High nitrogen composite alloy
High nitrogen composite alloy is a composite high nitrogen alloy additive, mainly used in the production of microalloyed steel. The product can adjust the main components of the product according to the actual steelmaking process needs of customers. Through the role of niobium, vanadium, titanium, nitrogen and other alloy elements in the steel, the mechanical properties such as the strength and toughness of the steel can be improved. Additive products can reduce costs.
In the steel production process, through the addition of high-nitrogen composite alloys, the composition and performance of the finished product (including mechanical properties, process performance, welding performance and fatigue performance, etc.) are guaranteed to replace expensive alloys or reduce the addition of other alloys, thereby reduce manufacturing cost.
This technology has low requirements for the equipment configuration of the steel production line, and is especially suitable for production lines that do not have controlled rolling and cooling conditions. At the same time, it can also avoid poor product appearance (corrosion and bending) caused by strong water penetration and affecting performance. Other organizations.
This technology has broad requirements for steel smelting, continuous casting, and hot rolling processes. There is no need for equipment changes in the application, and basically no need to change the existing production process, which is convenient for industrial testing and large-scale industrial production.
Product Technical Index
N: 6-20%, Nb: 5-30%, Ti: 10-30%, and other auxiliary elements and a small amount of rare earth elements. The indicators are changed according to the actual production process and indicator control conditions of the customer, and the actual conditions prevail.
It is suitable for the production of rebar above the national standard level 3, such as: HRB400, HRB500, etc.
