What do you know about Steel File Set?

Steel File Set is a kind of work of sheet metal workers. Steel files have long triangular edges, long cones, long semicircles and so on. The shapes, lengths, and thicknesses vary. The common point is that the small diamond-shaped burrs on the surface are very hard, and the surface of steel, iron and other objects (parts) can be smoothed and smoothed.

What is the production process of Steel File Set?

1. The hardness of Steel File Set is usually above 60HRC. From the perspective of chemical composition, the carbon content is very high, generally 1.0~1.3% carbon content is required, and heat treatment must be carried out at the same time, otherwise even if the carbon content is high, it will not reach such high hardness.

2. Steel File Set usually adopts the heat treatment of quenching + low temperature tempering, so that high hardness martensite structure can be obtained, and the steel knife can maintain high hardness.

What is the hardness of the Steel File Set?

Steel File Set is very hard. Around 62 to 67HRC.

Material Regular Steel File Set is the material with the highest carbon content of T12 or T13, the two carbon tool steels. The state of the file is very brittle. It is not allowed to be used as a hammer or crowbar during normal operation. It is also normal to break from a high drop, and it is not suitable for everyday knives.

The hardness of general steel files is usually above 60HRC.

From the perspective of chemical composition, the carbon content is very high, generally 1.0~1.3% carbon content is required, and heat treatment must be carried out at the same time, otherwise even if the carbon content is high, the hardness will not be so high. Under normal circumstances , Usually the heat treatment of quenching + low temperature tempering is used, so that a high hardness martensite structure can be obtained and high hardness can be maintained.

What are the classifications of Steel File Set?

Steel File Set, like files, can be roughly divided into three categories: ordinary files, special files and plastic files (assorted files);

Ordinary files are divided into five types: flat files, square files, triangular files, semi-circular files and round files according to the shape of the section of the file. Rectangular holes and narrow planes; triangular files are used to file inner corners, triangular holes and planes; semicircular files are used to file concave arcs and planes; round files are used to file round holes, concave arcs and elliptical surfaces with smaller radii. Special file is used to file the special surface of parts, there are two kinds of straight and curved;

The shaping file (assorted file) is suitable for trimming small parts of the workpiece, and there are many files with various cross-sectional shapes to form a set.
