| Copper | Cu | 28.0 - 34.0 |
| Iron | Fe | 2.5 max |
| Manganese | Mn | 2.0 max |
| Carbon | C | 0.30 max |
| Silicon | Si | 0.50 max |
| Sulphur | S | 0.024 max |

Application Snapshot
Four service blocks dominate: hydrofluoric acid and HF alkylation piping, valve and bolting (chromium-free composition is immune to HF stress corrosion); seawater and marine structures including offshore platform fastening; sour service oil and gas under NACE MR0175 Table A.7; and naval, hydrographic and minesweeping equipment needing relative magnetic permeability below 1.05.
Frequently Asked Questions
Is there a downloadable Monel 400 PDF data sheet? A PDF copy is emailed against project enquiries. Send application, size and quantity to info@torqbolt.com or WhatsApp +91-22-66157017; the PDF returns inside one working day.
Where can I get a certified Monel 400 mill test certificate (MTC)? Every TorqBolt batch ships with an EN 10204 type 3.1 MTC reporting actual cast chemistry against ASTM B127, B164, B564 or F468, plus mechanical results, heat number and PMI. Type 3.2 MTC with independent witness verification is available for sour service and pressure equipment.
