Polish 1.2312 Plastic Mould Steel Round Bars are alloy tool steel bars supplied by Dongguan Songshun Mould Steel Co., Ltd. in China. The material is designated 1.2312 (40CrMnNiMo8-6-4 / P20+Ni), a chromium‑manganese‑molybdenum‑nickel alloy. Bars are offered in annealed or quenched‑and‑tempered (Q+T) condition with surface finishes that include black, peeled, machined, milled or turned. Delivery is either hot rolled or forged round bars as specified by the buyer.
The alloy provides good machinability and a polished finish suitable for large‑section tooling. Typical industry practice uses diameters from 6 mm up to 200 mm with a hardness range of 28‑32 HRC after Q+T treatment. Standard tolerance is ±0.02 mm for diameters up to 50 mm and ±0.05 mm for larger sizes. The bars meet 100 % ultrasonic testing and carry ISO and SGS mill certificates.
These bars are commonly used for plastic injection moulds, blow moulds, die‑casting tooling and wear strips in automotive, consumer‑goods and packaging sectors. Importers should confirm the required heat‑treatment, surface finish and dimensional tolerance before placing an order. Trade terms such as MOQ, lead time and Incoterms are not disclosed in the listing and should be verified with the supplier.

Before confirming an order, verify the alloy grade, heat‑treatment state and surface finish against your mould design requirements. Request the mill certificate and ultrasonic test report to ensure the material meets the specified 1.2312 standards. Confirm the dimensional tolerance and diameter range to avoid machining re‑work.
Discuss the preferred Incoterm - FOB, CIF or DDP - with Dongguan Songshun Mould Steel Co., Ltd. and ask for an estimated lead time based on the requested quantity and delivery condition. Payment terms are not listed, so negotiate a suitable arrangement such as T/T or L/C after reviewing the supplier’s credit profile. Verify the port of loading in China to align with your freight forwarder’s schedule.
Arrange a third‑party inspection at the factory or at the loading port to validate the ultrasonic test results and surface condition. Ensure that the inspection agency can provide a detailed report covering hardness, dimensions and any visual defects. Retain all certificates and inspection documents for customs clearance and downstream quality assurance.
