Abstract
DC60(20/04/60) แผ่นเหล็กกล้าเคลือบสังกะสีแบบจุ่มร้อนความแข็งแรงสูงที่มีคุณสมบัติทนต่อการเกิดครีบที่ดี เยี่ยมซึ่งมีความสูงของครีบน้อยและวิธีการผลิตดังกล่าวแผ่นเหล็กกล้าเคลือบสังกะสีแบบจุ่มร้อน ความแข็งแรงสูงที่มีคุณสมบัติทนต่อการเกิดครีบที่ดีเยี่ยมซึ่งมีลักษณะจำเพาะคือส่วนประกอบส่วน ผสมมีองค์ประกอบของC:0.04%ขึ้นไปแต่ไม่เกิน0.13%,Si:1.0%ขึ้นไปแต่ไม่เกิน2.3%,Mn: 0.8%ขึ้นไปแต่ไม่เกิน2.0%,P:ไม่เกิน0.05%,S:0.0010%ขึ้นไปแต่ไม่เกิน0.01%,AI:ไม่เกิน 0.1%,N:ไม่เกิน0.008%โดยมวล%,ส่วนที่เหลือประกอบด้วยเหล็กและสิ่งเจือปนที่หลีกเลี่ยงไม่ได้, และโครงสร้างส่วนประกอบมีเฟสเฟอร์ไรต์ร้อยละ75ขึ้นไปและเฟสเบนไนติกเฟอร์ไรต์ร้อยละ1ขึ้นไป และเฟสเพอร์ไลต์ร้อยละ1ขึ้นไปแต่ไม่เกินร้อยละ10โดยสัดส่วนพื้นที่นอกจากนั้นยังมีสัดส่วนพื้นที่ ของเฟสมาร์เทนไซต์น้อยกว่าร้อยละ5รวมทั้งทำให้สัดส่วนพื้นที่มาร์เทนไซต์/(สัดส่วนพื้นที่เบนไน ติกเฟอร์ไรต์+สัดส่วนพื้นที่เพอร์ไลต์)น้อยกว่าหรือเท่ากับ0.5กลายเป็นจริง รูปที่เลือกใช้รูปที่1 DC60(20/04/60) High strength hot dipped galvanized steel sheet with good burr resistance property. which has a small fin height and such a production method, hot-dip galvanized steel sheets High strength with excellent burr resistance properties, which is characterized by a component The mixture contains elements of C: 0.04% or more but not more than 0.13%, Si: 1.0% or more but not more than 2.3%, Mn: 0.8% or more but not more than 2.0%, P: not more than 0.05%, S:0.0010. % or more but not more than 0.01%, AI: not more than 0.1%, N: not more than 0.008% by mass%, the remainder consists of iron and unavoidable impurities, and the component structure has 75% or more percent ferrite phase and 75% percent benzene ferrite phase. 1 and up and phase perlite 1% or more but not more than 10% in proportion to area. In addition, there is also a proportion of area of the martensite phase is less than 5 percent and makes the proportion of martensite area/(proportion of bennai area Tik ferrite + perlite area ratio) less than or equal to 0.5 becomes true. The picture used is picture 1.
