Abstract
1.เหล็กกล้าการตีขึ้นรูปเย็น/ไนไตรดิง ซึ่งมีสารผสมทางเคมีซึ่งประกอบรวมด้วย ปริมาณเปอร์เซ็นต์โดยมวลของ C01 ถึง 0.15 เปอร์เซ็นต์ Si:0.35 เปอร์เซ็นต์หรือน้อยกว่า Mn:0.10 ถึง 0.90 เปอร์เซ็นต์,P:0.030 เปอร์เซ็นต์,Al:0.01 ถึง 0.10 เปอร์เซ็นต์ ,N:0.0080 เปอร์เซ็นต์หรือน้อยกว่า เเละ O:0.0030 เปอร์เซ็นต์หรือน้อยกว่า พร้อมด้วยปริมาณที่ทำให้ได้ดุล ของ Fe เเละสารเจือปน เเละนอกจากนั้น Fnl เเสดงโดยสูตร(1)เท่ากับ 160 หรือน้อยกว่า Fn2 เเสดงโดยสูตร(4)เท่ากับ 90 ถึง 170 Fnl=399xC+26xSi+123xMn+30xCr+32xMo+19xV...(1) Fn3=(669.3xlog C-1959.6xlog N-6983.3)x(0.067xMo+0.147xv)...(2) Fn4=140xCr+125xAl+235xV...(3) Fn4=511xC+33xMn+56xCu+15xNi+36xCr+5Mo+134xV...(4) โดยที่เเต่ละสัญลักษณ์ C,Si,Mn.Cr,Mo,V,N,Al,Cu เเละ Ni ในสูตรข้างต้น(1)ถึง(4) เเสดงเเทนปริมาณบรรจุเป็นเปอร์เซ็นต์โดยมวลของธาตุที่เกี่ยวข้อง: 1.Cold forging steel / nitriding Which contains chemical mixtures which include Mass, percentage by mass of C01 to 0.15 percent, Si: 0.35 percent or less, Mn: 0.10 to 0.90 percent, P: 0.030. Percent, Al: 0.01 to 0.10 percent, N: 0.0080 percent or less, and O: 0.0030 percent or less. Along with the amount that makes the balance of Fe and impurity. In addition, Fnl shown by formula (1) is 160 or less than Fn2 shown, formula (4) is 90 to 170 Fnl = 399xC + 26xSi + 123xMn + 30xCr + 32xMo + 19xV ... (1). Fn3 = (669.3xlog C-1959.6xlog N-6983.3) x (0.067xMo + 0.147xv) ... (2) Fn4 = 140xCr + 125xAl + 235xV ... (3) Fn4 = 511xC + 33xMn + 56xCu + 15xNi + 36xCr + 5Mo + 134xV ... (4) where each symbol C, Si, Mn.Cr, Mo, V, N, Al, Cu and Ni in the above formulas (1) to (4) show the percentage content by mass of the associated elements:
