Which cold-drawn square steel is of good quality

Which cold-drawn square steel is of good quality? Welcome to Guanghui Metal! !

Cold-drawn square steel is a steel with various cross-sectional shapes and sizes that are processed by cold-drawing. Cold-drawn square steel is also called cold-drawn steel, and cold-drawn square steel can be used in the automotive industry, hardware tool industry, and machining manufacturing, textile machinery processing.

In recent years, the cold-drawn square steel industry has entered mature stage of the market, which means that the market has reached a bottleneck and market sales channels have matured. In addition, the cold-drawn square steel industry has low entry barriers and serious product homogeneity. Therefore, in this mature period of the market, competition is relatively fierce. We all know that a recession will inevitably come after the maturity period, which is the summary of historical experience. If cold-drawn square steel companies want to survive the next recession, they can only take advantage of the current maturity period to innovate vigorously, and rely on their own technology to add a layer of guarantee for their future development.

 Specification of cold-drawn square steel : 16*16mm----50*50mm, Ф4.5—Ф70

Material: 45#, A3, 20Cr, 40Cr, 20Crmo, 40 Crmo, 20Mn2A, 42Crmo, 20Mnsi, 35Crmo, HG3, Q215, Q235, B16, 25Cr2mova, 60Si2MnA, 55CrsiA, 16mn, 40mn, etc., can be customized.

Cold-drawn square steel refers to cold-drawn steel whose forged shape is square.

Cold-drawn steel is to forcibly stretch the steel bar under normal temperature conditions with a tensile stress exceeding the yield point strength of the original steel bar, so that the steel bar will be deformed plastically to achieve the purpose of increasing the yield point strength of the steel bar and saving steel.

 Cold-drawn steel is the use of cold extrusion technology to pull out various high-precision, smooth-surface round steel, square steel, flat steel, hexagonal steel and other special-shaped steel through precise molds.

Cold-drawn steel bars: for the purpose of saving steel and improving the yield strength of steel bars, the method of stretching steel bars with tensile stress exceeding the yield strength but less than the ultimate strength to cause plastic deformation is called cold-drawn steel bars.

Process flow:

Original billet mobilization----Acceptance----Warehousing----Picking----Rolling head----Pickling or shot blasting ----Soapification---Cold-drawing ---Flattening ---Packaging---Weighing and marking----Inspection---Finished product warehousing

Advantage:

Variety of shape specifications

By designing molds of different shapes, cold-drawn steel with different cross-sectional shapes and different specifications and tolerances can be cold drawn. The angle can be designed to be right or round. 

High precision

We use high-quality cemented carbide molds and have professional mold repair personnel to ensure accurate and uniform tolerances.

Smooth surface

Advanced cold extrusion technology makes the surface of cold drawn steel products smooth and bright.

Saving material

The cold drawing process is to make raw materials be the required shape, specifications and tolerances by cold-extrusion. The loss of raw materials is minimal. Comparing with the materials consumed by traditional lathe machining and cutting, the material saved by cold drawn steel is very considerable. Especially when the amount of material is large, the saving cost of material is more significant.

Saving processing time and processing machinery

Because of its accurate accuracy and good surface condition, cold-drawn steel products can be used directly, such as spraying, sanding, bending, drilling, or direct electroplating after fine drawing according to actual requirements, eliminating a lot of machining time and saving the cost of configuring processing machinery

Applications:

Hardware tools, auto parts, standard parts, fasteners, ordinary shafts, machinery manufacturing, light industry, hardware, standard parts, bicycles, automobiles, motorcycles, textile machinery, transformers and other machinery industries.
