Liaocheng Precision Tube Factory details the precise cold-drawn tube (extractable tube) for everyone
Precision cold-drawn tube (extractable tube) is a high-precision steel tube material that uses a seamless tube as a raw material for tolerance control and surface light processing. Precise cold-drawing tubes are characterized by high precision, high gloss, good inner wall cleanliness, high pressure and no leakage of steel tubes, cold bending, deformation, flaring, flattening and no cracks, and can be used for various complicated deformations and mechanical processing. The chemical composition of the precision cold-drawn tube includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr.
Precision tube main uses: automotive, motorcycle, refrigeration equipment, hydraulic parts, pneumatic cylinders, and other customers who have high requirements for precision, smoothness, cleanliness, and mechanical properties.
Precision cold drawn tube difference
1, the main features of ordinary seamless steel pipe is no welding seam, can withstand greater pressure. The product can be very rough cast or cold drawn parts.
2. Precision cold-drawn tubes are mainly inner bores, outer wall dimensions have strict tolerances and roughness, and the precision is extremely high.
Cold-brittle alloy steels with body-centered cubic lattices will change from ductile fracture to brittle fracture when the test temperature decreases. Many industrial cold-rolled precision bright steel tubes will undergo embrittlement at room temperature to sub-zero temperature range, which is called cold brittleness.
