TP316L Tp347 Steel Pipe High tensile strength For Chemical Industry
Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide
precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm).
There is commonly no appreciable price difference between 316 and 316L stainless steel.
TP316L seamless stainless steel pipe characteristics:
- Higher creep resistance
- Excellent formability.
- Rupture and tensile strength at high temperatures
- Corrosion and pitting resistance
