Tensile And Hardness Test Results Table. AISI 4130 Aircraft Steel (AMS 6345 / AMS 6346 / AMS 6350)Alloy 4130 (AISI 4130) is a chromium molybdenum alloy steel. Alloy 4130 is a widely used Aircraft Steel due to its weldability, ease of fabrication and mild hardenability. The hardenability and weldability of Alloy 4130 are considered equivalent to 8630 (MIL-S-6250) . AISI 4130 Steel - 25CrMo4 - JIS SCM430 - GB 30CrMo 4130 Steel Forging. Aisi 4130 steel must be forged at the condition of the temperature at the range of 1230º C to 950º C.The 1230º C is maximum. And do not forge after the temperature of forging stock drops below approximately 870. If the finishing temperature of forging is

    What is 4130 Steel? AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level AISI 4140 Chrome-Molybdenum High Tensile SteelAISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.

    Max. attainable Rockwell hardness is C62-C65. Melting point is 2620° F. Yield strength is 108,000 psi. Grade D2 (High-Chrome Air-Hardening Steel) The high chromium and carbon content in this steel provides superior wear resistance and toughness. A low sulfur content makes it difficult to machine. Max. attainable Rockwell hardness is C62-C65. SAE AISI 4140 Steel Properties, Material Heat Treatment Heat treatment to 845 °C, slow cooling from 755 °C at a rate of 14 °C (25 °F)/hour to 665 °C, or rapid cooling to 675 °C for 5 hours isothermal annealing. Tempering. Tempering temperature of 4140 alloy steel can be from 204-649 °C (400-1200°F) after normalizing and oil quenching, and the corresponding Rockwell hardness can be obtained Section H - EMJhardening steel capable of developing hardness as high as Rockwell C 35, and also for parts with greater thickness requiring proportionately lower hardness. It may be used for parts requiring fusion welding. Hardenability and weldability are considered equivalent to 8630.

This number represents the Rockwell Rating. The Rockwell rating is a scale that is used to measure the hardness of a material. An example is stainless steel AUS-8, which usually 57-59 Rc. The Rockwell hardness test is the industry standard for knives.
