Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits

Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

New manufacturing waste from precision machining; fine fragmented material with oil/coolant residue; requires processing (drying/compression) before furnace use

Acceptable Inclusions

Machining oil <2% total (inherent to turnings source)
Coolant residue <1% (water-based or synthetic)
Fine iron oxide (oxidation from machining)
Light rust from processing/storage

Prohibited Materials

Copper contamination >0.15% (above spec limit)
Stainless steel chips (segregation requirement)
Non-ferrous metals >0.5% each (aluminum, brass, zinc)
Synthetic polymer contamination (plastics from coolant)
Radioactive materials
PCB or hazardous electronics
Asbestos materials
Mercury components
Excessive oil >2% (furnace damage risk)

Quality Assurance

Testing protocols, sampling methods, and acceptance criteria.

Sampling Protocol

frequencyRandom sampling from different depths of load

maximumQuantity30 samples per truck

minimumQuantity500kg or 15 samples

notesTurnings highly variable; oil content stratifies during storage

percentage5–10% of lot

Acceptance Limits

all Criteria Must Passcriteria must be met; oil content especially critical

carbon ContentC <0.35%

copper LimitCu <0.15%

iron ContentFe ≥95.0%

non Ferrous Total<2.0% combined

oil ContentOil <2.0%

phosphorusP <0.08%

sulfurS <0.08%

visual Contaminants<1% non-ferrous visible; no stainless; no hazmat

Weight Tolerance

notesTurnings variable density; wider tolerance than solid scrap

variance±5% acceptable from purchase order weight

Required Test Methods

Visual Inspection

Method 1

Purpose

Detect oil saturation level, coolant appearance, stainless/non-ferrous contamination

Acceptance Criteria

Pass: Oil color normal (not excessively dark/saturated)
<2% oil apparent
no stainless/non-ferrous visible

Procedure

100% visual scan
assess oil saturation by color/appearance

Oil Content Testing

MANDATORY

Method 2

Purpose

Verify oil content <2% (defines grade acceptance)

Acceptance Criteria

Pass: Oil <2% by weight after drying

Procedure

test
critical for furnace compatibility

XRF Spectrometry

Method 3

Purpose

Verify Fe ≥95%, C <0.35%, Cu <0.15%, non-ferrous <2%

Acceptance Criteria

Pass: Fe ≥95%, C acceptable, Cu <0.15%, non-ferrous <2%

Combustion Analysis

Method 4

Purpose

Verify carbon <0.35%, sulfur <0.08%

Acceptance Criteria

Pass: C <0.35%, S <0.08%

Procedure

Test on dried samples
burning off oil first

Magnetic Test

Method 5

Purpose

Confirm ferrous material
detect stainless contamination

Acceptance Criteria

Pass: Strong ferrous response
no stainless detected

Procedure

Hand magnet test on dried samples
