A351 CF8M Cast NPT Elbow Class 150 LB MSS-SP-114 Casting Fitting
We are a manufacturer of A351 CF8M Cast NPT Elbow Class 150 LB MSS-SP-114 Casting Fitting in China.
A cast elbow is a pipe fitting used to change the direction of flow in a piping system. It is manufactured by casting process.
Normally Casting elbow are used for low pressure,say 150lbs. and with threaded end.
A351 CF8M Cast Elbow Thread type:NPT, PT, BSPP, BSPT
- 90° Elbow: Changes the flow direction by 90 degrees.
- 45° Elbow: Changes the flow direction by 45 degrees.
CF8M is a cast austenitic material for pressure containing parts, which covered by ASTM A351 and ASTM A743 and ASTM A744 standard.
Chemical Composition of CF8M ASTM A351
The typical chemical composition of CF8M is as follows (weight percentage):
| Element | Content (%) | Function |
|---|---|---|
| Carbon (C) | ≤ 0.08 | Improves strength; low carbon ensures corrosion resistance. |
| Manganese (Mn) | ≤ 1.50 | Enhances toughness and wear resistance. |
| Silicon (Si) | ≤ 2.00 | Improves strength and oxidation resistance. |
| Phosphorus (P) | ≤ 0.04 | Kept low to prevent brittleness and enhance durability. |
| Sulfur (S) | ≤ 0.04 | Kept minimal to maintain toughness and machinability. |
| Chromium (Cr) | 18.00 – 21.00 | Provides corrosion resistance by forming a passive oxide layer. |
| Nickel (Ni) | 9.00 – 12.00 | Adds toughness and improves resistance to corrosion. |
| Molybdenum (Mo) | 2.00 – 3.00 | Enhances pitting and crevice corrosion resistance, especially in chloride environments. |
| Iron (Fe) | Balance | Forms the base of the alloy. |
