High-nitrogen titanium alloy is a composite high-nitrogen alloy additive, mainly used in the production of microalloyed steel. Through the role of titanium, nitrogen, silicon and other alloying elements in the steel, the strength and toughness of the steel are effectively improved And other mechanical properties, at the same time compared to the use of a single alloy additive product can effectively reduce costs.
In the steel production process, by adding this product, it can replace a single expensive alloy (copper, camel, etc.) or reduce other products under the qualified conditions of the composition and performance of the finished product (including mechanical properties, process performance, welding performance and fatigue performance). The amount of alloy added, thereby reducing production costs.
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.
