AISI 4140 alloy steel can be tempered at 205 to 649C (400 to 1200F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316C (600F), and a tensile strength of 130 ksi can be achieved by tempering at 538C (1000F).

Yield strengths range from 110 ksi through 140 ksi, but we can temper it to. other strength levels. When compared with standard 4140 heat treated to. the same tensile and yield strengths, 4140HW achieves significantly higher. toughness, as measured by impact strength (see Figure 9).
4140 steel is chromium, molybdenum, manganese steel with good toughness, impact resistance and fatigue strength. 1045 has slightly increased tensile strength and yield strength numbers than 1045 as a result of a slightly higher carbon content. Also, as a result of higher carbon content, 1045 is not as easy to weld as 4140.

Introduction. The AISI 4140 cold finished annealed chromium-molybdenun alloy steel can be heated using various methods to yield a wide range of properties, hence it is often used as stock for forging as it has self-scaling properties. AISI 4140 is capable of resisting creep in temperatures up to 538Cbest 4140 steel yield strength psi
Among commonly used metal alloys, stainless steel and tempered structural aluminum have relatively high tensile strengths: 90,000 and 45,000 PSI, respectively. Impact Strength Impact strength is a measure of how much impact or suddenly applied force a metal can take before it fails.
Chemical Properties. The chemical properties of 4130 and 4140 steel are similar aside from differences in Carbon and Manganese concentrations. Carbon, C 0.30% 0.40% Manganese, Mn 0.40-0.60% 0.75-1.00% Chromium, Cr 0.80-1.10% 0.80-1.10% Molybdenum, Mo 0.15-0.25% 0.15-0.25%.
Mild steel has a yield strength of 60,200 pounds per square inch (psi), a tensile strength of 78,300 psi, a modulus of elasticity of 29,000 psi, and a Poisson's ratio of 0.29. The yield strength of a material is the stress at which plastic deformation of the material begins to take place.
4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.

SAE AISI 4140 Alloy 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.
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.
