Low temperature tempering (150-250 degrees) The microstructure obtained by low temperature tempering is tempered martensite. The purpose is to reduce the quenching stress and brittleness of the quenched steel on the premise of maintaining high hardness and high wear resistance, so as to avoid cracking or premature damage during use. It is mainly used for a variety of high carbon cutting tools, measuring tools, API5L,GB\/T9711.1 pipeline steel pipe, rolling bearing and carburizing parts, temper hardness is generally HRC58-64. 2. \u00a0Moderate tempering (250-500 degrees) The microstructure obtained by [&hellip;]","thumbnail_url":"https:\/\/www.wldsteel.com\/wp-content\/uploads\/2023\/02\/1675391791003.png"}
