STRENGTH AT ELEVATED TEMPERATURE OF HOT-WORKING TOOL STEELS OF 5Cr TYPE AND 3Cr-3Mo TYPE
5Cr型和3Cr—3Mo型热作工具钢的高温强度

The strength at elevated temperature is one of the most important proper-ties of hot-working tool steel.The changes of the strength with temperature are obviouslydivided into two stages.This phenomenon is described by a phenomenlogical theory.Theresults s
