What does AISI SAE 4140 mean?
AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.
What is AISI 4140 ASTM equivalent?
AISI 4140 Steel / 42CrMo4 steel is a Alloy Structural Steel belong to ASTM A29/A29M Steel Grade standard.
What is the hardness of 4140 steel?
4140 (modified) Cold Finished, Annealed Alloy Bar Stock Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI. Its wear resistant properties far exceed that of “cold roll” steels.
Is AISI 4140 magnetic?
The magnetic properties of five different microstructures of AISI 4140 steel are measured as a function of compressive plastic deformation. Coercivity, hysteresis loss, remanence, permeability, differential permeability, and anhysteretic magnetisation are determined for strains of up to 10%.
What is the tensile strength of 4140?

Is AISI 4140 a stainless steel?
Introduction. Austenitic stainless steel (AISI 304) and low alloy steel (AISI 4140) possess a good combination of mechanical properties, formability, weldability, and resistance to stress corrosion cracking and other forms of corrosion [1], [2].
Is 4140 harder than stainless steel?
4140 is a chromium and molybdenum alloy steel that has an excellent weight to strength ratio. It is considerably stronger than standard steel. Although it is chromium steel and often referred to as “chromoly steel” it does not contain as much chromium as stainless steel.
What is the tensile strength of 4140 steel?
What are the properties of AISI 4140 alloy steel?
The following table outlines the mechanical properties of AISI 4140 alloy steel. Properties. Metric. Imperial. Tensile strength. 655 MPa. 95000 psi. Yield strength. 415 MPa.
How do you temper an AISI 4140?
Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air.
What is Sasae 4140 steel?
SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature.
What is the welding temperature of 4140 steel?
Material 4140 forging temperature is about 1232 °C (2250 °F). All common arc welding processes, such as (SAW, SMAW, FCAW, GMAW, GTAW) can be used to weld 4140 alloy steel, but in order to prevent cracking, it must be preheated to 170-350 °C (350-650 °F) before welding, preheating interpass temperature depends on the section thickness of the steel.
