Purchased as rolled, Pre-Hardened (PH) or in the annealed condition, 4140 steel plate possesses a full range of hardening and wear resistance properties. Due to its good hardness penetration and uniformity, flame hardening, induction hardening, or oil hardening can increase the wear resistance of 4140 steel.
4140 hardened and tempered bar can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.Parts should be heated as quickly as possible to the austenitic temperature range (840 C - 870 C) and "required case depth followed by an immediate oil or water quench, depending upon hardness required, workpiece" size/shape and quenching arrangements.
Material is quench & tempered, stress relieved and machine straightened. We offer an extensive inventory of hard-to-find sizes and lengths including (10/12 Ft Random Lengths, 20/24 Ft Random Lengths and Custom Cut-To-Length options). Alloy 4140 and 4150 are widely used for general purpose machine applications.
Pre hardened and tempered 4340 steels can be further surface hardened by flame or induction hardening and by nitriding. The 4340 steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. AISI 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed.
AISI 4130 can be heated as a way to harden the material. When hardening is desired, the material should be heated at a minimum of 1600 degrees F. followed by an oil quench. The best results can be obtained when heating occurs between 1650 and 1700 degrees, followed by an oil quench and soak of 1600 degrees.

TimkenSteels 4130HW steel is a fine-grained, low-alloy steel that offers optimum heat-treat response in heavier . cross-sections. It is used in a variety of bar and tubing applications in quenched/tempered conditions. Yield strengths range from 80 ksi through 95 ksi but may be tempered to higher strength levels.
Workability: Alloy 4140 is an oil-hardening steel of relatively high harden-ability. Its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. 4140 responds well to heat-treatment and is comparatively easily machined in the heat-treated condition.
4140 Pre Hard 4140PH is a chromium-manganese-molybdenum grade This grade is delivered in a prehardened condition at a hardness level of 33/37HRC The grade has a fully homogeneous martensite- bainite microstructure 4140PH grade has specific sulfur addition (0.060% typical) in order to increase strongly its machinability C S.4 , carbon steel 42crmo4 supplier
4340 Heat Treated HOT ROLLED & COLD FINISHED. PACIFIC 4340 is available in two conditions: heat treated (quenched and tempered) to high strength or annealed for ease of machining and subsequent heat treatment. It is a nickel-chromium-molybdenum medium carbon alloy steel with deep hardenability. It can be through hardened in large sections.
Introduction. They are more responsive to mechanical and heat treatments than carbon steels. They comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels. AISI 4130 alloy steel contains chromium and molybdenum as strengthening agents.
Annealing & Normalizing Steel at Home By Adele Eliot ; Updated September 15, 2017. Annealing and normalizing are two ways of heating steel. Annealing softens the steel, preparing it for shaping and forging. Normalizing is a similar process but hardens the steel once you have finished working on it. Both processes require heat from a furnace or , carbon steel 42crmo4 supplier
AISI 4130 steel has a specialized chemical composition that gives it a unique set of properties. The steel has a carbon content between 0.28 and 0.33 percent, a chromium content between 0.8 and 1.1 percent, manganese content between 0.7 and 0.9 percent, molybdenum between 0.15 and 0.25 percent and a silicon content between 0.15 and 0.35 percent.
In this video we give some basis on how to get some 4140 alloy steel hardened and then temper to different hardness, we will perform our test using a Rockwell hardness tester. This is a basic , carbon steel 42crmo4 supplier

What Is Chromoly Steel? Chromoly steel is a type of low alloy steel that gets its name from a combination of the words chromium and molybdenum two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost.
AISI 4130 steel is usually supplied ready heat treated with a hardness of 18-22HRC. If further heat treatment is required annealed AISI 4130 should be heated slowly to 870-890C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. The steel has good strength and toughness, weldability and machinability. Type 4130 steel should be forged between 2250 and 1750 F (1230 and 950 C.).
I would suggest you remove a sample and have a metallographic examination performed to verify your heat treatment process. This examination will determine if you had achieved a thru-hardened, quenched and tempered microstructure. I would also confirm the chemical composition of the stock to make sure it was 4130 alloy steel.
H13 Tool Steel. H13 Tool Steel is a versatile chromium-molybdenum hot work steel that is widely used in hot work and cold work tooling applications. The hot hardness (hot strength) of H13 resists thermal fatigue cracking which occurs as a result of cyclic heating and cooling cycles in hot work tooling applications.
case-hardened part. Consequently, a high car-bon potential may be suitable for short carbur-izing times but not for prolonged carburizing. Selection of carbon potential also depends on the carburizing response of a particular steel. Carburizing Steels Carburizing steels for case hardening usually have base-carbon contents of approximately
4130 has a machinability rating of about 35%, meaning your speed will be about 1/3 that of mild steel. Using carbide try about 100 SFPM and HSS about 30 SFPM. 38Rc is not a problem with carbide, might have to run slower. 4130 hardens about 1" deep so if you have cross sections exceeding that you should rough machine before HT.
