1. The variety of wire rods can generally be divided into the following categories according to the steel type:
1). Wire rod for flexible wire. The main carbon structural steel Q195, Q215, and Q235, ordinary low-carbon steel, is divided into construction wire rod and wire drawing and high-quality carbon structural steel No. 10, No. 15, and No. 20 (generally carbon less than 0.3%).
2). Hardwire, high-quality carbon structural steel, the main steel grades are 45~80# steel, 40Mn~70Mn steel, T8MnA, T9A, T10A (generally carbon greater than 0.3%).
3). Welding wire, wire rod for welding rod. Including carbon structural steel electrode steel and alloy electrode steel wire rod. Example H08A, H08E, H08C.
4). Alloy steel, mainly low alloy steel hot-rolled wire rod and alloy steel hot-rolled wire rod. Low alloy steel wire rod 12Mn, 30Mn, 09Mn; alloy structural drawing steel wire rod 20Mn, 30Mn2, 20CrMnSi, 30CrMnSi, 50CrVA; bearing steel wire rod GCr6, GCr9, GCr15, GCr15SiMn; stainless steel plate 1Cr18Ni9Ti, 1Cr13, 2Cr13, 3Cr13 and other alloys Tool steel wire rod.
