We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Stainless Steel 316 and 316L are both high-performance austenitic alloys, containing around 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. Notably, 316L has a lower carbon content (less than 0.035%), which enhances its resistance to intergranular corrosion, particularly after welding. The electropolishing process further improves these steel grades by eliminating surface imperfections and burrs through an electrochemical method, resulting in a shiny, smooth finish and a stronger passive layer. This process significantly enhances corrosion resistance, cleanability, and durability.
