DIN 1.2083 ESR Steel: Properties, Applications, and Benefits.

DIN 1.2083 ESR is a highly popular and versatile stainless steel grade, primarily used in industries that demand high corrosion resistance, superior polishability, and excellent wear resistance.

Known for its exceptional quality and reliability, this steel is produced through the Electro-Slag Remelting (ESR) process, which further enhances its material properties by minimizing inclusions and ensuring a more uniform composition.

In this article, we’ll discuss the properties, applications, and benefits of DIN 1.2083 ESR steel, highlighting why it’s a top choice for various high-performance applications.

What is DIN 1.2083 ESR Steel?

DIN 1.2083 ESR, also known as X40Cr14 ESR, is a martensitic stainless steel containing approximately 0.4% carbon and 13% chromium.

The ESR process significantly improves the cleanliness and homogeneity of this steel, making it ideal for demanding applications where the material’s durability and resilience are critical.

This grade is particularly valued for its excellent corrosion resistance, which makes it suitable for use in environments exposed to moisture, chemicals, and other corrosive elements.

Additionally, the high chromium content provides the necessary hardness and wear resistance, while the ESR process enhances its machinability, making DIN 1.2083 ESR steel a preferred material in toolmaking and other precision-demanding industries.

Key Properties of DIN 1.2083 ESR Steel.

DIN 1.2083 ESR steel offers a range of advantageous properties that make it suitable for demanding applications. Here’s an overview of its key characteristics:

1. High Corrosion Resistance:-

The high chromium content in DIN 1.2083 ESR steel provides excellent resistance to corrosion, even in environments where the steel is exposed to water, acids, or other potentially corrosive substances.

This property makes it ideal for applications requiring longevity and stability in moist or chemically aggressive conditions.

2. Enhanced Hardness and Wear Resistance:-

Due to its martensitic structure and ESR processing, DIN 1.2083 ESR achieves high hardness levels (typically 50-52 HRC when hardened and tempered).

This hardness translates to superior wear resistance, which is essential in applications where the material is subjected to friction or abrasive forces, such as molds and dies.

3. Improved Machinability.

The ESR process reduces impurities and refines the steel’s microstructure, making DIN 1.2083 ESR easier to machine compared to other grades.

This property benefits industries that require high-precision tooling and makes the steel cost-effective by reducing machining time and tool wear.

4. Excellent Polishability.

Another valuable property of DIN 1.2083 ESR steel is its outstanding polishability, making it suitable for applications where a high-gloss surface is required, such as plastic molding.

This characteristic is essential for molds used in producing optical components or other products where a smooth surface finish is critical.

5. Good Toughness
DIN 1.2083 ESR also offers good toughness and impact resistance, despite its hardness. This balance between hardness and toughness makes it ideal for tooling applications where strength is required without compromising on resistance to cracking or chipping under stress.

Chemical Composition of DIN 1.2083 ESR Steel

The approximate chemical composition of DIN 1.2083 ESR is as follows:-

• Carbon (C): 0.36 – 0.42%
• Chromium (Cr): 12.5 – 14.5%
• Silicon (Si): ≤ 1.0%
• Manganese (Mn): ≤ 1.0%
• Phosphorus (P): ≤ 0.03%
• Sulfur (S): ≤ 0.03%

This composition is optimized to provide a balance of corrosion resistance, hardness, and polishability, making DIN 1.2083 ESR versatile and durable for many demanding applications.
