Journal: Wide and Heavy Plate
Keyword: S355JR ﹢ N - Z35; Heavy plate; Composition design; Process design;
Abstract: Assisted by the design of composition and various processes such as composite slab manufacture,roll-ing and heat treatment,Jigang successfully develops 185 mm thickness S355JR ﹢ N - Z35 structural steel plate by u-sing various technological methods such as Nb,V,Ti microalloying,high temperature low speed heavy draft rolling,as- rolled plate stack cooling and normalizing. With a redundancy of yield strength and tensile strength over 40 MPa and 50 MPa respectively,average impact energy value at 20 ℃ over 200 J,average value of reduction of area ≥45% ,ul-trasonic flaw detection conforming to the stipulation of EN10160 S1 / E1 standard,the steel plate is of excellent mechan-ical properties and high internal quality.
