This alloy, a subtype of the stainless steel grade 316, is crucial to applications involving structures. Austenitic alloy stainless steel 316ti pipe in both seamless and welded constructions comes under the specification like ASTM A312. These pipes are useful in applications that require resistance to high temperatures and general corrosion. Stainless Steel 316ti Seamless Pipe and grade 316 have comparable corrosion resistance characteristics. SS 316Ti Chemical Composition is listed below. Although the alloy 316TI offers improved weldability and demonstrates outstanding performance at high temperatures because titanium has been added to it.
General Properties of SS 316 Ti Grade
When chromium grain boundary precipitates start to form between a temperature of 900 °F and roughly 1500 °F, sensitization has occurred. In such circumstances, it is not advisable to utilize any type of ordinary steel, not even stainless steel 304. SS 316ti Welded Pipe is the best material to use in these circumstances. Since it resists corrosion better than earlier alloys. The tensile properties of stainless steel pipe type 316ti must comply with the required tensile and yield strengths, per ASTM A312 specification.
The ASTM A312 TP316ti is subjectable to mechanical testing like a transverse test or a longitudinal tension test coupled with a flattening test. Additionally, manufacturers assess the grain size of the ASME SA 312 TP316ti pipes and subject them to a weld degradation test. The SS 316ti ERW Pipe must undergo testing on an individual basis, such as a hydrostatic test or a non-destructive electric test.

Applications
Austenite is stabilized by the titanium addition in the stainless steel 316Ti seamless pipe alloy. The alloy already possesses characteristics that directly link to strong resistance to corrosion because it is a molybdenum-bearing grade. The ASTM A312 Type 316Ti ERW Pipe possesses unbeatable corrosion resistance capabilities against acids utilized in the chemical processing industries, such as acetic acid, formic acid, hydrochloric acid, sulfuric acid, and tartaric acid. The corrosion resistance characteristics of SS 316Ti Welded Pipe are ideally useful for applications that may contain solutions of both acid sulphates and alkaline chlorides in addition to such potent acids.
