Carbon microalloyed steel
Carbon microalloyed steel — is carbon steel with the addition of 1% alloying elements to increase the order strength. The alloying elements used somewhat different in microalloying than in conventional alloying. These substances are chemically active — zirconium, boron, tungsten, niobium, aluminum, as well as vanadium, titanium, etc.They are introduced by modern technologies — in the flux-cored wire form, with the required filling for microalloying.
