It is characterized by ultra-low carbon content (\u22640.035%), supplemented with 2.0\u20133.0% molybdenum, which endows it with superior corrosion resistance, especially in chloride-rich environments. It is widely recognized as a &#8220;marine-grade&#8221; stainless steel pipe and is extensively used in industries with high corrosion resistance requirements.<\/p>\n\n<h5>Key Characteristics<\/h5>\n<ul>\n<li>Excellent Corrosion Resistance: Molybdenum addition significantly improves resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brine, and other chloride-containing media.<\/li>\n<li>Outstanding Intergranular Corrosion Resistance: Ultra-low carbon content effectively inhibits chromium carbide precipitation at grain boundaries during welding and high-temperature service, eliminating sensitization and ensuring corrosion stability of welded joints.<\/li>\n<li>Superior Weldability: Low carbon reduces weld decay risk; it can be welded by common methods (TIG, MIG, submerged arc welding) without post-weld heat treatment.<\/li>\n<li>Good Mechanical Properties: Maintains moderate tensile and yield strength at room and elevated temperatures, with excellent ductility and formability.<\/li>\n<li>Non-magnetic: Typically non-magnetic in the annealed state; slight magnetism may appear after cold working.<\/li>\n<li>Heat Resistance: Exhibits good oxidation resistance and creep strength at high temperatures (up to ~870\u00b0C).<\/li>\n<\/ul>\n<h5>Production &amp; Types<\/h5>\n<ul>\n<li>Manufacturing Processes: Seamless pipes via hot rolling, cold rolling, and cold drawing; welded pipes via ERW (electric resistance welding), LSAW (longitudinal submerged arc welding), etc.<\/li>\n<li>Product Forms: Seamless pipes, welded pipes, heavy cold-worked pipes; available with plain ends, beveled ends, or threaded ends.<\/li>\n<li>Surface Treatments: Pickling, passivation, bright annealing, mechanical polishing (Ra \u2264 0.8\u03bcm for hygienic applications).<\/li>\n<\/ul>\n<h5>Chemical Composition (wt%, ASTM A312\/ASME SA312)<\/h5>\n<table>\n<tbody>\n<tr>\n<td><strong><b>\u042d\u043b\u0435\u043c\u0435\u043d\u0442<\/b><\/strong><\/td>\n<td><strong><b>316L (S31603)<\/b><\/strong><\/td>\n<td><strong><b>316 (S31600, for comparison)<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td>\u0423\u0433\u043b\u0435\u0440\u043e\u0434 (C)<\/td>\n<td>\u22640.035<\/td>\n<td>\u22640.08<\/td>\n<\/tr>\n<tr>\n<td>\u041c\u0430\u0440\u0433\u0430\u043d\u0435\u0446 (Mn)<\/td>\n<td>\u22642.00<\/td>\n<td>\u22642.00<\/td>\n<\/tr>\n<tr>\n<td>\u041a\u0440\u0435\u043c\u043d\u0438\u0439 (Si)<\/td>\n<td>\u22641.00<\/td>\n<td>\u22641.00<\/td>\n<\/tr>\n<tr>\n<td>\u0424\u043e\u0441\u0444\u043e\u0440 (P)<\/td>\n<td>\u22640.045<\/td>\n<td>\u22640.045<\/td>\n<\/tr>\n<tr>\n<td>\u0421\u0435\u0440\u0430 (S)<\/td>\n<td>\u22640.030<\/td>\n<td>\u22640.030<\/td>\n<\/tr>\n<tr>\n<td>Chromium (Cr)<\/td>\n<td>16.0\u201318.0<\/td>\n<td>16.0\u201318.0<\/td>\n<\/tr>\n<tr>\n<td>Nickel (Ni)<\/td>\n<td>10.0\u201314.0<\/td>\n<td>10.0\u201314.0<\/td>\n<\/tr>\n<tr>\n<td>Molybdenum (Mo)<\/td>\n<td>2.0\u20133.0<\/td>\n<td>2.0\u20133.0<\/td>\n<\/tr>\n<tr>\n<td>Nitrogen (N)<\/td>\n<td>\u22640.10<\/td>\n<td>\u22640.10<\/td>\n<\/tr>\n<tr>\n<td>\u0416\u0435\u043b\u0435\u0437\u043e (Fe)<\/td>\n<td>\u0411\u0430\u043b\u0430\u043d\u0441<\/td>\n<td>\u0411\u0430\u043b\u0430\u043d\u0441<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h5>Dimensional Specifications &amp;
