Key features of ss904L plate
stainless steel 904l High chromium and high molybdenum composition
The typical composition contains about 20% chromium (Cr) and 4.5% molybdenum (Mo). Chromium forms a dense passive film to resist oxidizing environment, while molybdenum significantly enhances the pitting and crevice corrosion resistance in reducing acidic media (especially chloride ion environment). Its pitting resistance equivalent value (PREN = %Cr + 3.3x%Mo + 16x%N) is usually more than 33, far exceeding 316L (about 24) and even 317L (about 29).
uns n08904 sheet Ultra-low carbon and nitrogen synergy, stable and reliable
The extremely low carbon content (<0.02%) effectively avoids the precipitation of chromium carbides between grains during welding and high-temperature service, ensuring the corrosion resistance of the welding area and heat-affected zone. The appropriate nitrogen content (0.1-0.2%) not only stabilizes the austenite structure, but also further improves the strength and corrosion resistance (especially pitting/crevice corrosion resistance), and delays the formation of harmful intermetallic phases.
s904l steel plate Nickel-copper content
High nickel content (~24%) ensures the stability of the austenitic structure under harsh conditions and provides excellent resistance to stress corrosion cracking (SCC), especially in chloride ion environments. The addition of copper (~1.5%) significantly enhances the corrosion resistance of the material in reducing acids such as sulfuric acid and phosphoric acid, broadening its application range.
n08904 steel plate Strength and toughness
Compared with ordinary austenitic stainless steel (such as 304L, 316L), S904L has higher yield strength and tensile strength, while maintaining good plasticity and toughness, meeting the mechanical requirements of pressure-bearing equipment and structural parts.
ss904l processing and weldability
It retains the good hot and cold forming ability and weldability of austenitic stainless steel. Conventional stainless steel welding methods (such as TIG, MIG, SMAW, SAW) can be used. Usually, heat treatment is not required after welding, but matching high-alloy welding materials (such as 625 alloy) must be used.
Application of 904L stainless steel plate
Oil and gas: submarine pipelines, downhole tools for acid gas wells.
Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.
Nuclear industry: containers and pipelines for nuclear waste treatment systems.
Marine engineering: seawater desalination devices, heat exchangers.
Environmental protection: key components of flue gas desulfurization (FGD) systems.
