ASTM A312 TP316 and TP316L are common materials for stainless steel pipes. This article will help you understand the differences between these two materials.
As the chemical composition table above, the main difference between ASTM A312 TP316 and 316L is the carbon content. 316L stainless steel is a low carbon version of 316 stainless steel, and the lower carbon content in 316L stainless steel can reduce harmful carbide precipitation caused by welding.
TP 316 (MPa)
From the above data, it can be seen that the mechanical properties of ASTM A312 TP316 are stronger in tensile strength and yield strength than TP316L .This is due to the different carbon (C) content, which is a strong austenite-forming element that can significantly increase the strength of stainless steel.
Corrosion Resistance: TP316 has excellent corrosion resistance and can resist the corrosion of chloride ions and oxidizing media.TP316L has better corrosion resistance on the basis of TP316.
Application Ranges: TP316 is widely used in petroleum, chemical, power, metallurgical, and hydraulic tube industries.Due to its higher corrosion resistance and high strength, TP316L has a wider range of applications and can be used in harsher environmental conditions.
From the above analysis, it is not difficult to notice that although ASTM A312 TP316 and TP316L are both stainless steel materials, there are many differences . Therefore, customers should choose the appropriate stainless steel material basing on the specific using environment to measure its advantages and performance better.
