Forging Good Fatigue Resistance 4140 Steel For Sale Manufacture - China

High strength, hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature.

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m.

4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature.

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines.

Test

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 )HRB

2 - 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 matrix LCD

5 - Data storage: maximum 500 groups (impact times 32 to 1)

6 - Working voltage: 3V (2 AA size alkaline batteries connected in series)

7 - Continuous working time: about 100 hours (when the backlight is not turned on) Dongguan Songshun Mould Steel Co., LTD
