Abstract
DC60(27/04/54) แผ่นเหล็กกล้ารีดร้อนไร้สนิมจำพวกเฟอร์ไรต์ที่มีความเหนียวดีซึ่งมีค่าแรงกระแทกของชาฟิที่ 50องศาเซลเซียสเป็น100J/ตารางเซนติเมตรขึ้นไปและมีความทนทานการกัดกร่อนสูงกล่าวอย่างเป็นรูปธรรม คือมีC:ไม่เกิน0.020%,Si:ไม่เกิน1.0%,Mn:ไม่เกิน1.0%,P:ไม่เกิน0.06%,S:ไม่เกิน 0.01%,Cr:18.0ถึง24.0%,Mo:ไม่เกิน0.3%,Nb:0.15ถึง0.40%,Ti:ไม่เกิน0.015%,N:ไม่ เกิน0.020%,AI:0.20ถึง0.40%โดย%มวลและเป็นเงื่อนไขตามสูตร(A)กับ(B)ส่วนที่เหลือเป็น Feกับวัตถุไม่บริสุทธิ์ที่ไม่สามารถหลีกเลี่ยงได้ Ti*Nน้อยกว่าหรือเท่ากับ8.0*10ยกกำลัง5...(A) 10*(C+N)น้อยกว่าหรือเท่ากับNbน้อยกว่าหรือเท่ากับ0.25*(C/12+N/14)*93...(B) อนึ่งแต่ละสัญลักษณ์ธาตุแสดงปริมาณที่มีส่วนประกอบในเหล็กกล้า(%โดยมวล) DC60(27/04/54) Hot-rolled ferrite stainless steel sheet with good toughness and Shafi impact strength. 50 degrees Celsius is 100J/square centimeter or more and has high corrosion resistance, in concrete terms. That is, there is C: not more than 0.020%, Si: not more than 1.0%, Mn: not more than 1.0%, P: not more than 0.06%, S: not more than 0.01%,Cr:18.0 to 24.0%,Mo:not more than 0.3%,Nb:0.15 to 0.40%,Ti:not more than 0.015%,N:No exceeds 0.020%, AI: 0.20 to 0.40% by % mass and is conditional according to formula (A) and (B), the rest is Fe and impurities that cannot be avoided Ti*N less than or equal to 8.0*10 to the power of 5...(A) 10*(C+N) less than or equal to Nb less than or equal to 0.25*(C/12+N/14)*93.. .(B) Furthermore, each element symbol indicates the amount contained in steel (% by mass).
