Drive Shafts
Drive shaft which is also known as propeller shaft (prop shaft), or Cardan shaft is a mechanical component for transmitting torque and rotation.
Ju Feng supplies high-strength steel materials for automotive and industrial drive shafts.
In order to allow changes in the alignment and distance between the driving and driven components, the drive shaft contains one or more universal joints and couplings. Therefore, their materials must withstand strong pressure, while avoiding excessive additional weight to increase reverse inertia.
The materials for drive shaft application that we recommend are as below.

SNCM420 Alloy Steel
Equivalent Grades: JIS SNCM420 and ASTM 4320. SNCM420 is mainly used for railway bearings, drive shafts, gears, screws, cutting tools and other products which need impact resistance and wear resistance. SNCM420 is a kind of alloy carburizing steel as SNCM220. The mechanical properties between SNCM420 and SNCM220 are almost the same. The surface of SNCM420 is high hardness and has good performance in abrasion resistance and contact fatigue strength. Its core which has high toughness can withstand high impaction. There are two differences between SNCM420 and SNCM220 which are the standard and the amount of Ni content. The Ni content of SNCM420 is more than the one of SNCM220.

SCM440 Alloy Steel
SCM440 is medium carbon chromium molybdenum alloy steel, which is an alloy steel containing chromium and molybdenum. It has the advantages of stable composition, low harmful elements, high steel purity, small decarburization layer and few surface defects. It is easy to be spheroidized and has low cold cracking rate. It is usually hardened and tempered. The ultimate tensile strength is 850-1000 MPa. This material achieves a very good balance between strength, toughness and wear resistance. The chromium content of the alloy provides good hardness permeability, and the molybdenum element imparts average hardness and high strength. SCM440 reacts well in heat treatment and it is easy to process under heat treatment conditions. This material provides many desirable properties such as good strength and wear resistance, excellent toughness, good ductility and resistance to high-temperature stresses.
