3. Mechanical properties, tensile strength, sigma b p 650 mpa, yield strength sigma 310 mpa or greater b:
elongation: delta p 40%, hardness: 182-223 (HB)
4. Corrosion resistance: is a highly corrosion resistant super austenitic stainless steel, in view of the halide
and acid environment and development, are widely used in high concentrations of chloride ions in the
medium, seawater for harsh working environment. In acidic medium of all kinds of industrial occasions,
especially in
acid containing halide, 254 smo is far better than the other stainless steel, some cases are comparable to
those obtained and hartz alloy, and titanium. Low carbon content and high molybdenum content, make it has
good resistance to pitting corrosion and crevice corrosion resistance, excellent resistance to intercrystalline
corrosion, stainless steel is a kind of high performance to price ratio, at home and abroad, chemical industry, environmental protection and other fields is widely used for desulphurization.
5. application fields
