In the precision tooling and plastic mould industry, material quality directly affects mould performance, durability, and surface finish. Choosing a trusted ESR grade steel supplier in Gurugram is essential for manufacturers seeking improved material purity, superior machinability, and long-term mould reliability.
What Is ESR Grade Steel?
ESR (Electro Slag Remelting) steel is a premium-quality steel produced through a secondary refining process that improves:
- Material purity
- Structural uniformity
- Mechanical performance
- Surface finish quality
During the ESR process, the steel is remelted under a controlled slag layer, which removes:
- Non-metallic inclusions
- Impurities
- Segregation defects
👉 The result is cleaner and more reliable steel for precision mould applications.
Why ESR Grade Steel Is Preferred for Mould Applications
✔ Improved Material Purity
ESR steel offers:
- Lower inclusion content
- Better microstructure uniformity
- Enhanced cleanliness
This improves mould performance and reduces the risk of surface defects.
✔ Superior Polishability
One of the biggest advantages of ESR steel is its excellent polishing capability.
Benefits include:
- Mirror-finish mould surfaces
- Better cosmetic appearance of plastic products
- Improved optical clarity in transparent moulded components
👉 Ideal for:
- Automotive parts
- Medical moulds
- Optical plastic products
✔ Better Corrosion Resistance
ESR grade mould steels provide:
- Improved resistance to rust and pitting
- Longer mould life in humid or corrosive environments
This is especially important when moulding:
- PVC materials
- Flame-retardant plastics
- Chemically aggressive polymers
✔ High Dimensional Stability
The refined internal structure of ESR steel ensures:
- Uniform hardness
- Reduced internal stress
- Better machining accuracy
👉 Essential for precision tooling and high-tolerance moulds.
Common ESR Grade Steels Used in Mould Manufacturing
Popular ESR mould steel grades include:
- 1.2316 ESR
- P20 ESR
- H13 ESR
