304 Stainless Steel Scrap is one of the most common and widely traded austenitic stainless steel grades. Often referred to as 18/8 stainless, Type 304 contains approximately 18% chromium and 8% nickel, giving it a useful combination of corrosion resistance, formability, weldability and durability.
Because 304 is widely used across food processing, manufacturing, construction, transportation and consumer products, it is also one of the stainless grades most frequently encountered by scrap yards and metal processors.
What Is 304 Stainless Steel?
Type 304, also known as UNS S30400, is a chromium-nickel austenitic stainless steel. Standard 304 specifications generally contain 18% to 20% chromium, 8% to 10.5% nickel and no more than 0.08% carbon.
The alloy has excellent forming and welding characteristics and maintains useful corrosion resistance across a broad range of indoor, outdoor and industrial applications.
304 cannot be hardened by conventional heat treatment, although cold working can increase its strength and hardness.
Common Uses of 304 Stainless Steel
- Commercial and residential sinks
- Kitchen equipment and cookware
- Food-processing and beverage equipment
- Storage tanks and vessels
- Architectural panels, railings and trim
- Chemical containers and processing equipment
- Heat exchangers
- Transportation components
- Appliances
- Industrial fabrication scrap
304 Stainless vs. 316 Stainless
304 and 316 Stainless Steel can look almost identical, making visual identification unreliable.
The major alloying difference is that 316 contains molybdenum, while standard 304 does not. Molybdenum improves resistance to localized corrosion, particularly pitting and crevice corrosion in chloride-containing environments.
Because 316 contains additional alloying elements, it may carry a different scrap value from 304. For commercial quantities, processors may use source documentation, handheld XRF analyzers or other positive material-identification methods to distinguish the grades.
Is 304 Stainless Steel Magnetic?
Annealed 304 stainless is generally non-magnetic or only weakly magnetic. However, cold working, forming and fabrication can cause some 304 material to develop a magnetic response.
A magnet can therefore be useful as a preliminary sorting tool, but it should not be used by itself to confirm that a material is 304 stainless.
304 Stainless Solid vs. 304 Turnings
Scrap yards may purchase different forms of 304 stainless under separate grades.
- 304 Stainless Steel Solid: Clean sheet, plate, pipe, tanks, fittings and other solid stainless material.
- 304 Stainless Steel Turnings: Machining chips, shavings and turnings produced during manufacturing.
- Irony or contaminated 304: Stainless carrying significant carbon-steel attachments or other contamination.
Turnings may be priced differently from solids because they can contain cutting oils, moisture, fines or mixed alloys and may require additional processing.
What Affects 304 Stainless Steel Scrap Prices?
304 Stainless Steel Scrap prices depend on nickel and chromium market conditions, material form, cleanliness, alloy certainty, contamination, quantity, location and buyer requirements.
Clean, identified 304 solids may command a different price from mixed stainless, turnings, non-magnetic stainless or material carrying substantial iron attachments.

How to Maximize 304 Stainless Scrap Value
- Keep verified 304 separate from ordinary carbon steel.
- Separate 304 from 201, 301, 316 and higher-alloy stainless where practical.
- Keep clean solids separate from oily turnings and machining chips.
- Remove excessive carbon-steel attachments, rubber, plastic and other contamination when economically practical.
- Preserve mill certificates, fabrication records or other alloy documentation for industrial quantities.
- Use positive material identification when processing mixed or high-value stainless loads.
- Confirm the buyer's preparation and size requirements before processing a large shipment.
Where Can You Sell 304 Stainless Steel Scrap?
304 stainless is purchased by metal recyclers, stainless-steel processors and specialty-alloy buyers. RecyclingMonster's Metal Recycling Center Directory can be used to locate scrap yards and processors by location.
You can also use RecyclingMonster's Recycle an Item tool, which includes searchable categories for Stainless (304), 304 non-magnetic stainless and related stainless grades.
Have Large Quantities of 304 Stainless?
Manufacturers, food processors, fabricators, demolition contractors and industrial facilities generating larger quantities should segregate 304 at the point of generation whenever possible.
For commercial loads, ask buyers whether they price clean 304 solids, turnings and contaminated stainless separately. Container service, pickup arrangements, alloy verification and delivered-versus-pickup pricing can also affect the net value of a large shipment.
