Sanhe Steel:Searching for a 'sea stabilizing needle' in the fluctuations of the Shipbuilding Steel Plate supply chain

The fluctuation of global shipping rates and the long-term nature of shipbuilding orders pose higher challenges to the stability of upstream raw material supply. As a "hidden champion" in the domestic shipbuilding steel industry, Sanhe Steel has recently optimized its inventory management system and direct supply channels, successfully providing key Shipbuilding Steel Plate resource guarantees for several overseas Very Large Crude Carrier (VLCC) projects.

Unlike traditional traders who simply match transactions, Sanhe Steel is more like a "material steward". Against the backdrop of current shipyards' demand to shorten the spot cycle to "calculated on a weekly basis", Sanhe has achieved immediate response to the core specification of Shipbuilding Steel Plate by relying on its strategic warehousing near the port.

Nowadays, ship owners not only value price, but also value the 'history' of steel plates, "said a procurement manager responsible for international business. Every Shipbuilding Steel Plate supplied by Sanhe Steel has traceable original data from the classification society, which is undoubtedly a hard card in the increasingly compliant high-end offshore market. By deeply integrating the production capacity of top domestic steel mills, Sanhe is reshaping the path for small and medium-sized shipyards to obtain high-performance materials.

From cryogenic environment to high salt corrosion: the technological breakthrough path of Sanhe Steel's high-grade Shipbuilding Steel Plate

Recently, Sanhe Steel officially delivered the Shipbuilding Steel Plate for a certain polar waterway support ship. This special steel grade not only needs to maintain excellent impact power at extreme low temperatures of -40 ° C, but also needs to pass rigorous Z-directional performance testing (Z35 level) to prevent delamination and cracking of thick plates during heavy-duty welding processes.

In shipbuilding engineering, welding defects are the main culprit leading to a significant increase in costs. The Sanhe Steel technology team has fine tuned the carbon equivalent index of the Shipbuilding Steel Plate they supply through in-depth communication with the shipyard's process department. Experimental results have shown that the performance of this batch of steel is extremely stable under manual welding and submerged arc automatic welding, and the performance degradation in the heat affected zone is much lower than the industry average.

In addition, Sanhe Steel's machining center has also upgraded the pre-treatment of this batch of Shipbuilding Steel Plates. After using the ball shot blasting process to achieve the Sa2.5 purification standard, the modified epoxy workshop primer is immediately sprayed to ensure that the steel plate does not rust back during the months long shipyard closure period. This delivery model that starts from details not only reduces the pressure of secondary rust removal for shipyards, but also significantly improves the overall adhesion of ship hull coating.
