What is ISRI 211 Shredded Scrap?
ISRI 211 shredded scrap is a type of shredded steel scrap that meets the specifications set by the Institute of Scrap Recycling Industries (ISRI). It consists of homogeneous, magnetically separated iron and steel scrap that has been processed through a shredding system. This scrap is free from non-metallics and contaminants, making it highly valuable in the steel recycling industry.
ISRI 211 Specification
The ISRI 211 specification defines the composition and quality requirements of shredded steel scrap:
- Material Composition: Iron and steel scrap that has been shredded into uniform pieces.
- Size: The shredded pieces should typically pass through a 5-inch (127 mm) sieve but not exceed 2% of material above 9 inches (228 mm).
- Density: A minimum density of 50 pounds per cubic foot (800 kg/m³).
- Contaminants: Free from dirt, non-ferrous metals, excessive rust, and any other non-metallic materials.
- Radioactive and Hazardous Material: Must be free from radioactive or hazardous waste.
What is the ISRI Scrap Specification?
The ISRI scrap specification is a standardized guideline developed by the Institute of Scrap Recycling Industries to ensure consistency and quality in the trade of recycled metals. ISRI 211 is one of the classifications within the ISRI code system, specifically defining shredded steel scrap with uniform density and size for use in steel mills and foundries.
What is the HS Code for Shredded Scrap?
The Harmonized System (HS) code for shredded steel scrap, including ISRI 211, is 7204.49.00. This code is used globally for the classification of ferrous waste and scrap, ensuring uniformity in international trade regulations.
What is the Density of Shredded 211 Scrap?
The average density of ISRI 211 shredded scrap is 50 pounds per cubic foot (800 kg/m³) or higher. Density testing ensures that the scrap meets the required standards for efficient melting and processing in steel production.
Methods to Test the Average Density of ISRI 211 Scrap
To ensure compliance with ISRI standards, various methods are used to test the density of shredded steel scrap:
- Weighing and Volume Measurement: The scrap is placed in a container of known volume and weighed to determine density.
- Bulk Density Testing: Using industrial-grade densimeters, the weight per cubic meter of scrap is calculated.
- Magnetic Separation Testing: Ensuring the material is free from excessive non-ferrous metals and non-metallic contaminants.
- Moisture Content Testing: Ensuring moisture levels do not exceed allowable limits to prevent weight misrepresentation.
ISRI Code List: understanding the 210-211 Grades
The ISRI Code 210-211 classification includes different grades of shredded steel scrap:
- ISRI 210: Similar to ISRI 211 but with different size or density requirements.
- ISRI 211: Homogeneous shredded steel scrap with a defined size and density.
Shredded Steel Scrap ISRI 211 Price
The price of ISRI 211 shredded scrap fluctuates based on several factors, including:
- Global steel demand and market conditions
- Quality and density of the scrap
- Regional supply and logistics costs
- Current ferrous metal trading prices on the LME (London Metal Exchange)
Uses of ISRI 211 Shredded Scrap
Shredded steel scrap ISRI 211 is widely used in:
- Steel mills for producing new steel products.
- Foundries for melting into cast iron and steel components.
- Construction and infrastructure projects for reinforcement materials.
- Automotive manufacturing for body panels and structural parts.
ISRI 211 shredded scrap is a valuable and standardized form of ferrous scrap metal used extensively in the steel recycling industry. Understanding ISRI 211 specifications, density, HS codes, and pricing is crucial for scrap metal traders and steel manufacturers. The growing demand for recycled steel makes shredded steel scrap ISRI 211 an essential component in sustainable metal production and global trade.
