maximumQuantity50 samples per load
minimumQuantity2–3 tonnes or 30–40 samples
notes316 grade verification critical; molybdenum must be confirmed; higher sampling intensity
percentage10–15% of lot
Acceptance Limits
all Criteria Must Passcriteria including molybdenum confirmation pass
carbon LimitC <0.08%
chromium RangeCr 16.0–18.0%
iron RangeFe 62–68%
magnetic Testmagnetic response
molybdenum RangeMo 2.0–3.0%
nickel RangeNi 10.0–14.0%

Required Test Methods
Magnetic Test
Purpose
- Confirm non-magnetic austenitic
- exclude ferromagnetic materials
Acceptance Criteria
- Pass: NO magnetic response (austenitic 316)
Procedure
- Handheld magnet on every piece
- zero magnetic response
XRF Spectrometry
CRITICALMANDATORY
Purpose
- Verify Mo 2–3% (316 grade defining element)
- Cr 16–18%, Ni 10–14%, Fe 62–68%
Acceptance Criteria
- Pass: Mo 2.0–3.0% CONFIRMED (critical 316 vs. 304)
- Cr/Ni/Fe in range
Procedure
- XRF on every sample
- no estimation acceptable
Combustion Analysis
Purpose
- Verify carbon <0.08%, sulfur <0.03%
Acceptance Criteria
- Pass: C <0.08%, S <0.03%
Grade Confirmation Test
CRITICAL
Purpose
- Distinguish 316 (Mo 2–3%) from 304 (Mo absent)
Procedure
- XRF molybdenum range verification
- if Mo <2% OR >3% =
