Iron vs Steel Scrap — What's the Difference?

How to Identify Iron vs Steel

Iron and steel are both ferrous metals, but they have key differences that affect their scrap value:

• Cast Iron — heavy, brittle, has a rough/granular texture when broken. Common in old machinery, pipes, engine blocks, and cookware.
• Wrought Iron — tough, malleable, often found in gates, railings, and decorative items. Has a fibrous grain visible when broken.
• Steel — an alloy of iron and carbon. Lighter than cast iron, stronger, and more versatile. Used in construction rebar, structural beams, automotive parts, and appliances.
• Stainless Steel — steel with chromium added. Non-magnetic (mostly), rust-resistant, higher value. Common in kitchen equipment, medical instruments, and food processing.

The quickest test: use a magnet. Both iron and mild steel are strongly magnetic. Stainless steel is usually non-magnetic or weakly magnetic.

Common Sources of Each

In Pakistan's industrial landscape:

• Iron — old machinery, engine blocks, manhole covers, water pipes, industrial castings
• Mild Steel — construction rebar, structural beams, car bodies, sheet metal, roofing
• Stainless Steel — hotel kitchen equipment, medical equipment, food processing machinery

How Grading Works for Each

Scrap iron and steel are graded based on:

• Density — heavy melting steel (HMS) vs light iron (tin cans, thin sheet)
• Cleanliness — free from concrete, wood, plastic, or other attachments
• Size — pre-cut pieces vs. large structures requiring dismantling
• Alloy content — plain carbon steel vs. alloy steel vs. stainless steel

Industries That Produce Each Type

Different industries generate different iron and steel scrap:

• Manufacturing — steel offcuts, defective parts, old tooling
• Construction — rebar, structural steel, corrugated sheets
• Automotive — car bodies, engine blocks, suspension parts
• Shipping — ship-breaking steel, marine hardware, containers

Krusco's Buying Process for Both

At Krusco's metal recycling division, we buy all grades of iron and steel scrap:

• On-site sorting — we separate ferrous grades at your location
• Digital weighing — each grade weighed separately on certified scales
• Fair market rates — regularly updated to reflect current demand
• Complete documentation — weighment slips and GST invoices provided
• Own shearing and baling equipment — we can process large pieces on-site

From a single truckload of mixed iron to monthly factory contracts, we handle it all. Book a pickup today.
