The basic form of SCM440 Steel | Material SCM440 | Sevit Special Steel

Depending on the needs, people choose different types of SCM440 to use. So what are the basic types of SCM440 steel?
As readers already know SCM440 is chrome and molybdenum steel. Thanks to these 2 components, SCM440 steel is able to withstand abrasion and strong impact. Besides, this steel line has 2 basic types: solid plate and round. Let's learn about the basic types of SCM440 steel and their application in the following article.

1. SCM440 steel form is solid dense

a. Specification of steel production standard SCM440

- According to Korean standards: Diameter from Ø28 mm - Ø200 mm; Length 6000 mm.

- According to Japanese standards: Diameter from Ø20 mm - Ø200 mm; Length 5700 mm.

- According to Taiwan standards: Diameter from Ø16 mm - Ø600 mm; Length 3000 - 6000 mm.

b. Application

SCM440 steel is a chromium - molybdenum steel line often used in machinery and precision engineering due to its high resistance to deformation and abrasion. Common applications of SCM440 solid steel include:

- Gears: A part that plays an important role in almost all types of machines. The working environment of gears often has the following problems: Bearing the load changing periodically, the root area is easily destroyed due to high stress stress, the surface is abrasive due to friction, the possibility of being crash. It is from these requirements that material SCM440 is most commonly used in gear making applications.

- Transmission shaft: A part of a machine that performs a transmission function. Therefore, the drive shaft is often subjected to high tensile forces, friction, and torsion, which requires steel to be flexible and of high rigidity so that it does not break during operation. Material SCM440 usually makes the transmission shaft stiffness from 52 HRC - 55 HRC.

- Anchor bolts: SCM440 steel has tensile strength from 8.8 to 11 and elongation up to 20% depending on hardness. For anchor bolts, depending on the tensile strength needed, we will heat treatment on different hardness. In addition, SCM440 steel has good ductility and resistance to deformation, thanks to these factors, in the process of using an anchor bolt of SCM440 steel, it does not break or break the threads.

2. SCM440 steel plate form

a. Standard specification of SCM440 steel sheet production

- Thickness: 16 mm - 120 mm.

- Width: 1000 mm.

- Length: 6000 mm.

b. Application

Besides mechanical properties, thanks to diverse specifications, SCM440 steel sheets are widely used in manufacturing tooth rods, molds, machine parts, ...

- Tooth rods: A part of a straight and flat shape that is fitted with a gear to turn a circular motion into a linear motion and vice versa. Technical requirements for gear rods include: Teeth with good fatigue resistance, high rigidity, good wear resistance, stable transmission, no noise. Because of the above requirements, people often use SCM440 steel plate as a bar. Because SCM440 is a steel with high hardness, abrasion resistance, high friction, good deformation resistance, hardness after heat treatment (quenching) reaching 52 HRC - 55 HRC.

SCM440 steel plate

- Pellet molds: Molds of pellet presses can be made from a number of different materials but must meet a number of requirements: Mold deformation is minimal, withstanding large compressive forces, limiting being abrasive, and ensure good tablet product surface. To minimize mold jams, users should choose a mold made from SCM440 steel plate.

- Rice husk injection mold: The material husks are put into the molding machine, the automatic drying unit of the machine will reduce the humidity to below 12%, then press hardwood rods, long tubes. Because rice husk has a high silicon content, it requires materials with high abrasion resistance. In addition, the injection mold is also influenced by forces such as compression, friction and heat. Through the above requirements, it is easy to see that SCM440 steel is the optimal choice that can meet all the above requirements.
