The invention provides a material of throttle valve rod and manufacturing technology, and relates to throttle valve rod manufacturing technology. The material of throttle valve rod is the throttle valve rod provided with an integral structure and manufactured by machining of stainless steel, and brass powder is adopted to carry out thermal spraying on the surface of the end heads of the throttle valve rod. The manufacturing technology comprises the steps that material preparation is carried out, thermal treatment is carried out, machining is carried out, the thermal spraying is carried out, finish machining is carried out and flaw detection is carried out. The throttle valve rod with the integral structure is manufactured by adopting the stainless steel material to replace original alloy steel materials, the technology is rigorous, the end heads of the throttle valve rod without micro-crack can be realized, erosion resistance and abrasion resistance of products are improved, and the quality and yield of the products are guaranteed.
