Nestled in the heart of Kinshasa, Sadiki Metals stands as a dedicated partner to Congo’s growing industrial sector, proudly manufacturing and supplying premium High Speed Steel M35 bars. We understand that your tools are the backbone of your productivity, which is why our M35 bars are engineered to deliver exceptional performance and durability. We are committed to providing local industries with reliable, high-quality materials that meet the rigorous demands of modern machining and fabrication, supporting progress right here in our community.
The strength of our M35 bars comes from a sophisticated composition that includes tungsten, molybdenum, cobalt, and vanadium. This specific blend gives the steel its remarkable red-hardness, meaning it retains its cutting edge and strength even when exposed to the high temperatures generated during fast machining operations. You can count on consistent hardness, superior wear resistance, and the toughness needed to handle demanding cuts, ensuring your tools last longer and perform better under stress.

Yes, High-Speed Steel M35 can be welded, but it requires careful control of heat and preheating. Post-weld heat treatment is often necessary to restore its hardness and performance.
Yes, High-Speed Steel M35 bars can be customized in terms of dimensions, shape, and surface finish. Machining and heat treatment processes can also be tailored to meet specific performance requirements.
High-Speed Steel M35 bars should be stored in a dry, cool environment, away from moisture and extreme temperatures. They should be kept on racks to prevent contact with corrosive materials.
These bars are the ideal choice for creating high-performance cutting tools that drive industry forward. They are commonly transformed into drills, end mills, taps, and saw blades that excel in machining tough materials like stainless steel and high-temperature alloys. Whether in automotive manufacturing, aerospace engineering, or general metalworking, tools made from our M35 bars allow for faster production speeds and extended tool life, directly boosting efficiency and reducing downtime on your shop floor.
