What is DIN 1.2083 ESR Steel?

DIN 1.2083 ESR Steel is a Versatile Stainless Steel grade plastic mould steel. DIN 1.2083 ESR Grade is a martensitic stainless steel, It’s equivalent to AISI 420 steel, STAVAX ESR, X40Cr14, commonly used in various industries due to its excellent properties.

Key Characteristics of 1.2083 ESR Grade Steel:-

  • Good Corrosion Resistance:- Thanks to its chromium content, it offers decent resistance to atmospheric corrosion and some chemical environments.
  • Excellent Polishability:- Achieves a high-quality, mirror-like finish, making it suitable for applications where aesthetics are important.
  • Good Machinability:- In the annealed condition, it can be easily machined, reducing production costs.
  • High Hardenability:- Can be heat-treated to achieve high hardness levels, enhancing its wear resistance.

Typical Applications of the DIN 1.2083 ESR steel:-

  • High Glossy Plastic Molds:- Particularly for chemically aggressive plastics and high-quality glossy finishing molds.
  • Medical and Surgical Instruments:- Benefits from its corrosion resistance and ability to be polished to high standards.
  • Automotive Components:- Employed in various parts, including those requiring good wear resistance and corrosion protection.
 

What is DIN 1.2344 ESR Steel?

DIN 1.2344 ESR steel, also known as AISI H13 ESR steel, is a high-performance hot work tool steel renowned for its exceptional combination of properties. The “ESR” designation signifies that the steel has been produced using the Electro-Slag Remelting (ESR) process, a sophisticated technique that refines the steel’s microstructure, resulting in improved cleanliness, homogeneity, and overall quality.  

Key Properties of DIN 1.2344 ESR Steel:-

  • High Hardness and Wear Resistance: Achieves high hardness levels (typically around 52-56 HRC) after heat treatment, providing excellent resistance to wear and abrasion, even at elevated temperatures.  
  • Good Toughness: Despite its high hardness, it maintains good toughness, reducing the risk of cracking or chipping during use.  
  • Excellent Thermal Fatigue Resistance: Can withstand repeated cycles of heating and cooling without significant degradation in performance.  
  • High-Temperature Strength: Retains its strength at elevated temperatures, making it suitable for hot work applications.  
  • Good Machinability: In the annealed condition, it can be easily machined, reducing production costs.  
  • Excellent Polishability: Achieves a high-quality, mirror-like finish, important for applications where surface quality is critical.

Typical Applications of the DIN 1.2344 ESR Steel:-

  • Hot Work Tools
  • Dies for forging, extrusion, and die casting of metals  
  • Hot shear blades  
  • Hot extrusion dies  
  • Plastic Molds
