Originally, stainless steel alloy 316 does not contain titanium in its chemistry. However, the addition of titanium in the Stainless Steel 316Ti Seamless Pipe alloy has a stabilizing effect on austenite. As a molybdenum-bearing grade, the alloy already has properties associated with high resistance to corrosion. Yet, the addition of titanium in the ASME SA 312 Grade 316Ti Square Pipe takes its yield strength to a higher level. Moreover, the alloy benefits from titanium as it can withstand high temperature settings as well.
Specifically, specification ASTM A312 is used in the construction of several austenitic stainless steel alloys, including UNS S31703 schedule 40 pipe. The specification is essentially suited for pipes that are operational at higher temperatures, and those applications that demand the DIN 1.4571 Rectangular Pipe to be used for resistance to general corrosion. This molybdenum containing alloy demonstrates resistance to several compounds and various solutions.
And the corrosion resistance properties of the ASTM A312 Type 316Ti ERW Pipe against acids used in chemical processing industries such as acetic acid, formic acid, hydrochloric acid, sulfuric acid, and tartaric acid, are insurmountable. Along with such strong acids, the corrosion resistance properties of SS 316Ti Welded Pipe are well suited to applications that may contain solutions of both, acid sulfates, and alkaline chlorides.
