UGI® 316Ti is a titanium stabilised stainless steel with molybdenium added similar to UGI® 4571. The difference bet-ween the two grades lies in the titanium content which is superior in UGI® 316Ti than in UGI® 4571, which enhances its resistance to intergranular corrosion at high temperature (350°C - 850°C). Indeed, stabilisation rules of 1.4571 according to EN 10088-3 imposes Ti ≥ 5XC when 316Ti one’s according to ASTM A240 and A182 imposes Ti > 5x(C+N).

Non-magnetic in annealed condition.

Slight magnetism is produced by cold-working operations.

Technological properties

Application areas

  • Mechanical ans chemical industries
  • Oil and gas industries
  • Parts for boilers and incinerators

  • Corrosion properties

  • in natural environments: Water, rural and urban atmospheres, or industrial atmospheres and in the presence of moderate concentrations of chlorides and acids
  • in food processing and agricultural environments
  • in numerous acid (sulphuric, phosphoric and organic) and chloride chemical environments, un-der certain temperature and concentration conditions.

    UGI® 316Ti is resistant to inter-granular corrosion in the same way as UGI® 4571. Remark: The corrosion resistance of a stainless steel depends on many factors related to the composition of the corrosive atmosphere (chloride concentration, presence or absence of oxidising agents, temperature, pH, agitation or no agitation, and so on), as well as to the preparation of the material (surfaces free from metal particles, surface finish, such as hardening, polishing, and so on). Precautionary measures should be taken for certain tests such as the saline mist test (ISO 9227): for example marking labels (that might cause corro-sion run-outs and reduce the test resistance time) should not be used on the sample. Taking into account all theses precaution, UGI® 316Ti can withstand saline mist test (ISO9227) above 1000 h without any occurrence of red rust spots.

    The table below illustrates a performance scale (with three levels: good/average/excellent) in different environments:

    Nitric acidGood
    Phosphoric acidAverage
    Sulphuric acidAverage
    Acetic acidGood
    Sodium carbonateAverage
    NaCl (Saline mist)Good
    Sea waterAverage

  • General machinability

    UGI® 316Ti offers good machining performance as a result of the optimization of the inclusion population. This expands tool life, good chip breakability and good surface finish.

    Heat Treatment

    The annealing treatment that gives UGI® 316Ti its lowest properties includes heating to 1020°C - 1120°C, followed by rapid air or water cooling.

    Hot forming

    Forging : Heating temperature: 1150 - 1200°C . Forging temperature: between 1200°C and 950°C. Air cooling (or water cooling if deformation is not a problem).

    UGI® 316Ti can be MIG or TIG welded, with or without filler material, using laser or resistance welding techniques.

    When using filler wire, we recommend using ER318 (Nb stabilised). For cold applications, ER316LSi wire can also be used.

    To minimize thermal cracking problems, tight control over welding parameters is required. To do this, always ensure when using arc welding that the linear welding power is limited.
