The chemical composition and mechanical properties of ASTM A312 TP316L stainless steel pipes are as follows:
Chemical composition (%)
table
Element content
Carbon (C) ≤ 0.030
Silicon (Si) ≤ 1.00
Manganese (Mn) ≤ 2.00
Phosphorus (P) ≤ 0.045
Sulfur (S) ≤ 0.030
Chromium (Cr) 16.00-18.00
Nickel (Ni) 10.00-14.00
Molybdenum (Mo) 2.00-3.00
Note: TP316L is an ultra-low carbon stainless steel with a carbon content controlled at ≤ 0.03%, effectively reducing carbide precipitation during welding and improving resistance to intergranular corrosion.
