What is AISI 4140 Steel?
AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc.Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below.
1.It is low alloy steel with chromium, molybdenum, and manganese.2.Great toughness, fatigue strength, abrasion and impact resistance.3.It is widely be used in the industry due to its exnt versatility and usefulness.4.The higher carbon content in it, the higher the strength and heat treatment capabilities it is.5.It can be oil hardened to relatively high hardenability.
How is SAE 4140 steel tested?
Our AISI 4140 steel round bar and steel plate composition detection is carried out by a spectrometer, which is fast, accurate and efficient in detection; hardness is tested by a hardness tester,The hardness tester is based on the Leeb hardness measurement principle, which can easily and quickly measure a variety of metal materials. While displaying the hardness measurement value immediately, it can be freely converted between different hardness scales, and the tolerance limit can be set in advance, and it will automatically alarm when it exceeds the range.1. Measuring range: (170-960)HLD,(17-68.5)HRC,(19-651)HB,(80-976)HV,(30-100)HS,(59-85)HRA(13-100 )HRB2. Measurement direction: support 360° (vertical down, oblique down, horizontal, oblique up, vertical up)3. Hardness scale: Richter (HL), Brinell (HB), Rockwell B (HRB), Rockwell C(HRC), Rockwell A (HRA), Vickers (HV), Shore (HS)
4. Display: quarter dot >5. Data storage: maximum 500 groups (impact times 32 to 1)6. Working voltage: 3V (2 AA size alkaeries connected in series)7. Continuous working time: about 100 hours (when the backlight is not turned on)
