🔹What is X2CrNiMo17-12-2 stainless steel round tubing?
X2CrNiMo17-12-2 (1.4404) is a low-carbon, austenitic stainless steel known as AISI 316L. It offers excellent corrosion resistance, especially in chloride-bearing, marine, and chemical environments. This material is commonly used in, pharmaceuticals, and food processing due to its high strength and, when welded, resistance to intergranular corrosion.

Advantages of X2CrNiMo17-12-2 stainless steel seamless tubing
🔹Superior Corrosion Resistance: 1.4404 stainless steel pipes have a carbon content of ≤0.03% and a PREN value of ≥32. In high chloride ion and weak acid environments, the corrosion rate is ≤0.002 mm/year. Its resistance to pitting and intergranular corrosion far surpasses that of ordinary 304 stainless steel, making it particularly suitable for demanding applications such as marine engineering and chemical fluid transportation.
🔹Precision Manufacturing: The outer diameter tolerance of the pipes is controlled within ±0.02mm, and the wall thickness tolerance is ±0.01mm. The inner wall is smooth and free of impurities (roughness Ra≤0.8μm), ensuring efficient and clean fluid transmission, meeting the standards for high-cleanliness applications in biopharmaceuticals and semiconductors.
🔹Full Compliance Certification: Manufactured in strict accordance with international standards such as EN 10216-5 and ASTM A213. Each batch comes with an EN 10204 3.1 material certificate and a third-party non-destructive testing report. It supports interchangeability with equivalent materials such as TP316L, meeting the compliance requirements of global projects.
🔹Flexible Delivery Capabilities: We can supply pipes with outer diameters from 6-219mm and wall thicknesses from 0.5-12mm. Standard sizes are available for quick delivery within 3-7 days, while customized sizes are produced within 10-15 business days. Packaging uses moisture-proof film and wooden pallets, supporting global sea, land, and air transportation to ensure the safe delivery of products.
