300M (4340 Mod) Alloy Steel Applications:This grade is used high strength structural applications with sections 3.5 in and under in cross-section thickness for through-hardness requiring minimum Rockwell C hardness 52 HRC that are subject to exacting magnetic
300M Alloy Steel (4340M) - Rough Turned & Vacuum Arc 300M steel is a vacuum melted low alloy steel with the inclusion of vanadium and a higher silicon composition. It has a very good fatigue strength and resilience. Where fracture toughness and impact strength are crucial, 300M is a great choice.
4340. This nickel-chromium-molybdenum alloy steel is a very high strength steel. It is sought after for its toughness and for being used as a steel that will be highly stressed. It is used in a variety of industries for different applications including the automotive, aerospace, and tooling industries.

4340 Annealed - Welcome to Pacific Machinery & Tool Steel When properly hardened, 4340 exhibits a good combination of strength, ductility and toughness; this is the material to which other ultra-strength steels are compared. PACIFIC 4340 Heat Treated bars are hardened to 285/331 HB and meet ASTM A 434, Class BD. 4340 is weldable but only with proper precautions; because of its high hardenability, it requires both preheat and post heat in virtually all
This can result in lower case hardness or longer nitriding cycle times for steels containing nickel such as 4340. Stress Relieving Heat to 600 o C - 650 o C, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm section, and cool in still air.

Is 4340 Steel Good For Knives? 7 Answers You Should Know 4340 is an excellent steel for applications where strength is the most important factor, and sharpness is not as important as throwing knives and axes or blunt tools such as hammers. Knife steels typically have a carbon range between 0.7% and 1.2%, while 4340 maxes out at 0.43% carbon. The high hardenability and resistance to fatigue make this alloy ideal for applications such as forged hydraulics and

4140 is an alloy of steel that shares many qualities, such as its toughness and general forging temperatures, with 4340 steel. Its chromium content makes it very hard, and it maintains uniform hardness and strength throughout. This uniform hardness is important for hammers because it prevents weak spots in the metal that could cause it to break.AISI Alloy Steel 4340Mar 06, 2015 · 4340 ALLOY STEEL. General Characteristics of Alloy Steel 4340 forged steel crankshafts. Forging. Forging should be carried out between 2250 and 1800 the lower temperature range is used. Hardening. This heat treatment results in the formation of martensite after quenching, resulting in increased hardness and tensile strength.
