Q420C
Hot-rolled alloy steel is a type of steel produced through a high-temperature rolling process. During its manufacturing, the steel is heated above its recrystallization temperature and then shaped using rolling mills. This high-temperature treatment gives the steel good ductility and toughness, and effectively removes internal stresses. Hot-rolled alloy steel is widely used in construction, machinery manufacturing, the automotive industry, and shipbuilding due to its excellent mechanical properties and workability.
