Product Description

Alloy steel 4130 scrap (UNS G41300 / AISI 4130) consists of chromium-molybdenum alloy steel material generated from aerospace components, oil and gas drilling equipment, automotive chassis tubing, pressure vessels, and forged structural parts. Highly prized in metal recycling for its precise chemistry and high strength-to-weight performance, this grade provides a reliable source of chromium and molybdenum.

Chemical Composition Range

  • Chromium: 0.80 to 1.10 percent

  • Molybdenum: 0.15 to 0.25 percent

  • Manganese: 0.40 to 0.60 percent

  • Carbon: 0.28 to 0.33 percent

  • Silicon: 0.15 to 0.35 percent

  • Phosphorus: 0.035 percent maximum

  • Sulfur: 0.040 percent maximum

  • Iron: Balance

Physical Properties and Condition

  • Physical Form: Heavy solids including tube off-cuts, bar ends, plate trimmings, forged rings, structural sections, or clean dense turnings.

  • Cleanliness Standard: Clean, dry material free from heavy rust, oil sludge, grinding dust, cast iron, non-ferrous contaminants, and non-metallic inclusions.

  • Solid Density: 7.85 grams per cubic centimeter.

  • Bulk Density: 2.0 to 4.0 metric tons per cubic meter for solid forms; 1.0 to 1.8 metric tons per cubic meter for loose turnings.

  • Magnetic Property: Strongly magnetic.

  • Melting Point Range: 1430 to 1510 degrees Celsius.

Industrial Applications

  • Electric Arc Furnace Charging: Serves as a key charge material for producing medium-strength chromium-molybdenum structural alloy steels.

  • Induction Furnace Re-melting: Extensively used in foundries for casting high-strength automotive, oilfield, and machinery parts.

  • Secondary Metallurgy Alloy Control: Used as an economical charge ingredient during ladle furnace operations to adjust target chromium and molybdenum levels without using expensive virgin ferroalloys.



Reliable Source of Alloy Recovery

AISI 4130 alloy steel block scrap provides a dependable source of chromium and molybdenum for secondary metallurgy processes. Its consistent composition supports efficient alloy recovery, making it valuable for steelmakers aiming for targeted chemical specifications during steel reprocessing and remelting operations.

FAQ's of Alloy Steel 4130 Scrap:


Q: How can Alloy Steel 4130 Scrap be used in industrial applications?

A: This scrap is primarily utilized for re-melting, alloy recovery, and steel reprocessing. Its AISI 4130 composition makes it suitable for producing new steel products or recovering valuable alloying elements such as chromium and molybdenum.

Q: What is the process for re-melting 4130 Alloy Steel Scrap?

A: The scrap is sorted, cleaned if necessary, and then charged into a furnace where it is melted down with other materials. The resulting molten steel is further processed to meet the desired chemical and mechanical specifications before casting into new products.

Q: Where does the 4130 Alloy Steel Scrap originate from?

A: This scrap is sourced from India and is supplied through a network of dealers, exporters, fabricators, manufacturers, producers, retailers, suppliers, and traders. It typically comes from mixed (used or unused) industrial sources.

Q: What makes Alloy Steel 4130 Scrap beneficial for steelmakers?

A: Its high alloy content and reliable chemical composition, particularly the presence of chromium and molybdenum, allow steelmakers to efficiently achieve specific alloy recoveries. The scrap's high purity and minimal contamination further enhance smelting efficiency.

Q: When is Alloy Steel 4130 Scrap recommended for steel reprocessing?

A: It is recommended when steel plants require secondary alloying material rich in Cr and Mo to meet stringent metallurgical requirements or when cost-effective alternatives to virgin alloys are needed.

Q: How does the surface finish of this scrap affect its usability?

A: The rusty and sometimes painted surface is characteristic of industrial scrap, but it does not significantly affect its re-melting performance. Any surface oxidation is typically absorbed during smelting, offering no hindrance to alloy recovery.
