SAE4130 steel round bar Factory price

SAE4130 steel round bar is a versatile alloy with good atmospheric corrosion resistance and reasonable strength up to around 600º F (315º C). SAE4130 steel round bar shows good overall combinations of strength, toughness. and fatigue strength.

SAE4130 steel round bar should be forged between 2250 and 1750 º F (1230 and 950 º C.) The lower the finishing temperature from forging, the finer will be the grain size. If the alloy is forged at too low a temperature, there is a risk of the formation of a non-uniform structure in certain areas of the forged part, necessitating a normalizing treatment – prior to further heat treatment – after forging.
