The strategic inclusion of eight percent cobalt allows our molybdenum-cobalt HSS to maintain extraordinary red hardness under intense mechanical stress. It can reach a remarkable heat-treated hardness of 68 to 70 HRC, ensuring lasting edge sharpness. This specific metallurgical composition directly prevents premature tool failure during rigorous and prolonged machining cycles. Your heavy-duty cutting operations will directly benefit from extended tool life and significantly fewer production interruptions.
Despite its incredibly high hardness profile, our SKH-59 steel offers an exceptional level of grindability compared to other high-alloy options. This superior structural balance makes it the ultimate material for machining difficult-to-cut superalloys and high-strength metals. Operators can achieve highly precise edge preparations without compromising the underlying structural integrity of the tool. It consistently delivers reliability when exposed to continuous frictional forces and mechanical shocks.
Every batch of our tool steel undergoes rigorous ultrasonic testing according to Sep 1921 Class3 E/e standards to guarantee internal soundness. We utilize advanced production routes, including EAF LF+VD and ESR furnaces, to ensure maximum internal purity. Independent laboratory verifications confirm exact chemical compositions, mechanical properties, and microstructures before any material is approved. This strict four-step quality procedure guarantees that you receive flawless, high-performance steel blocks and bars.
We provide this material in a comprehensive range of dimensions, accommodating flat thicknesses from 2 to 200mm and round diameters up to 200mm. Customers can select from various surface conditions, including black surface, turned, peeled, grinded, or precision finish milled. Delivering an annealed hardness of 255HB, this flexibility ensures that the supplied material aligns perfectly with your immediate fabrication workflows and specialized equipment requirements.
Our material serves as the ideal foundation for manufacturing premium milling cutters, complex broaches, hobs, and robust end mills. These tools frequently encounter intense heat when cutting stainless steel, titanium alloys, and nickel-based superalloys. The excellent thermal stability of our steel ensures consistent cutting performance across these challenging aerospace and automotive materials. Tooling manufacturers depend on this grade to meet tight industrial tolerances.
Extensively utilized for specialized twist drills and taps, this alloy maintains a critically sharp cutting edge even at highly elevated rotational speeds. The excellent wear resistance minimizes friction and heat generation during deep hole drilling tasks. Professional tool producers consistently rely on this specific grade to manufacture long-lasting, reliable drilling instruments for diverse global markets. It prevents edge dulling and maintains hole accuracy over extended runs.
When chipping resistance is an absolute requirement, our high hardness tool steel performs exceptionally well in high-stress cold work applications. It is frequently engineered into heavy-duty punches, cold extrusion dies, and thread rolling dies. The inherent toughness prevents edge micro-chipping, ensuring the continuous mass production of identical metal components. It significantly reduces the frequency of necessary die replacements and costly machine downtime.
The exceptional durability of this high-speed alloy makes it perfectly suited for manufacturing premium band saw blades and metal-cutting circular saws. These industrial cutting tools demand a material that can endure continuous friction and heavy mechanical shock without rapid dulling. Using our highly refined steel directly translates to faster metal cutting speeds, cleaner material separations, and extended blade longevity in heavy fabrication shops.
