The following desk exhibits mechanical properties of stainless-steel grade 254 SMO™. The bodily properties of stainless-steel grade 254 SMO™ are tabulated under. The excessive nitrogen content material additionally improves pitting resistance. Sandvik 254 SMO/ESR is, subsequently, a suitable materials for use in, for instance, seawater.

Alloy 254 SMO is a very high finish, molybdenum and nitrogen alloyed tremendous austenitic stainless steel with low carbon content. It demonstrates excellent resistance to pitting, crevice corrosion stress cracking, and corrosion fatigue uniform corrosion. Alloy 254 SMO is substantially stronger than the frequent austenitic grades, with energy practically twice that of 300 sequence stainless-steel. It can also be characterised by excessive ductility and impact energy. In some purposes it has even been discovered to be a more economical substitute for high nickel and titanium alloys.

Moreover, the addition of copper to those grades develops resistance to sulphuric acid and different lowering brokers in both aggressive and delicate situations. The corrosion resistance of grade 904L is intermediate between super austenitic grades, with 6% molybdenum content material, and commonplace 316L austenitic grades. Grade 904L is much less resistant to nitric acid than grades 304L and 310L, that are freed from molybdenum. This steel grade must be resolution treated following chilly working, to realize most stress corrosion cracking resistance under critical environments. Rolex calls 904L stainless-steel a “corrosion-resistant superalloy.” 904L differs from 316L because of further Chromium, Molybdenum, Nickel, and Copper that offers it improved resistance to acids.

The tables below give the outcomes of two accelerated tests, exhibiting that Sandvik 254 SMO has excellent resistance to SCC. Ordinary austenitic steels of the ASTM TP304 and TP316 sort are susceptible to stress corrosion cracking (SCC) in chloride-containing solutions at temperatures exceeding about 60°C (one hundred forty°F). For the austenitic steels, resistance to SCC will increase with greater nickel and molybdenum contents. The tables below show the outcomes of two accelerated checks, clearly demonstrating that Sandvik 254 SMO has an excellent resistance to SCC. Duplex stainless steels are normally chosen for their excessive mechanical properties and good to very excessive corrosion resistance (particularly to emphasize corrosion cracking).

In frequent with all absolutely austenitic stainless steels, Sandvik 254 SMO has low thermal conductivity and high thermal growth. Sandvik 254 SMO is a high alloyed austenitic stainless-steel and thus tougher inserts in metal chopping are needed than is the case for decrease alloyed austenitic grades. When machining Sandvik 254 SMO significantly decrease chopping speeds are recommended in comparison with the grades Sanmac 304/304L and Sanmac 316/316L, which have improved machinability. Grade 904L stainless steels supply good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above four hundred°C.

Grade 904L is non-magnetic, and provides wonderful formability, toughness and weldability. Stainless metal grade 254 SMO™ is a very excessive finish austenitic chrome steel. Grade 904L stainless steels have glorious resistance to heat seawater and chloride attack. The high resistance of grade 904L against stress corrosion cracking is as a result of presence of excessive amounts of nickel in its composition.

At High Temperatures

Grade 904L electrodes and rods are used for welding grade 904L steels in accordance with AS 1554.6. Grade 904L stainless steels could be solution warmth-treated at 1090 to 1175°C, following by rapid cooling. Thermal therapy is suitable for hardening these grades. In common with all fully austenitic stainless steels, Sandvik 254 SMO/ESR has low thermal conductivity and excessive thermal expansion.
