The **chemical composition** of these alloys showcases their impressive performance in harsh environments. Grade 316 contains up to 0.08% carbon, while 316L is a low-carbon alternative (≤ 0.03%) designed to reduce carbide precipitation and improve weldability. Both grades feature 16–18% chromium, 2–3% molybdenum, and 10–14% nickel. When it comes to **mechanical properties**, these pipes are built to last: Grade 316 boasts a minimum tensile strength of around 515 MPa and a yield strength of about 205 MPa, while 316L has slightly lower values (approximately 485 MPa tensile and 170 MPa yield). Both grades offer an elongation of around 40% and a hardness of up to 95 HRB. Key physical properties include a density of roughly 8,000 kg/m³, an elastic modulus of about 193 GPa, and a thermal expansion coefficient close to 15.9 µm/m·°C.
Stainless Steel 316 and 316L EFW Pipes are widely used in various industries due to their corrosion resistance and excellent durability. Commonly found in chemical plants, oil and gas facilities, and marine environments, where severe exposure conditions are common These pipes are also used in pharmaceuticals and food in which products are clean and safe. Additionally, they are ideal for architectural applications, such as handrails and support structures due to their aesthetics and resistance to extreme weather conditions.
