Sihe Steel
Premium ASTM & AISI standard 316/316L capillary and control line tubing supplied directly to Bosnian industries.
Comprehensive metallurgical analysis for design engineers, procurement specialists, and industrial decision-makers in Canton Sarajevo and the wider Western Balkans region.
Grade 316 (UNS S31600 / EN 1.4401) and its low-carbon variant 316L (UNS S31603 / EN 1.4404) are distinguished by the integration of 2.0% to 3.0% Molybdenum (Mo). This addition elevates the Pitting Resistance Equivalent Number (PREN $\ge 23.1$), offering superior resistance against chloride ion pitting and crevice corrosion compared to standard 304 stainless steel.
Our production line utilizes world-class continuous hydrogen bright annealing at temperatures exceeding 1050°C. This stress-relieving heat treatment guarantees an oxide-free, mirror-bright surface finish both internally (ID Ra $\le 0.4 \mu m$) and externally, minimizing friction and preventing particulate entrapment in chromatographic and analytical applications.
With carbon content controlled to $\le 0.03\%$ in 316L, chromium carbide precipitation at grain boundaries during welding or operational exposure (450°C to 850°C) is completely suppressed. This makes our capillary tubes the ideal choice for high-pressure fluid power, chemical processing plants, and district heating sensors across Sarajevo.

Navigating supply chain dynamics, regional logistics corridors, and localized manufacturing demands in Bosnia and Herzegovina.
Sarajevo, as the economic core of Bosnia and Herzegovina, is experiencing significant modernization across automotive component manufacturing, HVAC systems integration, medical device assembly, and municipal infrastructure. The region's proximity to the European Union market requires rapid procurement of high-precision stainless steel seamless coiled tubing and capillary pipes that strictly adhere to ASTM A269, ASTM A632, and EN 10216-5 specifications.
Local Sarajevo fabricators and original equipment manufacturers (OEMs) often face high markups from European stockists. Sourcing directly from certified Chinese manufacturers such as Liaocheng Sihe Stainless Steel Material Co., Ltd. bridge this cost gap while maintaining 100% compliance with EU material test certificates (EN 10204 3.1).
