AISI 4130
AISI 4130 Forged round bar


AISI 4130 is a low alloy steel which contains nominally at least 0.28% Carbon, 0.8% Chromium and 0.15% Molybdenum as strengthening agents. It has good strength ,toughness,fatigue strength,and good atmospheric corrosion resistance.Similar to 4140, it has a lower carbon level which gives 4130 improved weldability, at the expense of through thickness strength.AISI 4130 steel is usually used in the quenched and tempered
