|||
| 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. |
|||
| Stainless Steel |
ASTM/ ASME SA351 |
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. |
|||

|||
| 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. |
