They are engineered to withstand extreme stress, drastically reduce downtime, and extend the service life of your equipment in the most demanding demolition and mining applications.
Key Features
Applications
Why 42CrMo and 40Cr?
Both 42CrMo and 40Cr are industry-respected materials for critical mechanical parts, especially in mining and construction equipment. The key differentiator is the addition of molybdenum in 42CrMo. This element significantly enhances the steel's hardenability, strength at high temperatures, and most importantly, its resistance to fatigue and impact—making it the premier choice for the largest and most powerful breakers.
