Applications of DIN 1.2085 Plastic Mould Steel

DIN 1.2085 Plastic Mould Steel is specifically engineered for applications where corrosion resistance and machinability are critical. Its primary applications include:

• Corrosion-Resistant Mould Bases: DIN 1.2085 steel/DIN 1.2085 Plastic Mould Steel is widely used for mould bases in plastic injection moulding, particularly for processing corrosive plastics such as PVC, POM, or PET. The steel’s ability to resist corrosion reduces wear and extends the lifespan of mould bases.
• Die Sets: The steel’s pre-hardened condition and excellent machinability make it suitable for die sets used in plastic moulding and other precision manufacturing processes.
• Core Parts for Moulds: While not typically used for mould inserts due to its specific hardness and surface finish limitations, DIN 1.2085 is ideal for core parts of moulds where corrosion resistance and workability are prioritized.
• Equipment Requiring Corrosion Resistance: This steel is used in components and equipment exposed to corrosive environments, such as cooling channels in moulds or machinery parts in humid or acidic conditions.

The steel’s versatility makes it a go-to material for industries involved in plastic mould making, aluminum die casting, pressure die casting, and automotive component manufacturing.

Its ability to withstand corrosive plastics ensures that moulds maintain their integrity, reducing downtime and maintenance costs.

Suitability for Corrosive Plastics

Corrosive plastics, such as polyvinyl chloride (PVC) and certain acetals, release acidic byproducts during processing, which can degrade standard steel moulds.

DIN 1.2085 steel is one of the best grades for making moulds for such materials due to its high chromium content and special alloying with Sulphur.

These features provide:

• Enhanced Corrosion Resistance: The steel’s martensitic stainless structure and high chromium content (13.0–14.5%) create a protective oxide layer that resists corrosion from acidic plastics and humid environments.
• Reduced Maintenance Costs: Mould tools made from DIN 1.2085 Plastic Mould Steel require less frequent maintenance and protection compared to standard steels, saving manufacturers significant time and expense.
• Longer Mould Lifespan: The corrosion resistance of DIN 1.2085 ensures that mould bases and die sets remain functional for extended periods, even when exposed to aggressive plastic materials.

The expense of protecting and maintaining mould tools is a significant challenge in the plastic moulding industry.

Regular cleaning, polishing, and coating of moulds to prevent corrosion are time-consuming and costly.

By using DIN 1.2085 steel, manufacturers can minimize these efforts, as the steel’s inherent corrosion resistance reduces the need for frequent interventions.

Limitations: Not Suitable for Mould Inserts

While DIN 1.2085 is excellent for mould bases and core parts, it is not suitable for mould inserts.

Mould inserts require higher hardness, superior surface finish, and greater wear resistance to withstand the direct contact and abrasion caused by molten plastics.

DIN 1.2085, being pre-hardened and optimized for corrosion resistance and machinability, may not meet the stringent requirements for insert applications.

For mould inserts, grades like 1.2316 or 1.2083 are often preferred due to their higher hardness and polishability.

Characteristics of DIN 1.2085 Plastic Mould Steel

DIN 1.2085 Plastic Mould Steel is a pre-hardened martensitic stainless chromium steel with unique characteristics that make it ideal for specific mould-making applications.

Its key characteristics include:

• Corrosion Resistance: The high chromium content (13.0–14.5%) provides excellent resistance to corrosion, making it suitable for moulds processing corrosive plastics and operating in humid or acidic environments.
• Pre-Hardened Condition: Supplied in a pre-hardened state (typically 29–33 HRC), DIN 1.2085 eliminates the need for additional heat treatment, reducing production time and costs.
• Good Machinability: The addition of Sulphur (0.03–0.10%) enhances machinability, allowing for easier cutting, milling, and shaping during mould manufacturing.
• Moderate Toughness: The steel offers sufficient toughness for mould bases and core parts, ensuring durability under mechanical stress.
• Special Alloying: Compared to similar chromium grades (e.g., DIN 1.2083), DIN 1.2085 is characterized by special alloying with Sulphur, which improves its workability without compromising corrosion resistance.

Chemical Composition

The chemical composition of DIN 1.2085 steel contributes to its unique properties. The typical composition is as follows:

Element	Percentage (%)
Carbon (C)	0.38–0.45
Chromium (Cr)	13.0–14.5
Manganese (Mn)	0.6–1.0
Sulphur (S)	0.03–0.10
Silicon (Si)	≤1.0
Phosphorus (P)	≤0.03

Comparison with Similar Grades

DIN 1.2085 offers superior corrosion resistance and machinability compared to other chromium-based tool steels. For example:

• DIN 1.2083: While 1.2083 has similar corrosion resistance, it lacks the Sulphur additive, resulting in lower machinability.
• 1.2316: This grade offers higher polishability and is suitable for mould inserts, but it may not match 1.2085’s machinability for mould bases.
• AISI 420FM: A close equivalent to DIN 1.2085, AISI 420FM has similar properties but may vary slightly in Sulphur content.

Main Characteristics and Applications

DIN 1.2085 Plastic Mould Steel is a pre-hardened martensitic stainless chromium steel with the following standout features:

• Excellent Corrosion Resistance: Higher than similar chromium grades due to its optimized alloying, making it ideal for corrosive plastic moulding applications.
• Enhanced Machinability: The Sulphur additive improves workability, allowing for faster and more cost-effective machining processes.
• Pre-Hardened Structure: Delivered in a ready-to-use condition, reducing the need for additional heat treatment and speeding up production timelines.
• Versatility: Suitable for mould bases, core parts, and equipment requiring corrosion resistance and good mechanical properties.

Main Applications:

• Corrosion-Resistant Plastic Moulds: Used for mould bases and core parts in moulds processing corrosive plastics like PVC, POM, and PET.
• Die Sets and Tooling: Employed in die sets for plastic injection moulding and other precision manufacturing processes.
• Equipment in Corrosive Environments: Ideal for components exposed to moisture, acids, or other corrosive agents, such as cooling channels in moulds.
• Industrial Components: Used in industries like automotive, aluminum die casting, and pressure die casting for durable, corrosion-resistant parts.
