What is Grade VR 400 ESR Steel?
Grade VR 400 ESR is a premium electro-slag remelted (ESR) mould steel designed for high-performance plastic injection moulds and industrial tooling applications. It offers superior cleanliness, improved toughness, excellent polishability, and high resistance to wear and cracking.
The ESR process significantly improves steel quality by reducing impurities, enhancing microstructure uniformity, and ensuring better mechanical properties. This makes VR 400 ESR ideal for precision mould manufacturing where surface finish and durability are critical.
It is widely used in high-end plastic components, automotive moulds, medical device moulds, and electronic part manufacturing industries.
Properties of VR 400 ESR Steel
- Excellent hardness and toughness balance
- High polishability for mirror finish moulds
- Superior wear resistance
- Improved corrosion resistance compared to standard grades
- Uniform microstructure due to ESR refining
- Long tool life in production environments
These properties make VR 400 ESR one of the most preferred choices for engineers and mould manufacturers seeking precision and durability.
Applications of Grade VR 400 ESR
VR 400 ESR is widely used in industries requiring high precision moulds and durable tooling solutions:
- Plastic injection moulds
- Automotive interior and exterior parts
- Packaging moulds
- Medical device moulds
- Electronic housing components
- Consumer product manufacturing
- Industrial plastic components

Technical Insight of VR 400 ESR Steel
VR 400 ESR belongs to a high-performance category of tool steels designed specifically for mould manufacturing industries. The ESR refining process ensures that the steel has minimal inclusions, which improves its polishability and reduces the risk of surface defects in moulded products.
Due to its improved hardness distribution, it performs exceptionally well in high-pressure injection moulding applications where repetitive stress and heat cycles are common.
