What Is 1.2085 Plastic Mould Steel And How To Use It

1.2085 is a type of plastic mold steel, also known as AISI 420 Steel. It is a martensitic stainless steel with high carbon and chromium content, making it well-suited for applications in the plastic molding industry. Here are some key characteristics and information about 1.2085 Plastic Mould Steel:



Key Features:

Composition: It typically contains around 0.55-0.64% carbon, 13-14% chromium, and smaller amounts of other alloying elements like manganese and silicon.

Hardness: 1.2085 Steel can be hardened to a high level, providing excellent wear resistance and durability.

Corrosion Resistance: As a stainless steel, it offers good corrosion resistance.

Polishing Properties: 1.2085 has good polishing properties, making it suitable for applications where a smooth surface finish is required.

Applications:

Plastic Molds: Due to its high hardness, good wear resistance, and corrosion resistance, 1.2085 is commonly used in the manufacturing of Plastic Injection Molds and extrusion dies.

Tooling: It can be used for various tooling applications where resistance to wear and corrosion is important.

Heat Treatment:

1.2085 Plastic Mold Steel typically undergoes heat treatment processes to achieve the desired hardness and mechanical properties. The heat treatment process may involve quenching and tempering to enhance hardness while maintaining toughness.

Machining and Fabrication:

1.2085 Steel is machinable, but due to its high hardness, machining should be performed with the appropriate tools and techniques. Post-machining heat treatment might be necessary.

Care and Maintenance:

Proper care and maintenance, including regular cleaning and corrosion prevention measures, can extend the life of molds and tools made from 1.2085 steel.

When using any specific type of steel for a particular application, it's essential to consult with the steel supplier or metallurgist to ensure proper handling, heat treatment, and maintenance practices are followed. The choice of steel for a given application depends on the specific requirements of the manufacturing process and the desired properties of the end product.
