Dongguan VIM Steel Co.,Ltd.

The 1.2367 ESR is a premium-grade hot work tool steel manufactured using the Electro-Slag Remelting (ESR) process. This advanced refining technique ensures exceptional steel cleanliness, a highly uniform microstructure, and superior isotropic mechanical properties. Designed to outperform standard H13 or 1.2344 grades, 1.2367 ESR offers an optimized balance of high-temperature strength, excellent thermal stability, and outstanding toughness, making it the definitive choice for the most demanding thermal stress environments.

Our 1.2367 ESR round bars are specifically engineered for high-performance die casting dies, heavy-duty hot forging tools, and extrusion mandrels. Its resistance to thermal checking (heat crazing) and superior through-hardenability allow for extended tool life and reduced maintenance cycles. Whether you are producing complex aluminum alloy castings or high-speed forging components, this high-toughness tool steel provides the reliability and precision required for modern industrial manufacturing.

Key Performance Benefits
Electro-Slag Remelting (ESR) Quality: Minimal non-metallic inclusions and refined grain structure for maximum fatigue resistance.

Excellent Thermal Stability: Retains high hardness and structural integrity even under prolonged exposure to elevated temperatures.

Superior Hot Toughness: High resistance to brittle fracture and thermal shock, preventing premature cracking in hot work applications.

Optimized Wear Resistance: Enhanced alloy composition ensures a longer service life for high-friction forging and extrusion surfaces.

Uniform Machinability: Consistent material properties throughout the round bar cross-section for predictable CNC processing.

High Polishability: The ESR process allows for a mirror-like finish, essential for high-quality plastic molds or precision die casting.
