Stainless Steel ASTM A312 TP316Ti Pipe

Tubos India is one of the large manufacturers for high quality 316Ti Stainless steel Pipes. 316Ti Alloy pipes is essentially a standard carbon 316 type with titanium stabilisation and is similar in principle to the titanium stabilisation of the 304 type to produce 321 type. The addition of titanium in the 316Ti Stainless Steel Seamless Pipes is made to reduce the risk of inter – granular corrosion (IC) heating in the temperature range from 425 Degree C – 815 Degree C. When austenitic SS 316Ti Welded Pipes are subject to prolonged heating in the temperature range from 425 Degree C to 815 Degree C, the carbon in the steel diffuses to the grain boundaries and precipitates chromium carbide. This process removes chromium from the solid solution in the Stainless Steel 316Ti EFW Pipes.

The grain boundaries in SS 316Ti ERW Pipes become prone to preferential attack on subsequent exposure to a corrosive environment, where this type of corrosion is known as inter – granular corrosion (IC). The addition of titanium in these 316Ti SS Round Pipes reduces the risk of IC since titanium carbo – nitrides that are formed in preference to chromium carbides which have effect of maintaining the correct chromium distribution throughout the structure of the steel.
