OD 12.7-3000mm Q16Mn3 16MnR Cold Rolled Round Steel Bar Solid Hot Rolled Carbon Steel Bar 20# 45#
Product Description
The 20 of 20# steel refers to the carbon content, and the carbon content is 0.2%, which belongs to low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Low carbon steel-carbon content is generally less than 0.25%; medium carbon steel-carbon content is generally between 0.25 and 0.60%; high carbon steelcarbon content is generally greater than 0.60%. In addition to the carbon (C) element and the steel containing a certain amount of silicon (Si) (generally no more than 0.40%) for deoxidation, manganese (Mn) (generally no more than 0.80%, up to 1.20%) alloy elements, No other alloying elements (except residual elements).Features The steel belongs to high-quality low-carbon carbon steel, cold-extrusion hardened steel. The steel has low strength, good toughness, plasticity and weldability. The tensile strength is 253-500MPa, and the elongation is ≥24%. Normalizing can promote the spheroidization of the steel, refine the massive proeutectoid ferrite, and improve the cutting performance of the blank less than 160HBS. The process route of the steel mold parts is: blanking→forging blank→annealing→mechanical rough machining→cold extrusion molding→recrystallization annealing→mechanical finishing→carburizing→quenching, tempering→grinding and polishing→assembly.
