AISI 4140 Alloy Steel / 42CrMo4 / 42CrMoS4 / 1.7225

AISI 4140 alloy steel can be tempered at 205 to 649 42crmo4 rockwell hardness#176;C (400 to 1200 42crmo4 rockwell hardness#176;F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316 42crmo4 rockwell hardness#176;C (600 42crmo4 rockwell hardness#176;F), and a tensile strength of 130 ksi can be achieved by AISI 4140 Steel, normalized at 870 42crmo4 rockwell hardness#176;C (1600 42crmo4 rockwell hardness#176;F), air cooled afnor 40 cd 4, afnor 42 cd 4 (france), astm a322, astm a331, astm a505, astm a519, astm a646, b.s. 708 a 42 (uk), b.s. 708 m 40 (uk), b.s. 709 m 40 (uk), jis scm 4 h, jis scm 4, jis scm440, ss14 2244 (sweden), mil spec mil-s-16974, sae j404, sae

Correlation between thermal properties and hardness of end

Jul 10, 2008 42crmo4 rockwell hardnessnbsp; 42crmo4 rockwell hardness#0183; 42crmo4 rockwell hardness#32;Rockwell hardness evolution with the distance d for the three samples C48, 42CrMo4, 35NiCrMo16. According to these curves, one can notice that the mechanical hardness decreases gradually from the soaked extremity until a distance d of about 50 mm respectively for steels C48, 42CrMo4 and remains constant for the 35NiCrMo16 steel. Correlation between thermal properties and hardness of end The thermal properties, the Rockwell hardness (HRC) and the microstructure of three end-quench bar (Jominy bar) steels (C48, 42CrMo4 and 35NiCrMo16) have been investigated. The thermal properties are determined using photothermal deflection (PTD) technique and the hardness is measured by the Rockwell durometer.

Tensile values are generic, not specifically for 4140. Note that conversion tables rarely agree on Brinell to Rockwell.

Induction Hardening:Achieve Maximum Surface Hardness

To achieve the hardness specified for your part with induction heat treatment, the right steel grade must be selected. The greatest hardness range directly correlates to the carbon content of the steel being used. To help you develop accurate parts and specify reasonable tolerances for hardness and case depth results, Zion Industries has created the following guidelines for the maximum surface Induction Surface Hardening 4140 alloy steelSep 11, 2020 42crmo4 rockwell hardnessnbsp; 42crmo4 rockwell hardness#0183; 42crmo4 rockwell hardness#32;On the most recent bar I heat treated, I took 2 hardness measurements on one end that came out to be 22 and 29, and on the other end I obtained 31, 32 and 24 on the Rockwell C scale.
