4140 steel is chromium,molybdenum,manganese steel with good toughness,impact resistance and fatigue strength.1045 has slightly increased tensile strength and yield strength numbers than 1045 as a result of a slightly higher carbon content.Also,as a result of higher carbon content,1045 is not as easy to weld as 4140.

ASTM's steel standards are instrumental in classifying,evaluating,and specifying the material,chemical,mechanical,and metallurgical properties of the different types of steels,which are primarily used in the production of mechanical components,industrial parts,and construction elements,as well as other accessories related to them.
