ASTM A312 321Ti Stainless Seamless Steel Pipe Polished Industry 100mm
321Ti Stainless Steel Pipe Specification
Stainless Steel 316Ti is most commonly for elevated temperature situations. This grade contains a small amount typically only 0.5% of titanium. the addition of titanium allows 316Ti to be protected from precipitation at high temperatures, even with prolonged exposure. 316Ti also contains an addition of molybdenum in its composition.the molybdenum serves as increased protection against corrosion .pitting from chloride solutions and offer higher creep, stress-rupture and tensile strength at elevated temperature. However, its high temperature resistance is also compounded by its titanium content, which allows 316Ti to be immune to precipitation at these temperatures. Additionally, the metal shows resistance to acids, such as sulfuric acids, hydrochloric acids, and acid sulfates.
321 Ti Seamless pipe Chemical Composition
| Element | 316Ti |
| Ni | 10.0-14.0 |
| C | 0.08max |
| Mn | 2.0max |
| P | 0.045max |
| S | 0.30max |

| Mo | 2.0-3.0 |
| Ti | 5x(C+N)-0.70 |
| N | 0.10MAX |
Advantage
1.The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation (precipitation) occurring.
2.Long service life of stainless steel pipe.
