Scrap stainless steel Brisbane
Scrap stainless steel Brisbane: identify 304, 316 and mixed items
Send grade markings, the original application and clear photos; appearance or a magnet test alone may not identify the alloy reliably.
Illustrative industry image
Material overview01
Start with the stainless steel form
Stainless steel covers multiple alloys with different nickel, chromium and molybdenum content. 304 and 316 can look alike, while fabrication, corrosion, coatings, iron attachments and mixed assemblies can complicate identification.
Common enquiry examples
- 304 sheet, tube and fittings
- 316 marine and process items
- Fabrication offcuts
- Commercial kitchen equipment
- Tanks and process equipment
- Mixed stainless assemblies
Acceptance is load-specific
Grade guide02
How stainless steel is described
Use the closest description you can support, then show the material clearly. Final identification is based on the actual parcel.
- 304 stainless steel
- Common sheet, tube, fittings and fabricated items. Markings, certificates or analyser verification may be needed when the grade affects the quote.
- 316 stainless steel
- Often used in marine, chemical and process environments. Do not rely on appearance alone; send markings, application details or test evidence where available.
- Stainless turnings and offcuts
- Keep known alloy groups separate and identify cutting fluids, moisture, scale and other contamination. Mixed swarf may need load-specific assessment.
- Mixed stainless assemblies
- Equipment with carbon-steel frames, motors, insulation, rubber, glass or other components is assessed from the complete construction and preparation required.
Quote basis03
What can change the assessment
A material name is only the start. Composition, preparation, quantity and handling details make the quote useful.
- Verified alloy
- 304, 316 and other stainless grades have different composition. Markings or analyser verification can matter to the commercial basis.
- Iron and mixed attachments
- Carbon-steel frames, fasteners, motors, insulation and non-metal components reduce the recoverable stainless proportion.
- Condition and contamination
- Oil, cutting fluid, moisture, coatings, heavy scale and process residue need to be identified before movement.
- Separation and measured weight
- Keep known alloys apart and confirm any weight-based terms from the measured net material weight.
MetalBase does not publish a generic rate on this guide. Request a current assessment for the actual material and confirm the terms before handover.

Prepare four useful details
Clear photos and realistic measurements reduce avoidable back-and-forth.
- 01
Record markings
Photograph grade stamps, certificates, nameplates and the original application where known. - 02
Keep alloys separate
Do not combine known 304, 316 and unidentified stainless when they can be kept apart. - 03
Show mixed construction
Include frames, fasteners, motors, insulation, rubber and other attachments in the photos. - 04
Identify residue
Describe oil, cutting fluid, moisture or process residue and provide any relevant cleaning records.

Can a magnet distinguish 304 from 316 stainless steel?
Not reliably. Cold working and fabrication can affect magnetic response, and both grades may require markings, documentation or analyser verification when identification matters.
Why should 304 and 316 stainless be separated?
Their alloy composition differs. Keeping verified grades separate avoids turning identifiable material into an uncertain mixed parcel.
Can stainless equipment with a steel frame be included?
Include it in the enquiry and show the complete construction. Attached carbon steel, motors, insulation and other material can affect preparation, handling and assessment.
Are stainless steel scrap prices listed here?
No. Verified alloy, cleanliness, attachments, quantity, measured weight and market movement can affect the commercial basis. Request a current assessment.
