Abstract
ในโลหะสำหรับการทำให้แข็งของชั้นพื้นผิว ซึ่งถูกปฏิบัติด้วยการคาร์เบอร์ไรซิง (carburizing)ในช่วงอุณหภูมิที่ 800 องศาเซลเซียส ถึง 900 องศาเซลเซียส องค์ประกอบเคมีของ สิ่งนั้นประกอบด้วย โดย % โดยมวล,C0.10%ถึง 0.60%,Si:0.01%ถึง 2.50%,Mn:0.20% ถึง 2.00%,S:0.0001%ถึง 0.10%,Cr:2.00%ถึง 5.00%,Al:0.001%ถึง 0.50%,N:0.0020% ถึง 0.020%,P:0.001%ถึง 0.050%,และ O:0.0001%ถึง 0.0030%;ส่วนที่เหลืออยู่ของสิ่งนั้น ประกอบด้วยFe และสิ่งเจือปนที่ไม่สามารถหลีกเลี่ยงได้;และปริมาณทั้งหมดของ Cr,Si,และ Mn จะอยู่ที่ โดย % โดยมวล,2.0<หรือเท่ากับCr+Si+Mn<หรือเท่ากับ8.0: In metals for hardening of the surface layers. Which was treated by carburizing (carburizing) in the temperature range of 800 ° C to 900 ° C. Chemical composition of That is composed by% by mass, C0.10% to 0.60%, Si: 0.01% to 2.50%, Mn: 0.20% to 2.00%, S: 0.0001% to 0.10%, Cr: 2.00% to 5.00%, Al: 0.001% to 0.50%, N: 0.0020% to 0.020%, P: 0.001% to 0.050%, and O: 0.0001% to 0.0030%; the remainder of it contains Fe and impurities; and the total quantity. Of Cr, Si, and Mn is where% by mass, 2.0 <or equal to Cr + Si + Mn <or equal to 8.0:
