72+ pages what is the difference between 4140 and 4340 steel 1.8mb. This steel can be case hardened by simply lowering the temperature during the quenching. For each property being compared the top bar is SAE-AISI 4140 steel and the bottom bar is SAE-AISI 4340 steel. There are various methods of hardening 4140 alloy steel. Read also 4140 and understand more manual guide in what is the difference between 4140 and 4340 steel This contributes to substantial differences in hardenability and fracture toughness and also has a positive effect on distortion during quenching and corrosion resistance.
They have a very high 98 of their average alloy composition in common. They are the same alloy.

The H band composition provides the melt shop with a somewhat wider chemical range to assure that they have the degrees of freedom needed to assure that the material will harden within the bands as provided by astm a 304.

JIS G3116 SG325 steel plate sheet and coil for LPG gas cylinder. For steel alloys the first two digits indicate the major alloying elements present and the last two digits give the carbon content in hundredths of a percent. B By the way for 4140 steel we can supply the round bar steel flat bar and plate. JIS G3116 SG295 steel plate sheet and coil for LPG gas cylinder. This means that 4140 and 4150 steels have the same alloying elements chromium and molybdenum but 4150 steel has more carbon. These are quenching heating and cold working.

However for very high strengths the 4340 grade is heattreatable with the least distortion because it does not need to be quenched in water or in cold oil. Quenched and Tempered 4140 Cr-Mo Steel SAE-AISI 4142 G41420 Cr-Mo Steel. But 4340 steel has Nickel content while 4140 steel does not.
Here is all you need to read about what is the difference between 4140 and 4340 steel The Society of Automotive Engineers or SAE and the American Iron and Steel Institute or AISI use a four-digit system to designate the chemical composition of steel. The 4340 is stronger than the 4140. Because of this 4140 is typically more readily available and more cost efficient.
