Abstract

การประดิษฐ์ปัจจุบันจัดให้มีแผ่นเหล็กกล้ารีดเย็นแข็งแรงสูง (hight-strength cold-rolled steel sheet) ซึ่งมีความแข็งแรง ณ จุดคราก (yield sterngth - YP) สูงที่ 400 เมกะปาสกาลหรือ มากกว่านั้น, แอนไอโซทรอปีเชิงระนาบของความยืด (planer anisotropy of elongation) ที่ต่ำ, และ สภาพอัดขึ้นรูปได้ (press formability) ที่ดีมาก ซึ่งสามารถนำมาใช้ผลิตชิ้นส่วนยานยนต์และ อุปกรณ์ไฟฟ้าได้อย่างเหมาะสม และวิธีการผลิตแผ่นเหล็กกล้ารีดเย็นแข็งแรงสูงนี้ แผ่นเหล็กกล้าแข็งแรงสูงที่มีแอนไอโซทรอปีเชิงระนาบของความยืดที่ต่ำนี้ประกอบด้วย (ในหน่วยเปอร์เซนต์โดยมวล) C The current invention provides high strength cold rolled steel sheets. (hight-strength cold-rolled steel sheet) which has a high yield sterngth (YP) of 400 MPa or more, planer anisotropy of elongation ) Low, and very good press formability, which can be used to manufacture automotive parts and Properly electrical equipment And this high strength cold rolled steel sheet production method A high-strength steel plate with a plane anisotropy of this low elongation consists of (In percent by mass) C
