420 Plastic Mould Steel Round Bars
420 Plastic Mould Steel Round Bars from Dongguan Songshun Mould Steel Co., Ltd. are martensitic stainless steel bars produced to AISI 420 or DIN 40Cr13 grade, with a chromium content of 12 to 14% and carbon ranging from 0.15 to 0.40%. These round bars are supplied in diameters from 20mm to 600mm and lengths from 1000mm to 6000mm, making them suitable for precision tooling applications where hardness and corrosion resistance are critical. The material’s composition ensures high wear resistance, which is essential for plastic injection moulding tools that operate under repeated stress cycles.
As a martensitic grade, 420 Plastic Mould Steel Round Bars can be heat treated to achieve high hardness levels, typically up to 50-55 HRC after quenching and tempering. This makes them ideal for moulds that require both strength and the ability to hold fine details without deformation. The steel’s machinability in the annealed state allows for complex shaping, while its corrosion resistance in mild environments reduces maintenance needs for tools exposed to moisture or chemical agents. Standard industry variants for this grade often include polished or ground finishes to meet surface requirements for mould cavities.
These bars are primarily sourced by tool and die makers, mould manufacturers, and precision engineering workshops in the automotive, consumer goods, and industrial equipment sectors. Buyers typically order in bulk to meet production demands for high-volume moulding operations. The bars are shipped as raw material for further machining, with packaging and handling tailored to prevent surface damage during transit. Confirm with the supplier for exact lead times, as these depend on diameter, length, and finish specifications.

These 420 Plastic Mould Steel Round Bars are manufactured to AISI 420 / DIN 40Cr13 grade specifications, offering excellent hardness and corrosion resistance ideal for plastic injection moulding applications. Available in diameters from 20mm to 600mm, these round bars serve tool and die makers, mould manufacturers, and precision engineering workshops worldwide. As a versatile martensitic stainless steel, they are in high demand among B2B buyers sourcing for automotive, consumer goods, and industrial equipment manufacturing sectors, making them a strong candidate for import-export trade.

Sourcing 420 Plastic Mould Steel Round Bars from Dongguan Songshun Mould Steel Co., Ltd. - China Import Guide
Before ordering 420 Plastic Mould Steel Round Bars from Dongguan Songshun Mould Steel Co., Ltd., verify the exact chemical composition and mechanical properties to ensure they meet your tooling requirements. Request a mill test certificate to confirm the chromium and carbon content, as well as hardness levels after heat treatment. This documentation is critical for quality assurance, especially for applications demanding high precision and durability.
Confirm logistics details such as packaging, handling, and shipping methods to prevent surface damage during transit. Discuss Incoterms like FOB or CIF and payment terms to align with your procurement policies. Lead times may vary based on the diameter and length, so clarify these upfront to avoid delays in production schedules. Buyers should also inquire about the supplier’s ability to provide custom finishes or additional processing if needed.
For quality checks, inspect the bars for surface defects, dimensional accuracy, and hardness consistency upon delivery. Use standard industry methods such as ultrasonic testing for internal flaws and hardness testers for verifying HRC levels. Request documentation for heat treatment processes and third-party inspections if applicable. These steps ensure the material meets the specifications required for your moulding or tooling applications.
