254 SMO(00Cr20Ni18Mo6CuN,S31254) is one kind of Austenitic stainless steel.Owing to its high content of Mo.It has obtained a high corrosion resistance and resistant materrial crevice corrosion performance.This type stainless steel is researched and developed in the condition where contains halides, such as the seawater, and also it has the perfect function of uniform corrosion resistance especially in the acid condition where contains halides. In conclusion, it is superior to other common stainless steels.
(C)≤0.02, (Mn)≤1.00, (Ni)17.5～18.5, (Si)≤0.8 (P)≤0.03, (S)≤0.01, (Cr)19.5～20.5, (Cu)0.5～1.0, (Mo)6.0～6.5
Standards：UNS S31254、DIN/EN 1.4547、ASTM A240、ASME SA-240
Physical characteristics：density：8.24g/cm3，melting point：1320-1390 ℃，magnetism：no
Mechanical capacity：strength of extension：σb≥650Mpa，yield strengthσb≥310Mpa：elongation：δ≥40%，rigidity：182-223（HB）
Corrosion resistance: It is a kind of highly good corrosion resistance austenitic stainless steel, and developed in the environment of the halide and acid, which is widely used in the severe environment such as the igh concentrations of chloride ion medium and seawater.
In various industrial places of the acidic medium , especially in the acid, containing halides, 254SMO is far better than any other stainless steel, in some cases it can be comparable with hastelloys steel and titanium.
Low carbon content and high molybdenum content make it obtain good corrosion resistance and resistant materrial crevice corrosion performance, excellent intergranular corrosion resistant ability, which is widely used in the filed of the chemical, desulfurization environmental protection etc as a cost-effective stainless steel at home and abroad.
