Forged High Strength S45C / C45 High Carbon Alloy Steel Round Bar
S45C high carbon alloy steel
S45C steel is made of electric furnace, open hearth furnace or pure oxygen converter made of all-steel, the steel microstructure uniform, no defects.
The carbon content of more than 0.4%, excellent wear resistance, but ductility decreases, deformation and cracking easily quenching, so the heat treatment is extremely important and must be quenched after tempering to avoid temper brittleness.
Through the ball of the steel treatment, can improve the cutting performance of such carbon steel.
Is a higher strength of a high-quality carbon steel, hardened due to poor, generally used in the normalized state, the higher the mechanical properties, the use of quenched and tempered.
Medium cold deformation, annealing and normalizing machinability than the quenched and tempered. For the manufacture of higher strength parts, such as gears, shafts, piston pins, and less stressed mechanical parts, forgings, stampings and bolts, nuts, pipe.
Tensile strength σb (MPa): ≥600 (61)
Yield strength σs (MPa): ≥355 (36)
Elongation δ5 (%): ≥16
Section shrinkage ψ (%): ≥ 40
Impact energy Akv (J): ≥39
Impact toughness value αkv (J / cm2): ≥ 49 (5)
Hardness: not heat treatment, ≤ 229HB; annealed steel, ≤ 197HB
S45C carbon steel is widely used in machinery manufacturing, the mechanical properties of this steel is very good.
But this is a medium carbon steel, quenching performance is not good, 45 steel can be hardened to HRC42 ~ 46.
So if you need surface hardness, but also hope to play 45 # steel superior mechanical properties, often 45 # steel surface carburizing and quenching, so that you can get the required surface hardness.
Supply status hardness 137 ~ 170HBS, 167 ~ 229HBS, 201 ~ 269HBS
