Abstract
DC60 (10/07/57) การประดิษฐ์นี้ได้ให้เหล็กกล้าชนิดหนึ่งสำหรับการผลิตสลักเกลียวที่มีความเเข็งเเรงสูงเเละ ยังคงมีความต้านทานการเปราะเนื่องจากไฮโดรเจน (hydrogen embrittlement resistance) ที่ดีเยี่ยม เหล็กกล้านี้ประกอบด้วย C 0.30% ถึง 0.50%, Si 1.0% ถึง 2.5%, Mn 0.1% ถึง 1.5%, P มากกว่า 0% ถึง 0.015%, S มากกว่า 0% ถึง 0.015%, Cr 0.15% ถึง 2.4%, Al 0.010% ถึง 0.10%, N 0.001% ถึง 0.10%, Cu 0.1 % ถึง 0.50%, Ni 0.1% ถึง 1.0%, Ti 0.05% ถึง 0.2% และ V 0% ถึง 0.2% โดยส่วนที่ เหลือจะประกอบด้วยเหล็กและสารเจือปนที่ไม่สามารถหลีกเลี่ยงได้ โดยที่ อัตราส่วน [Ni]/[Cu] มีค่า เท่ากับ 0.5 หรือมากกว่า และปริมาณรวม [Ti]+[V] มีค่าเท่ากับ 0.085% ถึง 0.30% DC60 (10/07/57) This invention provides a type of steel for the production of high strength and high strength bolts. It retains excellent hydrogen embrittlement resistance (hydrogen embrittlement resistance) .This steel is composed of C 0.30% to 0.50%, Si 1.0% to 2.5%, Mn 0.1% to 1.5%, P greater than 0% to 0.015%, S. Over 0% to 0.015%, Cr 0.15% to 2.4%, Al 0.010% to 0.10%, N 0.001% to 0.10%, Cu 0.1% to 0.50%, Ni 0.1% to 1.0%, Ti 0.05% to 0.2%, and V. 0% to 0.2%, with the rest being composed of iron and unavoidable additives where the ratio [Ni] / [Cu] is 0.5 or more and the total content [Ti] + [V] is equal. 0.085% to 0.30%
