45 Carbon Steel Plate : Uses, Composition, Properties
What is steel grade 45?
Is 45 steel a mild steel?
No. Generally, the mild steel is a kind of carbon steel with the carbon content below 0.25%. Strictly speaking, the 45#/S45C/1045 belongs to the middle carbon steel, which the carbon content is approximately 0.45%.
What metal is 45|S45C|1045?
The 45/S45C/1045 is a kind of steel which the carbon content is appromately 0.45% and other elements can not affect its properties obviously.
What is S45C steel equivalent to?
Is 45 steel strong?
Compared with the normal mild steel, the #45/S45C/1045 steel has higher strength and hardness. Taking the hot rolled S235 and S45C for example, the yield strength (Re) of S235 is equal to or higher than 235 MPa while
this value for 45# is gernally 500-600 MPa. The surface hardness of S235 can not be measured while this value for #45/S45C/1045 is 2-5 HRC in general.

The Enduring Charm of Middle Carbon Steel in Manufacturing
For over a millennium, humans have relied on middle carbon steel to craft essential tools and implements. From kitchen knives to farm shovels, this material has proven irreplaceable for certain products, showcasing its unique appeal.
Understanding Middle Carbon Steel
Middle carbon steel, a type of heat-treated steel, initially exhibits a relatively low hardness, ranging from 75-90 HBW. This makes it ideal for processes such as stamping, drilling, and large radius bending. Post-machining, the steel undergoes quenching and tempering to achieve the desired hardness and mechanical properties.
Applications and Advantages
The versatility of #45/S45C/1045 steel makes it particularly suitable for manufacturing components and parts with complex shapes. It offers enhanced strength, hardness, and wear resistance, making it a preferred choice in various industries.
Case Study: Car Safety Buckle
Consider the car safety buckle. During the initial manufacturing stages, the material must be easily stamped, requiring a lower hardness. However, in the later stages, higher strength is crucial. Middle carbon steel, specifically #45/S45C/1045, is chosen for this application due to its ability to meet these contrasting requirements effectively.
In conclusion, the middle carbon steel’s adaptability and durability continue to make it a cornerstone in the production of essential tools and components, ensuring its place in manufacturing for generations to come.

How Is 45 Carbon Steel Made?
The smelting process is basically the same for the #45/S45C/1045 and the normal mild steel, but more requirement for the purtity of steel for 45 steel. During the smelting process, the carbon element is added to the expected value and making the carbon element distriuted evenly by technical method.
What Are The Advantages And Disadvantages Of Using 45 Gauge Steel?
The hardness of #45/S45C/1045 is in the range of 20-50HRC and it has both strength and hardness. In some certain applications circumstance, such as the automotive frame, the strength is required while the hardness is not considered, then the #45/S45C/1045 should not be used and the high strength steel should be considered. In addition, if the components need high hardness values, such as the main blade for branch shears which requires 55-60 HRC, the #45/S45C/1045 can be used but the brittleness is high. Therefore, the #45/S45C/1045 do not have any availability and the high carbon steel such as SK5 or 1095 should be utilized. Furthermore, another obvious disadvantage for #45/S45C/1045 utilization is the heat treatment is essential, resulting in longer processing time and higher cost
The 45/S45C/1045 steel is a kind of high quality raw mateial for tools, farm implements and safety parts. A plenty of components is made by #45/S45C/1045 steel, such as metal fasteners for car seat belts and climbing belts, hardware in strollers, etc
