研制的奥氏体－贝氏体复相耐磨铸钢衬板具有高硬度和高韧性（ＨＲＣ４０～５８、αｋ≥１５～４５Ｊ／ｃｍ２），可在铸态下使用，不需热处理；一定条件下，使用寿命比高锰钢高１倍。
The developed austenite-bainitic composite wear-resistant steel liner has high hardness and high toughness (HRC40 ~ 58, αk≥15 ~ 45J / cm2), can be used in the cast state, without heat treatment; certain conditions Under the life of high manganese steel than 1 times.
