the confirmed specifications. Inspection requirements can also be discussed according to the application and buyer's quality standards.

Material Documentation and Order Verification

For buyers who require traceable material information, material certificates can be provided with each batch. Real material samples can also be arranged when sample confirmation is required before a larger order.

Buyers can verify key specifications such as steel grade, dimensions, hardness requirements, and material documentation before shipment. Loading photos and relevant shipping documents can also be shared for order verification and logistics coordination.

Custom Sizes and Steel Grades

Tooling projects often require specific dimensions rather than standard stock sizes. Zhejiang Ruihexuan can discuss custom sizes and material requirements based on the buyer's drawings or specifications.

When requesting a quotation, buyers are encouraged to provide the required steel grade, plate thickness or shaft diameter, length, quantity, heat treatment requirements, surface condition, and any required inspection or certification documents. This information helps confirm the appropriate material and provide a more accurate quotation.

Request a Sample or Quotation

Whether you are sourcing steel for stamping dies, die casting tooling, forging applications, plastic molds, or general precision tools, selecting the appropriate grade and specification is an important part of controlling tooling performance and production costs.

Contact Zhejiang Ruihexuan to discuss your required steel grade, dimensions, quantity, and application. Samples and material documentation can be arranged according to project requirements.
