AISI 1035 Steel: Explanation, Applications, and Grades
Introduction to AISI 1035 Steel:
AISI 1035 is a medium-carbon steel grade with a carbon content of approximately 0.32% to 0.38% and manganese around 0.60%-0.90%. Known for its balance of strength, hardness, and ductility, AISI 1035 is a popular choice for applications requiring moderate mechanical strength and wear resistance. Due to its higher carbon content than low-carbon steels, it can achieve greater hardness through heat treatments like quenching and tempering. However, compared to low-carbon steels like AISI 1020, AISI 1035 has reduced weldability and requires more careful control to prevent cracking during welding.
Properties of AISI 1035 Steel:
AISI 1035 offers a favorable combination of strength, hardness, and machinability. It is highly responsive to heat treatments, allowing for tailored hardness levels suitable for a variety of applications. AISI 1035 can be used in applications requiring moderate wear resistance and toughness and is often selected for parts needing good durability under dynamic loads. However, its weldability is slightly limited, and cold-forming operations may require pre-heating to avoid cracking. With its versatile mechanical properties, AISI 1035 is well-suited for moderate-stress environments where reliability is crucial.
Applications of AISI 1035 Steel
- Automotive Components:
AISI 1035 is commonly used in automotive manufacturing, particularly for parts like axles, crankshafts, and connecting rods. The steel’s strength and moderate hardness make it ideal for components that must endure repetitive mechanical loads and moderate wear. - Machinery and Equipment Parts:
This grade is suitable for producing machine parts, including gears, sprockets, and bolts. AISI 1035’s machinability and ability to be hardened make it a preferred material for manufacturing high-strength, durable components. - Construction and Structural Applications:
AISI 1035 is used in construction for parts such as shafts, pins, and rods. It is well-suited for building mechanical frameworks and supports that benefit from its strength and toughness. - Agricultural Equipment and Tools:
Due to its durability and wear resistance, AISI 1035 is used in various agricultural tools, such as tillers, plow shares, and harrows. It provides the necessary strength to endure abrasive conditions and mechanical stresses in agricultural environments. - Forged and Rolled Parts:
AISI 1035 steel is widely used for forgings and rolled sections, such as bars, flats, and rounds. This makes it ideal for custom components that require specific shapes and mechanical properties, such as rollers, spindles, and forged shafts. - Industrial Components:
In industrial settings, AISI 1035 is used for components exposed to moderate stress and wear, such as couplings, pump shafts, and compressor parts. Its hardness and wear resistance make it durable in dynamic environments.
