AISI 4340 steel sheet High strength AISI 4340 steel sheet thickness

4340 steel is nickel-chromium-molybdenum alloy steel. It will get high strength
after the heat treat. And it has good toughness, fatigue resistance, impact
toughness and etc. Its equivalent grade is JIS SNCM439 and DIN 1.6563. The
properties and composition of 4340 steel round bar sheet plate as below.

It is an alloy structural grade which used by the SAE International(SAE), and
it is chrome-nickel low alloy steel. 4340 steel round bar sheet plate will get
high tensile strength, hardness and toughness after heat treatment. It is used
widely in the transmission components of heavy chemical machinery. Different
sections of each part of the casting which cause the temperature difference
stress and phase transformation stress. If you can’t get their laws and
characteristics, you can’t take the right rational processes. The consequence
is that there is a risk of cracking the casting during the casting or heat
treatment. So the control of chemical composition and the choice of the heat
treatment process for the casting are really important.

4340 belongs to the American standard high-strength alloy structural steel,
which is made of high-quality carbon structural steel by appropriately adding
one or more alloying elements (the total content does not exceed 5%).

Corresponding steel number:
China GB steel number 40CrNiMoA, German DIN steel number 36CrNiMo4, German DIN
material number 1.6511, French NF standard 40NCD3, Japanese JIS standard
SNCM439, British BS standard 816M40, American AISI/ASTM4340, American UNS
standard G43400
