Mixed acid and hydrofluoric acid can be used for pickling of cold drawn tube blanks. Carbon structural steel pipe billets and alloy structural seamless steel pipe billets are pickled with pickling

Aluminum nitride is the main corrosion inhibitor for grain-oriented silicon steel. In addition to adding nitrogen during steelmaking, it can also be nitrided after decarburization to increase the amou

There is only one factor that determines the performance of cold-drawn tubes, and that is chromium. Every stainless steel contains a certain amount of chromium. The fundamental reason why chromium bec

1. The outer diameter is small. 2. High precision, can be produced in small batches

The difference between precision cold drawn tube and seamless steel tube 1. The main feature of seamless steel pipe is that it has no welded joints and can withstand greater pressure. Products can

1. Improve the surface roughness, and the roughness basically reaches RA≤0.08 microns; 2. Correct roundness, ellipticity can be ≤ 0.01 mm.

Precision cold-drawn tube weight formula: [(outer diameter wall thickness)*wall thickness]*0.02466=kg/M (weight per meter), suitable for accuracy and flatness of automobiles, motorcycles, refrigeratio

Daily use of precision cold drawn tubes: The main purpose is to improve the quality of 45# precision steel pipes, including: (1) For low carbon steel and low alloy steel, normalizing can increase i

Precision cold drawn tube is a seamless steel tube produced by cold drawing process. The main application of precision cold-drawn tubes: automobiles, motorcycles, refrigeration equipment, hydraulic pa

The energy-saving requirements of cold-drawn pipes and the society's call for restoring the natural environment are also getting higher and higher. In order to meet these requirements, new cold-drawn

Seamless Honed Pipe Cold Drawn Tubes are economical steels. Cold-drawn tubes include non-circular section, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness

Cold-drawn pipe is a hollow steel pipe with round, square and rectangular cross-sections that is produced without joints on the entire steel pipe surface by drawing, extrusion, perforation, etc. Durin
