製品の説明

254 SMO Stainless Steel Plate

Alloy 254 SMO is a premium super austenitic stainless steel plate with low carbon content, alloyed with molybdenum and nitrogen. This high-performance material offers exceptional resistance to pitting, crevice corrosion, stress corrosion cracking, and corrosion fatigue. With strength nearly double that of standard 300 series stainless steel, 254 SMO also provides high ductility and impact strength, making it ideal for demanding industrial applications.

Key Applications

Petroleum production equipment
Saltwater and seawater handling systems
Food and chemical processing equipment
Pulp mill bleach systems
Flue gas desulphurization scrubbers
Tall oil distillation columns
Offshore oil & gas production equipment
Desalination equipment

Corrosion Resistance

254 SMO stainless steel demonstrates excellent resistance to pitting and crevice corrosion due to its high chromium, molybdenum, and nitrogen content. The very low carbon content minimizes risk of carbide precipitation during heating. This alloy maintains exceptional performance in chloride-containing environments, including seawater, making it suitable for prolonged exposure without suffering from crevice corrosion.

Industry Applications

Ocean: Marine structures, seawater desalination, marine aquaculture, seawater heat exchange
Environmental Protection: Flue gas desulfurization, wastewater treatment
Energy: Nuclear power generation, coal utilization, wave power generation
