8620 steel vs 1045 steel: For the different material comparisons, which one we should choose to use?

8620 steel China suppliers, wholesale, distributors, and stockholder–Dongguan Otai Special Steel Co Ltd. We Otai is a manufacturer and has a large quantity of stock in our warehouse. We supply in Round bar, gauge plate steel, pipe, tube, rod, square, hexagonal, blanks, plate, sheet, precision ground flat bar. Including precision ground bar stock, hollow bar, we provide black surface and black surface alloy steel material.

8620 is the structural steel with the hardenability guaranteed by American standard, and the standard is as follows: ASTM A29/ A29m-2015 (hot forged and cold processed carbon steel and alloy steel bar).

It has high hardenability, no tempering brittleness, good weldability, little tendency to form a cold crack, good machinability, and cold strain plasticity. Generally used in quenching and tempering or carburizing state, used for manufacturing small and medium-sized automobile, tractor engine and gear in the transmission system, oil drilling and metallurgy open mine cone bit teeth and teeth body, manufacturing steam turbine gear whole rotor internal combustion engine connecting rod valve section forgings. At the same time, the surface of 8620 steel after carburizing heat treatment has relatively high hardness, wear-resistance, and contact fatigue strength, while the core retains good toughness and can withstand high impact load. It can be used as automobile bearing, spindle, gear, mechanical parts, and other impact-resistant, wear-resistant workpieces.

1045 steel is one of the commonly used medium carbon steels with an average carbon content of 0.45%.

It has medium tensile properties, good strength, toughness, and wear resistance. It can be treated by annealing, flame treatment, or induction hardening.C1045 is also known as 1045 cold-rolled steel (cold worked), and 1045 hot rolled steel is known as 1045 HR.

1045 material is widely used in industrial applications where higher wear resistance and strength are required, typical applications including Light gears, shafts, axles, spindles, pins, guide rods, connecting rods, bolts, worms, crankshafts, machine components, etc.
