Ju Feng offers the steel material that can be used for machining parts.
Ju Feng offers the steel material that can be used for machining parts.

The material types of mechanical parts include metallic materials, non-metallic materials and composite materials. Metal materials are divided into ferrous metal materials and non-ferrous metal materials. Ferrous metal materials include steel, cast steels and cast irons, which have good mechanical properties (such as strength, ductility, toughness, etc.), and are relatively cheap and easy to obtain. Non-ferrous metal materials have the advantages of low density, good thermal and electrical conductivity.

The materials for machining parts application that we recommend are as below.

  • SCM440 - Ju Feng provides SCM440, GB 42CrMoA, JIS SCM440, ASTM 4140, 4142, DIN 42CrMo4, 42CrMoS4.
    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.

  • S45CBD - Ju Feng provides S45CBD, DIN Ck45, JIS S45C, DIN C45, ASTM 1045, and GB 45 for customers.
    S45CBD
    Medium Carbon Steel

    The surface is smooth after cold drawing, and the main difference with S45C is that the surface can reach rough turning of grade. The post-process can be directly used for milling or grinding, which greatly reduces the processing time. Its characteristics and application are the same as S45C. .Applications requiring strength and impact resistance of the component, because of its high carbon content, therefore, have a higher tensile strength, ductility and wear resistance, but is not suitable for welding or forming. This steel grade can be supplied in many standard shapes, including round, square, hexagonal, and plate. It generally applicative used in nuts and bolts, axles, rollers, springs, wires, wheel frames, rods, engine parts, stamping dies, hammers, lock washers/lock pin gaskets, turbine rotors, railway tracks, cylinder sleeves, hand tools, screws, railway wheels, gears, garden shears, etc.
