At Owens Industries, we leverage various grades of alloy steel in our CNC machining services to ensure the perfect match for your project needs. Discover the distinctions and applications of these different alloy steel grades, as they form the backbone of our precision-focused, high-quality services. Make an informed decision and get the best results with us. We work with all types and grades of alloy steel. The following is a list of some of the types of alloy steel we use.
Alloy Steel 1.7131, also known as 16MnCr5, is a case-hardening steel with excellent wear resistance and strength. It is often used for manufacturing gears, shafts, and other transmission components due to its high surface hardness and toughness. The addition of manganese and chromium provides improved hardenability and wear resistance. This steel is easily machinable in the annealed condition and responds well to heat treatment.
Alloy Steel 4140, chromium-molybdenum steel, is known for its high tensile strength, toughness, and fatigue resistance. It is widely used in manufacturing automotive components, axles, and oil and gas industry equipment. This steel can be heat treated to achieve a wide range of mechanical properties and has good machinability in the annealed condition. Its versatility makes it a popular choice for applications requiring both strength and impact resistance.
Alloy Steel 1.7225, also known as 42CrMo4, is a chromium-molybdenum steel with excellent strength and toughness. It is commonly used in the automotive and aerospace industries for manufacturing high-strength components such as crankshafts, gears, and connecting rods. This alloy steel offers good hardenability and is suitable for various heat treatment processes. Its high fatigue strength makes it ideal for applications where resistance to wear and impact is crucial.
Alloy Steel 4340 is a nickel-chromium-molybdenum steel with exceptional strength and toughness. It is commonly used in aerospace and automotive applications, including aircraft landing gear, axles, and high-performance engine components. This steel has excellent hardenability and responds well to heat treatment, making it suitable for various strength and toughness requirements. Its good machinability and resistance to fatigue make it a popular choice for demanding applications.
Alloy Steel 1215 is a low-carbon, resulfurized free-machining steel with excellent machinability and surface finish. It is often used for high-speed screw machine parts, bushings, fittings, and other applications where good surface finish and dimensional accuracy are critical. However, due to its low carbon content, it has lower strength and hardenability compared to other alloy steels. It is best suited for applications that do not require high strength or wear resistance.
Alloy Steel 1018 is low-carbon steel with good ductility, weldability, and machinability. It is often used for general-purpose applications, such as structural components, shafts, and gears. Although it does not have the high strength or hardenability of other alloy steels, it can be case-hardened to improve its wear resistance. Its excellent formability makes it a popular choice for applications requiring easy fabrication and machining.
Alloy Steel 4130, a chromium-molybdenum steel, is known for its high strength, toughness, and resistance to atmospheric corrosion. It is widely used in the aerospace and automotive industries for manufacturing structural components, such as aircraft frames and automotive roll cages. This steel offers good weldability and responds well to heat treatment, making it suitable for various strength requirements. Its combination of strength and ductility makes it an ideal choice for demanding applications.
Alloy Steel 4140 PH (pre-hardened) is a version of 4140 alloy steel that has been heat treated to achieve a specific hardness and strength level. This pre-hardened steel offers excellent strength, toughness, and fatigue resistance, making it suitable for applications that require high mechanical properties without additional heat treatment. Common uses include gears, shafts, and heavy-duty machinery components. Its machinability is lower compared to annealed 4140, but it still provides a good balance between strength and machinability for various applications.
Alloy Steel A36 is a low-carbon structural steel known for its excellent weldability, formability, and machinability. It is widely used in construction, including structural components such as beams, columns, and support plates. Although A36 does not offer the high strength or hardenability of other alloy steels, it provides good ductility and impact resistance. Its versatility and ease of fabrication make it a popular choice for various applications in the construction industry.
A2 Tool Steel is an air-hardening, medium-alloy, cold-work tool steel with excellent dimensional stability and wear resistance. It is commonly used for making cutting tools, dies, and punches, particularly in applications requiring high wear resistance and moderate toughness. A2 Tool Steel offers good machinability and can be heat treated to achieve various hardness levels and desired mechanical properties. Its combination of wear resistance and dimensional stability makes it ideal for precision tooling applications.
O1 Tool Steel is an oil-hardening, high-carbon, cold-work tool steel known for its excellent wear resistance, dimensional stability, and toughness. It is commonly used for making cutting tools, dies, and punches in applications where precision and long tool life are critical. O1 Tool Steel offers good machinability and responds well to heat treatment, allowing for a wide range of hardness levels and mechanical properties. Its combination of wear resistance, stability, and toughness makes it a popular choice for high-quality tooling applications.
