What is 42CrMo steel material used for?

 42CrMo Steel Material is high strength steel. It has great toughness, strength and hardenability. After quenching and tempering treatment, it will get better fatigue limit and shock resistance ability. It usually is used without obvious temper embrittlement after the quenching and tempering treatment. And its low-temperature impact toughness is good. So 42CrMo steel material round bar or sheet was widely used in the big or medium type plastic mold with certain strength and toughness. The properties of 42CrMo are close to the 35CrMo. But the content of carbon and chromium are higher than 35CrMo, so the strength and hardenability are better than 35CrMo material.

Compare with the 35CrMo, 42CrMo is a better option. Due to its great properties, people usually use 42CrMo steel round bar or plate to make the important fittings those with higher strength and bigger cross-section size than 35CrMo. Such as the shaft, gear, connection rod, spring, engine hydraulic cylinder, 1200-2000mm petroleum drill attaches, and etc.

42CrMo Steel Material Chemical Composition

Stand C(%) Si(%) Mn(%) P(%) S(%) Cr(%) Mo(%)
42CrMo 0.38-0.45 0.17-0.37 0.50-0.80 ≤ 0.030 ≤ 0.030 0.90-1.20 0.15-0.25

42CrMo Mechanical Properties

  1. Tensile Strength: no less than 1080 MPa
  2. Yield Strength: no less than 930 MPa
  3. Elongation: no less than 12%
  4. Rate of Reduction of Area: 45%

Application of 4140 chrome bar

Image
4140 is a 1% Chromium - Molybdenum high tensile steel supplied in the hardened and tempered, cold drawn or turned, precision ground, polished, chrome plated and final polished condition, with a typical base metal tensile strength of 850 - 1000 Mpa, plus a typical hard chrome plated surface hardness of HV 1000 - 1150.Characterised by an extremely smooth surface finish with excellent wear and corrosion resistance, coupled with a base material giving high strength and good impact properties, plus good machinability. 4140 hard chrome plated bar is used extensively by the hydraulic and pneumatic industries, and is employed by other industry sectors for a wide range of applications requiring higher strength. Typical applications are: Agricultural Equipment, Hydraulic Cylinders , Hoists, Jacks and other Lifting equipment, Machine Tools, Mining and Earth Moving Equipment, Pumps, Valves, Waste Disposal Transport and Equipment etc. Anbao Hydraulic is a professional manufacturer in

The Production Process Of Chrome Plated OD Tubing

  Chrome plated od tubing is also known as chrome plated hollow bar ,chrome plated tubing a very important part for producing hydraulic piston rods and roller shafts in various machines. The biggest advantage of chrome plated od tubing than normal chrome plated rod is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the hydraulic cylinders . The Production Process Of Chrome Plated OD Tubing Step 1. Get the steel tubes heat treated as per customers’ request. Step 2. Cutting the raw material hollow rod into lengths Step 3. Straightening the hollow rods Step 4. Peeling on the steel hollow rods Step 5. Straightenning Step 6. Grinding the steel hollow rods Step 7. Straightening the ground hollow bars. Step 8. The second grinding process Step 9. Polishing on outer diameter surface Step 10. Chrome plating Step 11. Final polishing Step 12. Final inspection Anbao Hydrualic is a professional  chrome plated ID tubing and hollow bar m
