I think you're looking at two separate terms.
SAE 4140 steel is a Chromium-Molybdenum steel used extensively for axles, aerospace concerns, and firearm manufacture.
Mild steel is a catch-all term for plain carbon steel of low carbon content (such as SAE 1018) which is generally cheap, not heat-treatable, and used for fairly low-strain applications.
I hope that helps.

What else can I help you with?
Is better steel grade 4140 or C45?
Steel grade 4140 is generally considered better than C45 for applications requiring higher strength and toughness. 4140 is an alloy steel that includes chromium and molybdenum, providing superior hardenability and wear resistance. In contrast, C45 is a carbon steel that offers good machinability and moderate strength but lacks the alloying elements that enhance 4140's performance in demanding conditions. Thus, for applications needing enhanced mechanical properties, 4140 is typically the preferred choice.
What is the copper percent in mild steel?
Mild steel, not copper.
Does mild steel have iron in it?
steel is the alloy of iron and carbon , so mild steel is an ferrous alloy
What is the difference between mild iron and mild steel?
Iron is the pure element, mild steel, or any steel is iron with a little bit of carbon added. The iron becomes mild steel, steel or any other type of steel depending on how much carbon is added to the iron.
How can identify Mild steel and stainless steel?
steel it self means the carbon percentage and according to which we have to specify them. mild steel contain low C% nearly 0.3-0.6% is called mild steel. stainless steel having higher C%&Cr is added to not corde
What is 4140 stainless steel?
It's a misnomer. 4140 is a type of steel, which is NOT stainless.
What is the weight of 4140 steel?
The weight of 4140 steel varies depending on the form and dimensions of the material. On average, the density of 4140 steel is around 0.283 lb/in³. Therefore, to calculate the weight of a specific piece of 4140 steel, you would need to know its dimensions and then use the density to calculate the weight.
How much does 4140 steel cost?
The cost of 4140 steel can vary depending on factors such as quantity, supplier, and market conditions. On average, the price for 4140 steel can range from $1.50 to $3 per pound. It's recommended to contact steel suppliers directly for the most up-to-date pricing information.

What is the equivalent material for 4140 grade steel?
EH 36
What is the density of 4140 grade steel?
0.282-0.283 lb/in3
Which is heavier stainless steel or mild steel?
mild steel is heavier
Which is more hard lead or mild steel?
Mild steel
What is the copper percent in mild steel?
Mild steel, not copper.
Is mild steel inlcudes stainless steel?
No, mild steel is low carbon steel with no other alloys.
WHAT DO THE NUMBERS IN 4140 STAND FOR?
The numbers in 4140 typically refer to a type of alloy steel known as AISI 4140. This designation indicates that the steel contains approximately 0.40% carbon, along with chromium and molybdenum as alloying elements. AISI 4140 is known for its high strength, toughness, and wear resistance, making it suitable for a variety of applications, including machinery and automotive components. The numbers help categorize and specify the material's composition and properties.
Is A36 steel mild steel?
Yes. It is considered "Mild" Steel due to the low amount of carbon in the steel.
