316Ti Stainless Steel Plate

I. Performance characteristics of 316Ti stainless steel plate

1. Advantages of intergranular corrosion resistance

By adding 0.2%-0.7% titanium, a stable TiC compound is formed, which effectively inhibits the precipitation of chromium carbide, avoids the phenomenon of chromium depletion at the grain boundary, and significantly improves the anti-sensitization ability in the high temperature range of 550-800℃.

2. Enhanced corrosion resistance

(1) Molybdenum (1.8%-2.5%) works synergistically with titanium to enhance resistance to media such as chloride, sulfuric acid, and acetic acid, and its pitting corrosion resistance is better than that of ordinary 316 stainless steel.

(2) In a chloride ion environment (such as seawater), its crevice corrosion rate is reduced by more than 40%.

3. High temperature stability

Titanium stabilizes the austenite structure, so that the material still maintains good mechanical properties at 1200-1300℃, and the high temperature oxidation rate is reduced by about 30% compared with 316.

4. Mechanical and processing properties

(1) Tensile strength 515-690MPa, elongation ≥40%, with both high strength and toughness.

(2) Supports cold rolling (0.3-3mm), hot rolling (3-30mm) and welding processes, but welding parameters need to be controlled to retain the stabilizing effect of titanium.

II. Main application areas

1. Chemical equipment

Used for manufacturing sulfuric acid/phosphoric acid reactors, acetic acid storage tanks, urea synthesis towers, etc., resistant to strong acid corrosion and high temperature and high pressure environments.

2. Marine engineering

Applicable to seawater desalination equipment, offshore platform bolts, ship pipelines, etc., with a salt spray corrosion resistance life of 1.5 times that of ordinary 316.

3. Energy and medical

(1) Nuclear power plant steam generators, heat exchanger tube sheets, resistant to radiation and high temperature water corrosion.

(2) Surgical instruments, implants (such as orthopedic screws), meeting biocompatibility standards.

4. Food Industry
Brewing equipment and dairy processing lines offer smooth surfaces and no risk of heavy metal precipitation.

III. Summary

With titanium as its core innovation, 316Ti stainless steel plate excels in high-temperature corrosion resistance, weld stability, and long life, making it an ideal material for demanding working conditions, particularly in the chemical and marine industries, where safety requirements are paramount.
