Plastic 1.2312 mould steel flat bar from Dongguan Songshun Mould Steel Co., Ltd is a pre-hardened chromium-molybdenum alloy steel supplied in plate or flat bar form, meeting AISI, ASTM, DIN, GB and JIS standards. The material is delivered in the annealed or Q+T condition with a hardness of 28 to 32 HRC, making it ready for machining without further heat treatment. Available in diameters up to 800 mm, it is offered in black, peeled, machined or ground surface finishes to suit different tooling requirements.
As a Cr-Mo alloy steel, 1.2312 offers good machinability and polishability, which are critical for producing high-precision plastic injection moulds, blow moulds and die-casting dies. Typical industry use includes applications where dimensional stability and uniform hardness are required across large cross-sections. The steel’s composition typically includes 0.35 to 0.45 percent carbon, 1.8 to 2.2 percent chromium and 0.3 to 0.5 percent molybdenum, providing a balance of toughness and wear resistance.
This steel is widely adopted by manufacturers producing high-volume plastic components for automotive, electronics and consumer goods industries. The supplier provides mill test certificates and supports 100 percent UT testing, with packaging optimized for sea freight in 20ft or 40ft containers. Standard lead time is 15 days after payment, with delivery conditions including peeled or black surfaces. Buyers sourcing for large-scale production should confirm dimensional tolerances and surface finish requirements before ordering.

Before placing an order, verify the exact dimensional tolerances and surface finish requirements for your application. Confirm that the supplied hardness of 28 to 32 HRC meets your machining and tooling needs, as this pre-hardened condition may not be suitable for all use cases. Request mill test certificates and UT test reports to ensure the material’s quality and consistency.
Discuss logistics and Incoterms with the supplier, as these will impact costs and delivery timelines. The standard lead time is 15 days after payment, but this may vary for larger or custom orders. Clarify whether the quoted price includes sea freight or if it is FOB, CFR or CIF, and confirm packaging specifications for containerized shipment.
Conduct quality checks upon receipt, focusing on surface finish, dimensional accuracy and hardness. For critical applications, arrange third-party inspection or testing to validate the material’s properties. Ensure all documentation, including mill certificates and SGS reports, is provided and matches the ordered specifications.
