Send Inquiry NowBusan, the maritime capital of South Korea, hosts one of the largest container ports globally and acts as a pivotal hub for shipbuilding, marine structures, and heavy machinery fabrication. The regional marine environment imposes extreme corrosion pressures on structural and fluid transport components. In salt-laden coastal atmospheres and deepwater marine setups, general-grade steels fail rapidly due to localized chloride attack.
This chemical susceptibility demands high-performance alloy piping. The implementation of 316L (UNS S31603) stainless steel is non-negotiable for modern engineering operations here. Featuring a robust chemical mix with critical molybdenum additions, our 316L welded pipes provide an optimal balance of structural strength, weldability, and resistance to pitting and crevice corrosion.
Whether serving as hydraulic system tubing on ultra-large container ships manufactured near Geoje and Busan, or as process piping in coastal chemical complexes, our pipes deliver the exact technical specifications necessary to prevent weld decay and preserve system integrity.
To assist procurement engineers in validating design tolerances, the table below outlines the differences in chemical composition between 316L and other high-performance alloys.
| Alloy Grade | UNS Designator | Nickel (Ni) % | Chromium (Cr) % | Molybdenum (Mo) % | Carbon (C) % Max | Key Properties & Best Applications |
|---|---|---|---|---|---|---|
| 304L | UNS S30403 | 8.0 - 12.0 | 18.0 - 20.0 | - | 0.030 | Standard sanitary application, mild atmospheric corrosion resistance. |
| 316L | UNS S31603 | 10.0 - 14.0 | 16.0 - 18.0 | 2.0 - 3.0 | 0.030 | Chloride resistance, maritime structure piping, pharmaceutical applications. |
| Duplex 2205 | UNS S32205 | 4.5 - 6.5 | 22.0 - 23.0 | 3.0 - 3.5 | 0.030 | High yield strength, supreme pitting resistance in offshore deepwater oil extraction. |
| Super Duplex 2507 | UNS S32750 | 6.0 - 8.0 | 24.0 - 26.0 | 3.0 - 5.0 | 0.030 | Exceptional resistance to acidic chloride media, heavy chemical industry piping. |
| Alloy 825 | UNS N08825 | 38.0 - 46.0 | 19.5 - 23.5 | 2.5 - 3.5 | 0.050 | High nickel content prevents stress corrosion cracking under high-pressure geothermal conditions. |

Our 316L welded and seamless pipes are engineered for the following industrial environments.
Explore our wider product line, including high-temperature alloys, capillary sizing, and long-run coils.
Understanding the pricing structure of 316L stainless steel welded pipes requires analyzing key alloy market drivers. Unlike standard carbon steel, 316L contains 2% to 3% molybdenum. The price index of molybdenum, alongside LME nickel market fluctuations, represents a large portion of the material's cost basis.
For engineering procurement contractors (EPCs) based in Busan, sourcing from our high-capacity Chinese mills offers distinct structural cost advantages. By maintaining massive raw material reserves and utilizing automated weld lines, we mitigate market volatility.
Furthermore, the proximity between our logistics centers and Busan Port enables fast, low-cost transport. Standard sea freight from our shipping terminals to Busan takes only 1 to 3 days, providing a reliable alternative to local distributors.
