摘要： A material deterioration evaluation device for evaluating embrittlement of equipment, includes: an operation data obtaining unit that detects and obtains a state of the equipment as operation data; an operation data storage unit that saves the operation data; a temperature evaluation unit that calculates a predetermined evaluation-target site temperature of the equipment based on the operation data; an evaluation-target component material storage unit that stores material data of a material forming the equipment and embrittlement estimation formulas; an embrittlement evaluation unit that calculates an embrittlement quantity of the material forming the equipment based on the evaluation-target site temperature, the material data, and the embrittlement estimation formulas; a risk evaluation unit that calculates a damage risk of the material that forms the equipment based on the embrittlement quantity; and a recommended maintenance time presentation unit that presents a recommended maintenance time of the equipment based on the damage risk.
