254SMO supporting welding materials:
ERNiCrMo-3 welding wire, ENiCrMo-3 covered electrode.
Main components of 254SMO:
254SMo contains carbon (C)≤0.02, manganese (Mn)≤ 1.00, nickel (Ni) ≤ 17.5 ~ 18.5, silicon (Si)≤0.8 and phosphorus (P)≤0.03.
Because of its high molybdenum content, it has extremely high pitting corrosion resistance and crevice corrosion resistance. This brand of stainless steel is developed for use in halide-containing environments, such as seawater. 254SMO also has good uniform corrosion resistance. Especially in acids containing halides, this steel is superior to ordinary stainless steel. Its c contains
Because this special stainless steel is a high alloy material, the manufacturing process is quite complicated. Generally speaking, people can only rely on traditional processes to manufacture this special stainless steel, such as casting, forging, rolling and so on.
254SMO corresponding brand:
UNS S3 1254, Germany /EN 1.4547, 254smo, f44,00cr20ni18mo6cun.
254SMO standard:
TM A240、ASME SA-240、B3 12/B269、A276
Physical characteristics of 254SMO:
Density: 8.24g/cm3, melting point: 1320- 1390℃, magnetism: none.
Mechanical properties of 254SMO:
Tensile strength: σb≥650Mpa, yield strength σb≥3 10Mpa, elongation: δ≥40%, hardness: 182-223(HB).
Corrosion resistance of 254SMO:
It is a super austenitic stainless steel with high corrosion resistance, which is developed for halide and acidic environment and widely used in harsh working conditions such as high concentration chloride ion medium and seawater. In various industrial occasions of acidic medium, especially in acid containing halide, 254SMO is far superior to other stainless steels, and can be comparable to Hastelloy and titanium in some cases. The low carbon content and high molybdenum content make it have good pitting corrosion resistance, crevice corrosion resistance and excellent intergranular corrosion resistance. It is a kind of stainless steel with high cost performance, which is widely used in chemical industry, desulfurization and environmental protection at home and abroad.
