The use of carbon steel is extremely popular. Let’s examine why this is the case and what are its most important features that affect its applicability.
Introduction carbon steels – what is it and what’s its chemical composition?
AISI 1075 is a higher carbon steel. It is made in accordance with ASTM A510/A510M, ASTM A713/A713M and SAE J403 and other regulatory documents. Unfortunately, this grade is not suitable for welding due to heat treatment, as cracking may occur. It consists primarily of carbon, as there is as much as about 0.73% of it. It is its alloying element. However, that’s not all. Other elements that make up carbon steel of the AISI 1075 grade are, for example, copper, chromium, nickel, aluminum, molybdenum. Manganese and silicon can also be found in it. Its physical properties include a density of 7.9 g/cm3 and a melting point of 1410 degrees Celsius (2570 degrees Fahrenheit). This makes AISI 1075 carbon steel an extremely versatile material, not least because of its high durability in the fully hardened state. It is used to make cutting tools, especially knife products such as knives, daggers and replica weapons. It is also readily used for making springs.
What is the difference between AISI 1075 and lower carbon steels?
Low carbon steels and high carbon steels such as AISI 1075 differ primarily in their carbon content. AISI 1075 carbon steel has much more of this element in its composition. For this reason, it is a much more brittle material. It can crack more easily than lower carbon steels. Its mechanical properties are also noteworthy. These include a tensile strength of 620 MPa (90,000 psi) and a yield strength of 520 MPa (75,000 psi). This makes AISI 1075 carbon steel ideal for parts requiring high hardness and strength.
Physical properties of AISI 1075 – what is this steel useful for and what are the advantages of using it?
Carbon steel AISI 1075 is used primarily for creating cutting tools. All kinds of knives, blades, and daggers are most often made from this material. It is also a great choice for beginners who want to take up knife making. In addition, it is used to make all kinds of springs, spindles, and clutch discs in many different sizes. Carbon steel AISI 1075 is also used to make engine valves and other parts of various kinds that work under frictional conditions. In addition, it is also used to make parts for high-temperature applications, such as heat exchangers. It is also used in the defense industry for the manufacture of weapons. The biggest advantages of this material are its high hardness and strength, as well as its resistance to wear. Carbon steel is also resistant to corrosion.
What is the production and heat treatment of AISI 1075 carbon steel?
AISI 1075 carbon steel has a machinability index of 50 and can be formed using conventional methods. To prevent cracking, if you want to weld using normal welding methods it is preheated at 260 to 315 degrees Celsius (500 to 600 degrees Fahrenheit) and then reheated at 649 to 788 degrees Celsius (1200 to 1450 degrees Fahrenheit). It is quenched at 899 degrees Celsius (1,650 degrees Fahrenheit) and then tempered in oil. Forging is done at 927 to 1204 degrees Celsius (1700 to 2200 degrees Fahrenheit). It is hot worked at 94 to 483 degrees Celsius (200 to 900 degrees Fahrenheit). Annealing of AISI 1075 carbon steel is carried out at 926 degrees Celsius (1700 degrees Fahrenheit), followed by slow cooling in the furnace. When it comes to cold working: AISI 1075 carbon steel can be cold worked using conventional methods such as rolling and drawing. It can be formed by conventional techniques by bending and shaping.
When deciding to use AISI 1075 carbon steel, be sure to always take it from reliable sources. A good manufacturer will provide the highest quality material, while also being able to provide the necessary advice and assistance. What’s more, you should also remember to carefully read all information about the steel. This will allow you to choose the best grade for your project. It is worth noting that very often it is the type of steel that determines whether the made product will be able to fulfill its purpose.
