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.

Ferritic stainless steel scrap; MAGNETIC (differs from austenitic 304/316); cost-effective stainless alternative

Acceptable Inclusions

Surface oxidation and discoloration (ferritic typical)
Light grease/oil <1%
Paint coating (burns off)
Mill scale

Prohibited Materials

Austenitic stainless (304, 316 mixing with 430)
Carbon steel mixing (CRITICAL; 100% segregation)
Copper or brass components (non-ferrous)
Non-ferrous metals >0.5% each
Radioactive materials
PCB or hazardous electronics
Asbestos materials
Mercury components
Excessive nickel (>0.75% indicates grade mixing)

Quality Assurance

Testing protocols, sampling methods, and acceptance criteria.

Sampling Protocol

frequencyRandom selection from different material pieces

maximumQuantity40 samples per load

minimumQuantity1–2 tonnes or 20–30 samples

notesMagnetic test helps identify 430 vs. austenitic; ferritic more consistent than austenitic

percentage5–10% of lot

Acceptance Limits

all Criteria Must Passcriteria must be met; magnetic + Ni <0.75% especially critical

carbon LimitC <0.12%

chromium RangeCr 16.0–18.0%

iron RangeFe 80–88%

magnetic Responsemagnetic pull

molybdenumMo <0.1%

nickel LimitNi <0.75%

silicon RangeSi 1.0–2.0%

sulfur LimitS <0.03%

Weight Tolerance

variance±3% acceptable from purchase order weight

Required Test Methods

Magnetic Test

CRITICAL

Method 1

Purpose

Identify ferritic 430 (magnetic) vs. austenitic 304/316 (non-magnetic)

Acceptance Criteria

Pass: STRONG magnetic response (ferritic 430 confirmed)

Procedure

Handheld magnet on every piece
strong pull = 430
no pull = austenitic (contamination)

XRF Spectrometry

CRITICAL

Method 2

Purpose

Verify Cr 16–18%, Ni <0.75% ( nickel limit), Fe 80–88%

Acceptance Criteria

Pass: Cr 16–18%, Ni <0.75% (MUST verify <0.75%), Fe within range

Combustion Analysis

Method 3

Purpose

Verify carbon <0.12%, sulfur <0.03%

Acceptance Criteria

Pass: C <0.12%, S <0.03%

Nickel Verification

Method 4

Purpose

Confirm nickel <0.75% (defines ferritic 430)

Procedure

XRF or ICP-AES must explicitly confirm Ni <0.75%
if >1.5% = austenitic contamination
