Properties of Stainless Steel Forgings
Stainless steel forgings are composed of a ferrous
alloy characterized by a stainless quality brought about
by its protective oxide layer that helps the material resist corrosion.
All stainless steel grades contain at least 10.5% chromium. Depending
on the grade selected, stainless steel forgings resist crevice corrosion,
stress cracking, pitting, heat deformation, and much more. There
are four main types of stainless steel duplex, austenitic,
martensitic, and ferritic.
Combining ferrite and austenite, duplex stainless
steel forgings tend to contain higher amounts of chromium and lower
amounts of nickel. With a high strength, duplex forgings resist
chloride stress corrosion, crevice corrosion, and pitting.
Austenitic Stainless Steel Forgings
This type of metal accounts for about 70% of
stainless steel used today. A typical alloy containing about 18%
chromium and 8% nickel, austenitic stainless steel forgings are
neither magnetic nor hardenable by heat treatment but exhibit high
levels of corrosion and heat resistance.
Ferritic Stainless Steel Forgings
Containing anywhere between 10.5% and 27% chromium,
ferritic stainless steel forgings are extremely corrosion resistant.
Ferritic stainless steel, however, is not as durable as other types
nor is it hardenable by heat treatment.
Martensitic Stainless Steel Forgings
Martensite contains a higher level of carbon
compared to other types of stainless steels, which makes it magnetic
and less resistant to corrosion and oxidation. Martensitic stainless
steel forgings, however, exhibit good ductility as well as high
strength and are hardenable by heat treatment.
