II. Application fields

1. Mechanical manufacturing industry

Its high strength and good toughness ensure that the manufactured parts, bearings, etc. can withstand high-intensity use under complex working conditions, reduce the occurrence rate of equipment failures, and extend service life; used to manufacture mechanical parts, bearings, gears, bolts, etc.

2. Chemical industry, ocean, etc.

In fields with extremely high requirements for material corrosion resistance, the 16.0-18.0% chromium and 0.10-0.60% titanium contained in 1.4512 stainless steel bars give it excellent corrosion resistance and can be used stably for a long time in harsh environments such as high humidity and salt spray, effectively reducing equipment maintenance costs.

3. New energy vehicles

Its good mechanical properties and corrosion resistance are expected to play a greater role in the manufacture of automotive parts, helping the new energy vehicle industry to improve product quality and performance.

III. Precautions

1. Usage

Although 1.4512 stainless steel bars have good corrosion resistance, their applicability should be carefully evaluated when they are in contact with certain highly corrosive media, such as high-concentration sulfuric acid and hydrochloric acid, to avoid material performance degradation or equipment damage due to media corrosion.

2. Processing

• Cold processing: It may cause material processing hardening, affecting subsequent processing and performance. The processing deformation should be reasonably controlled, and the plasticity of the material should be restored through annealing treatment when necessary;

• Hot processing: The temperature should be strictly controlled within the range of 800-950°C to prevent overheating from causing coarse grains and reducing material strength and toughness.

3. Storage

Stainless steel bars should be placed in a dry and ventilated environment to avoid direct contact with humid air and other metal materials to prevent electrochemical corrosion or surface oxidation, which will affect their appearance and performance.

IV. Conclusion

The dual breakthroughs in the production and application of 1.4512 stainless steel bars not only bring new development opportunities to related companies, but also promote many industries to develop in the direction of higher quality and higher efficiency. With the deepening of research and development and the continuous expansion of application fields, 1.4512 stainless steel bars are expected to play a greater role and create more value in the future.
