For service up to 800oF where corrosion and oxidation are not a factor.
Low Alloy ASTM/
ASME
SA217
WC1 Pressure-containing
parts suitable for high
temperature service.
For service up to 850oF on flanged and weld end valves.
WC6 For service up to 1,050oF flanged end and weld end valves.
WC9 For service up to 1,100oF where good creep strength is required.
C-5 For service up to 1,200oF where good corrosion and oxidation
resistance plus high creep strength are required.
C-12 For service up to 1,200oF. Best corrosion and oxidation
resistance other than stainless grades.
C12A For service up to 1,200oF. Excellent high-temperature properties.
ASTM/
ASME
SA352
LCB
LCC
Ferritic steel castings
for pressure-containing
parts suitable for low
temperature service.
For service down to minus 50oF. This material must be
quenched and tempered to obtain tensile and impact
properties needed at sub-zero temperatures.
LC1 For service down to minus 75oF. A subsequent heat treat is
given to obtain tensile and impact properties at sub-zero
temperatures.
LC2 For service down to minus 100oF. A subsequent heat treat is
given to obtain tensile and impact properties at sub-zero
temperatures.
LC3 For service down to minus 150oF. A subsequent heat treat is
given to obtain tensile and impact properties at sub-zero
temperatures.

CF3 (304-L)
CF8 (304)
Austenitic steel castings
for high temperature
service.
Good creep strength, corrosion and oxidation resistance when
exposed to temperatures above 800oF.
CF3M (316-L)
CF8M (316)
CK20
Same as above except it is resistant to formulation of sigma
phase.
CN7M (A20) Good resistance to hot sulfuric acid. Used extensively in
manufacturing synthetic rubber, high octane gasoline,
solvents, explosives, plastics, heavy and organic chemicals,
and food processing.
CF8C (347) Resistant to intergranular corrosion above 800oF. Excellent for
weld end valves.
ASTM/
ASME
A487
CA6NM (12Cr) Martensitic stainless
steel suitable for high
pressure service.
For service requiring good corrosion resistance and high
tensile and impact properties as well as good pitting
resistance. Excellent weldability and castability. Good for sour
gas service.
ASTM
A747
17-4 PH Precipitation
hardening stainless
steel.
Very high tensile material. Very good when differential
hardness is required due to its resistance to galling. Higher
corrosion resistance than high straight chrome alloy steels.

M35-1 (Monel) For corrosion resistant
service.
Weldable grade. Good resistance to corrosion by all common
organic acids and salt water. Also highly resistant to most
alkaline solutions.
N-12M (Hast-B) Is well suited for handling hydrochloric acid at all concentrations
and temperatures. Good resistance to sulfuric and phosphoric acids.
CW-12M (Hast-C) Good resistance to strong oxidation conditions. Good properties
at high temperatures, high resistance to formic, phosphoric,
sulfurous and sulfuric acids.
CY-40 (Inconel) Very good for high temperature service. Good resistance to
strongly corrosive media and atmosphere.
CZ-100 (Nickel) Same as Inconel except even higher corrosion resistance.
