Mechanical Properties for Major Parts in Agricultural Machinery (II) - Comparison for Suitability in Chemical Ingredient -

농업기계 주요부품의 기계적 성질에 관한 연구 (II) - 화학성분의 적합여부에 따른 비교 -

This study was carried out to investigate mechanical properties o major part for agricultural machinery in Korea. The results are as follows ; 1. The mechanical Properties for heat resisting steel bars, alumium alloy castings, carbon steel for machine structural use, chromium molybdenum steels, high strength brass castings and carbon tool steels are proper for Korean standard. 2. The mechanical properties fir spring steels used to mould board, share of plow and blade of rotary are not suitable to Korean standard. Ⅰ think that a counterplan for quality rising is necessary such as supply of good quality materials and improvement of new materials in Korean agricultural machinery.
