The AISI 4140 properties include high tensile strength and hardness. AISI 4140 offers good wear and tear resistance in quenched and tempered conditions. AISI 4140 equivalent grades are SAE 4140 and UNS G41400. AISI 4140 hardness is more as compared to other steel grades. AISI 4140 offers high corrosion resistance due to which it is frequently for oil drilling. We Shandong Shanshui Special steel can provide AISI 4140 round bars, forged bars, bright bars and other sizes of premium quality.
Ready stock material of AISI 4140 in sizes 20mm to 190mm dia. Round bar supplier of AISI 4140 for over two decades. We are one of the most trusted manufacturer and exporter of AISI 4140 grade steel Bars. Heat Treatments such as normalizing, tempering, quenching, etc can be applied to AISI 4140. It is used to make chains, screws, gears, arms, rollers, and other machine parts.
SAE 4140 steel is a low-alloy steel grade under the standards of the American Society of Automotive Engineers(SAE).
In the quenched and tempered condition, SAE 4140 steel has good strength, toughness, wear resistance and fatigue resistance.Therefore, SAE 4140 steel is usually delivered in the pre-hardened condition(PH) with hardness 28-34HRC.
SAE 4140 alloy steel has many applications as forgings in the automotive, aerospace, oil and gas industries, typical uses are forging gears and shafts, spindles, clamps, clamps and collars.

What is the difference between ASTM 4140,AISI 4140 and SAE 4140?
First of all, let's make it clear that SAE, AISI and ASTM represent the three major American associations, namely the Society of Automotive Engineers (SAE), the American Iron and Steel Institute (AISI), and the American Society for Testing and Materials (ASTM).

Hot rolled round steel is a common steel product, which is heated at high temperature and processed by a special rolling process on the roller table unit. Here are some details about hot rolled round steel:
Material: Hot rolled round steel is usually made of carbon steel, its main components are carbon and iron. According to actual needs, other elements can also be added, such as manganese, silicon, sulfur, etc., to improve the performance of the steel.
Processing technology: Hot rolled round steel is processed under high temperature conditions, the general working temperature is above 1000°C. First, the billet is heated to the appropriate temperature and then rolled through a roller unit to gradually deform from a billet or bar to a round shape.
Features: Hot rolled round steel has the following characteristics:
High strength: The steel processed by hot rolling has high strength and can withstand greater pressure and load.
Good plasticity and machinability: hot rolled round steel can further change its shape and size through cold processing and other ways to meet different needs.
Good surface quality: due to high temperature rolling, the surface of hot rolled round steel is smooth and has no obvious defects.
Application: Hot rolled round steel is widely used in construction, machinery manufacturing, automobile manufacturing, ship construction, petrochemical and other industries. It is often used to make components, bearings, shafts, guide rods, mechanical parts and so on.
Heat treatments applied on AISI 4140 round bars are annealing, quenching, hardening, normalizing, tempering, etc. Heat treatments can vary the mechanical properties of the SAE 4140 alloy steel. The AISI 4140 material is tested for a variety of parameters such as impact testing, mechanical testing, chemical analysis testing, bent testing, etc. Heat Treated AISI 4140 round bars are of very tensile strength and are used to make steel products.
