Why is molybdenum used in stainless steel?
Molybdenum adds corrosion resistance and high temperature strength. Molybdenum primarily increases the corrosion resistance of stainless steels (see Grades and Properties). As a large atom, molybdenum increases the elevated temperature strength of stainless steels through solid solution hardening.
What is Mo in steel?
Chromium molybdenum steel – frequently shortened to chrome moly – is a kind of low alloy steel used in a number of applications and industries. As the name suggests, the two key alloying elements are molybdenum (Mo) and chromium (Cr).

What kind of stainless steel is 6 Mo?
6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength compared with conventional austenitic stainless steels such as 316L. The alloy can provide excellent resistance…
What are the properties of ssc-6mo stainless steel?
General Properties SSC-6MO (UNS N08367) is a superaustenitic 6% molybdenum alloy that exhibits far greater resistance to chloride pitting, crevice corrosion and stress-corrosion cracking than the standard 300 series and standard duplex stainless steels.
How does the mechanical properties of a material affect it?
Database The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails.
What are the thermal and mechanical properties of molybdenum?
The mechanical properties of molybdenum are tabulated below. The thermal properties of molybdenum are tabulated below. The following are the application areas of molybdenum: As an alloying agent to provide hardness and toughness to quenched/tempered steels, and to improve the strength of steels at high temperatures
