Abstract
DC60(19/09/54) แผ่นเหล็กกล้ารีดร้อนทนแรงดึงสูงที่มีทั้งความต้านทานแรงดึงกับความสามารถใช้งานได้ดี (การยืดตัวเป็นหน้าแปลน)เป็นแผ่นเหล็กกล้ารีดร้อนทนแรงดึงสูงซึ่งมีองค์ประกอบจากC:0.005% ขึ้นไปและไม่เกิน0.050%,Si:ไม่เกิน0.2%,Mn:ไม่เกิน0.8%,P:ไม่เกิน0.25%,S:ไม่เกิน 0.01%,N:ไม่เกิน0.01%,Ai:ไม่เกิน0.06%,Ti:0.05%ขึ้นไปและไม่เกิน0.10%โดย%มวลซึ่ง เป็นไปตามTiมากกว่าหรือเท่ากับ0.04+(N/14x48+S/32x48)และส่วนที่เหลือเป็นFeกับสิ่งแปลกปลอมที่ไม่สามารถ หลีกเลี่ยงได้กับเมตริกซ์ซึ่งมีสัดส่วนพื้นที่เป็น95%ขึ้นไปต่อโครงสร้างของเฟสทั้งหมดและคาร์ไบด์ที่มี ขนาดเล็กมากซึ่งมีเส้นผ่าศูนย์กลางเฉลี่ยน้อยกว่า10nmซึ่งมีTiตกตะกอนกระจายมีโครงสร้างซึ่งมี สัดส่วนปริมาตร0.0007ขึ้นไปต่อโครงสร้างทั้งหมดของคาร์ไบด์ที่มีขนาดเล็กมากดังกล่าวและมีความ ต้านทานแรงดึง590MPaขึ้นไปกับความสามารถใช้งานได้ดี รูปที่เลือกไม่มี DC60(19/09/54) High tensile hot rolled steel plate with both good tensile strength and workability. (Flange Elongation) is a high tensile hot rolled steel plate with a composition of C: 0.005% or more and not more than 0.050%, Si: not more than 0.2%, Mn: not more than 0.8%, P: not. Exceeds 0.25%,S:not exceeds 0.01%, N: not more than 0.01%, Ai: not more than 0.06%, Ti: 0.05% or more and not more than 0.10% by % mass of which According to Ti greater than or equal to 0.04+(N/14x48+S/32x48) and the rest is Fe with foreign matter that cannot This can be avoided with a matrix having an area ratio of 95% or more to the total phase structure and with carbides containing very small, whose average diameter is less than 10nm, which has Ti precipitated dispersed structure, which has Volume ratio of 0.0007 or more to the entire structure of such very small carbides and Resists tensile strength of 590MPa and above with good usability. The selected picture does not exist.
