400계열 스테인레스 스틸 분말을 사용한 ABS Sensor Ring 개발

Development of the 400 Series Stainless Steel Powder Sensor Ring for Use in an Antilock Brake System

ABS sensor ring has been manufactured by P/M method using 400 series ferrite stainless steel. The results are as following: It is supposedly sufficient to use for control computer due to good experimental results of magnetic characteristics. Compared with sensor ring made by iron, 400 series ferrite stainless steel has shown a good corrosion resistance without an addition surface treatment. Thus the decreasing production process has been obtained. As a result of hardness and tensile test, 400 series ferrite stainless steel shown a good endurance when it is combined to C/V joint, and has a good hardness properties endurable to sand and pebble impact.
