316 Stainless is most
often selected for its ability to resist corrosive attack. In heavy
industrial maintenance applications however, it would be very unusual to
find an application where the problem was just limited to corrosion.
Often the failure of
shafting is the result of several influences: corrosion, twist, chatter,
stress, wear, flex, etc. The unique properties of Mar-10 resist failure
where any or all of those conditions exist.
When you consider that
Can be mushy to
Does not wear as well
Has much lower
strength levels (i.e. tensile)
Is harder to weld
Is susceptible to
stress corrosion cracking
May invite galling
Can cause premature
wear on the mechanical seals due to flex
In areas where types 410 and 416 Stainless have been utilized, Mar-10
should also be considered.
410 Stainless is most often selected
because it is hardenable and weldable,
but it is difficult to machine.
416 Stainless is most
often selected because it is hardenable and easy to machine, but
welding is not recommended.
Mar-10 provides greater
resistance to corrosion. Even 410 and 416 do not resist Atmospheric
Pitting as well as Mar-10. As delivered Mar-10 provides an unusual
degree of toughness, is easy to machine, and is weldable.
Consider the savings
with Mar-10 in not only the extended service life but also in the
replacement of three materials in inventory with just one.
