Different materials for pipes require different considerations; for example, 316 and 316L – what are the things to keep in mind when using them, and what are the differences in their properties?
This post was last edited by HOULS71 on 2011-9-15 at 11:16, mainly due to concerns regarding high-temperature strength. Since the carbon content in SS316L is below 0.03%, it cannot meet the requirements for use in high-strength steels. However, due to its low carbon content, its resistance to intergranular corrosion is better than that of SS316. Please check this post: http://bbs.hcbbs.com/thread-344175-1-1.html
316L is a low-carbon austenitic stainless steel; due to its low carbon content, the likelihood of carbon precipitating at the grain boundaries under high-temperature conditions is relatively low, which gives it better resistance to intergranular corrosion at high temperatures compared to 316.
