- Up to 3x yield & 2x tensile strength of 400
- Higher cost, longer lead time on age-harden lots
- Best for shafts, fasteners & high-load components
Need An Exact Pressure Rating Certificate?Send OD, wall thickness & design temperature – we calculate and confirm.
NACE MR0175 Sour-Service Compliance For Monel Pipe
Offshore and gas-field buyers ask for this compliance sheet before any Monel K-500 order is confirmed.
Controlled Age-Hardening Cycle
Heat treatment window is tightly controlled to limit hardness for sour duty
≤ 35 HRC Hardness
Every K-500 lot is hardness-checked so no pipe crosses the sour-service limit
ISO 15156-3 Recognised
Chemistry & hardness combination accepted for global offshore contracts
Need A Signed NACE Compliance Statement?Send project name & PO reference – we prepare it against your order.
How To Choose A Genuine ASTM B165 Monel Pipe?
Ask For Heat-Wise MTC 3.1
Certificate must show chemistry, tensile & heat number matching the pipe marking
Step 1
Request PMI Spot Verification
Ni & Cu reading on the pipe body must match the MTC values
Step 2
Check End-Stamp Markings
Grade, standard, heat number & manufacturer logo should be die-stamped
Step 3
Verify Third-Party Inspection
SGS, BV or TUV report confirms independent test results
Step 4
