Plain
Steel
C-1008 |
Used
for dry applications and low temperature ovens. |
High Carbon
C-1040-1055 |
For dry atmospheres
and heavier loads where severe wear is expected in temperatures
ranging up to 1050 °F.
This provides greater strength and resistance to abrasion. |
| 1% Chrome |
The addition
of chrome provides greater strength and oxidation resistance which allows
this alloy to be used in
temperatures up to 1200 °F. |
| 3%
Chrome |
The addition
of chrome and silicon content increases oxidation resistance and permits
this alloy to be used in
temperatures up to 1300 °F. |
| Type
304 S.S. |
This alloy has
a greater oxidation resistance than type 430 s.s. but is subject to carbide
precipitation and embrittlement in the range of 500 °F - 1500 °F.
Most commonly used in chemical, food processing, and marine equipment.
This alloy is not suitable for high temperature applications. |
| Type
316 S.S. |
The addition
of molybdenum provides a higher corrosion resistance than type 304 s.s.
This alloy is resistant
to sulfuric and ditric acids, pitting from bromides, acetic and
phosphoric acids. |
| Type
347 S.S. |
Type 347 s.s.
is almost identical to type 304 s.s. except for the addition of columbium,
thus eliminating danger
of carbide precipitation that occurs from 800 °F - 1500 °F.
This alloy is much stronger
that type 304 s.s. and type 316 s.s. in the temperature range. |
| Type 321 S.S. |
Similar to type
304 s.s. but with a titanium stabilizer. It loses certain elements when
welded. |
| Type 309 S.S. |
Provides good
oxidation resistance up to 1700 °F, but is subject to carbide precipitationand
scaling in the temperature range of 800 °F - 1500 °F. |
| Type 310 S.S. |
At elevated
temperatures this alloy has greater strength and scale resistance than
type 309 s.s. Commonly used
for heat exchangers, furnace parts, combustion
chambers, gas turbine parts,
etc. |
| Type 314 S.S.
|
This alloy is
commonly used for high temperature belt applications such as copper
brazing and powdered metal
sintering. The high silicon content increases its resistance to oxidation
and carburization. This alloy is also subject to carbide precipitation
and embrittlement in the temperature range of 800 °F - 1500 °F. |
| Type 35/19 |
Recommended
for oxidizing atmospheres below 1900 °F under cycle heating conditions,
has good resistance to thermal shock, greater strength, and less elongation.
However, can suffer from excessive grain growth and internal fracture. |
| Type 35/19 CB |
Like type 35/19
but with columbium added as a stabilizing agent which prevents carbide
precipitation, resists carburizing and carbo-nitriding up to 1750 °F,
like type 35/19 can suffer from excessive grain growth. |
| Inconel 600
|
This alloy has
an excellent resistance to carburization, nitriding, and oxidization at
higher temperatures than type 314 s.s. and type 35/19 above 1800 °F.
An excellent alloy for nitriding because of its excellent resistance to
ammonia, nitrogen, and resistance to molten aluminum flux. |
| Inconel 601 |
With a higher
chrome content and addition of aluminum alloy. This gives additional
resistance to oxidation,
carburization, and sulfuric elements. |
| 80/20 CB
|
Recommended
for temperatures ranging from 1800 ° F - 2100 °F. This alloy has
an
excellent oxidization resistance
and high strength at elevated temperatures. The addition of columbium as
a stabilizing agent makes this alloy resistant to "green rot" at temperatures
between 1800 °F - 1900 °F. |
| Tophet F |
This alloy is
similar to 80/20 CB with the addition of aluminum. This improves resistance
to extremely high temperatures in oxidizing and reducing atmospheres. Subject
to embrittlement between 1000 °F - 1200 °F. |
| Trophet 30 |
With 30% chromium
and 70% nickel, it provides superior oxidation resistance at
temperatures as high as
2200 °F. |
