Choosing Stainless Steel 316 and 316L ERW Pipes from Maria Pipes and Tubes guarantees excellent corrosion resistance, high strength, and durability. Designed for diverse industrial applications, it delivers reliable performance in tough environments while maintaining competitive pricing for cost-effective solutions.
When it comes to composition, **Stainless Steel 316** contains up to 0.08% carbon, while **316L** has a lower carbon content (≤ 0.035%), which helps reduce carbide precipitation and enhances weldability—making it less susceptible to sensitization and intergranular corrosion. Both grades are composed of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, which significantly boosts their resistance to chlorides and harsh environments. Mechanically, these grades perform robustly, with tensile strength around 515 MPa, yield strength near 205 MPa (with 316L being slightly lower), elongation of at least 35%, and hardness reaching up to Rockwell B 95. Their material characteristics—density (~8,000 kg/m³), elastic modulus (≈193 GPa), and thermal expansion (~15.9 μm/m·°C)—further solidify their suitability for various applications.
