Established in 2014, OES Metal has evolved into a global leader in the stainless steel manufacturing sector. Headquartered in the industrial hub of Wuxi, Jiangsu, our facility spans 5,000 square meters, housing cutting-edge platform processing equipment designed for precision manufacturing, automated cutting, and secure packaging.
With a dedicated team of over 100 professionals, we don't just supply metal; we provide engineering solutions. From ASTM A312 seamless pipes to specialized bright annealed tubing, our quality control services ensure every millimeter meets international technical standards.
The global demand for Tube 316 is witnessing a paradigm shift driven by the expansion of the "Blue Economy" (marine exploration) and the rapid growth of the biopharmaceutical sector. As an austenitic chromium-nickel stainless steel, Grade 316 offers a unique combination of weldability and mechanical strength that Grade 304 cannot match in saline or corrosive chemical environments.
316L tubing is becoming the standard for hydrogen transport systems due to its resistance to hydrogen embrittlement at high pressures.
Industry 4.0 integration allows us to provide real-time tracking and precision tolerances up to +/- 0.05mm for high-end instruments.
The rise of biotech requires Electropolished (EP) 316L tubes with ultra-low surface roughness to prevent bacterial growth.
As a leading China Tube 316 manufacturer, OES Metal leverages the world's most complete stainless steel supply chain. We utilize high-purity raw materials from Tier-1 mills (like TISCO and BAOSTEEL) to ensure our 316/316L products have the precise chemical composition required for corrosion resistance.
In regions like the Gulf countries (UAE, Saudi Arabia), our 316 pipes are used extensively in desalination plants where saltwater corrosion is the primary challenge. In South America, mining operations rely on our heavy-wall 316 tubes for slurry transport in acidic environments.
Our "Smart Factory" initiative incorporates AI-driven quality inspection, ensuring that weld seams in our 321 and 316 welded tubing are 100% X-ray tested for integrity.
From ASTM A312 for general service to A213 for heat exchangers. Our seamless 316 pipes are cold-drawn and annealed to perfection.
Mirror finish, brushed, or 2B finish. Available in 4x8 sizes or custom slitting coils for automated manufacturing lines.
Hexagon, round, and square bars. Ideal for machining valves, fittings, and fasteners for the oil and gas industry.
Marine & Offshore: In the North Sea or Southeast Asian waters, 316 tubing is the standard for hydraulic lines and instrumentation on oil rigs. Its resistance to pitting in salt spray is unmatched.
Food & Beverage: Throughout Europe and North America, our bright annealed 316 tubes are used in milk processing and brewery equipment. The smooth internal surface prevents protein buildup and ensures easy cleaning (CIP).
Chemical Processing: Handling sulfuric or phosphoric acids requires the molybdenum-enhanced structure of Grade 316. Our factory provides specialized passivation treatments to further enhance the protective oxide layer.
The difference between 316 and 316L is the carbon content. 316L (Low Carbon) is preferred for welded applications because it prevents "carbide precipitation" during the welding process, maintaining corrosion resistance at the joints. At OES Metal, we analyze every heat to ensure carbon levels are below 0.03% for all 316L orders.
