DIPTI METAL INDUSTRIES
Leading YXM4 Stockist, YXM4 Supplier & YXR4 Exporter (SKH55 / 1.3243 Steel) in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized YXM4 Supplier, YXM4 Exporter, and the foremost YXM4 Stockist of Molten Cobalt High Speed Tool Steel in Mumbai, India. YXM4, equivalent to JIS SKH55 and W.-Nr. 1.3243, is a high-performance Molybdenum-Cobalt high-speed steel. By incorporating 5% Cobalt, YXM4 achieves superior red hardness and seizure resistance compared to standard M2 grades. Strategically optimized for a hardness range of 64-66 HRC, it is the primary choice for cold forging dies, drawing dies, and high-duty cutting tools that operate under high thermal and mechanical loads. As a premier YXM4 Distributor, we supply certified Round Bars and precision Forged Blocks to automotive fastener manufacturers and heavy-industrial tool makers across 75+ countries.

As the primary YXM4 Supplier in Mumbai, Dipti Metal Industries addresses the limitations of standard molten HSS in high-pressure environments. The addition of Cobalt in YXM4 (SKH55) significantly enhances the steel's ability to maintain high hardness even at elevated temperatures (red hardness), while simultaneously improving its resistance to seizure (galling) and high-load pressure. This makes YXM4 an essential material for tool designers working with abrasive materials or high-speed cold forging operations.
The YXM4 Technical Advantage
- Exceptional red hardness due to 5% Cobalt alloy
- Superior seizure resistance for drawing applications
