Reviewed and maintained by the Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd.

Material Performance

1. Mechanical properties

: Density of 4.51g/cm ³, reducing weight by about 40% compared to 304 stainless steel, with higher specific strength; Annealing tensile strength ≥ 440MPa, elongation at break ≥ 20%, good cold working and argon arc welding forming performance.

2. Corrosion resistance

: The surface can quickly form a stable and dense oxide passivation film, which is resistant to corrosion by seawater, chloride ions, dilute acid and alkali, and wet chlorine gas. Its anti-corrosion performance is significantly better than 316L stainless steel; Not suitable for concentrated oxygen free hydrochloric acid and pure hydrofluoric acid media.

3. Special physical properties

: non-magnetic, excellent low-temperature toughness, and not easily broken even at minus 253 ℃; The material is pure and free of heavy metal precipitation, which will not contaminate the transported materials and meet the requirements of clean production.

Process Structure

1. Seamless integrated structure

: hot extrusion+cold rolling forming, the entire pipe has no welds, and there is no risk of weld corrosion or leakage. It has stronger pressure bearing capacity and is suitable for high-pressure anti-corrosion equipment.

2. Vacuum heat treatment structure

: The entire process of vacuum annealing eliminates residual internal stress from cold rolling, and the pipe is not easily deformed or cracked after long-term use, with no heavy oxide layer on the surface.

3. Internal and external surface structure

: acid pickling and passivation treatment, smooth and flat pipe wall, low fluid resistance, and less likely to scale and block the pipeline; The finished product has undergone dual inspections of ultrasonic testing and hydraulic pressure testing, with no hidden defects such as delamination, cracks, or pores inside, and a long service life.

Application Fields

1. Chemical industry

: Chlor alkali electrolysis equipment, acid-base heat exchangers, corrosive medium transport pipelines, reactor cooling coils;

2. Seawater and environmental protection industry

: seawater desalination condensers, ship cooling pipelines, power plant desulfurization pipelines, offshore oil platform anti-corrosion pipelines;

3. Pharmaceutical and semiconductor industries

: high-purity liquid medicine delivery pipelines, vacuum clean pipelines, meeting sterile and precipitation free production standards;

4. Electric power industry

: nuclear power, thermal power anti-corrosion heat exchange tubes, high-voltage corrosion-resistant process pipelines.
