Parameter	Value
Dimensional / material references	ISO 10835 sampling; product form and cargo requirements by agreement
Grade / material	DRI / HBI

Geometric estimates exclude rolling tolerances, coatings and process losses; hollow and rolled-section references include their own section-table basis. Calculated bar weights use unrounded mass. Values are not measured shipment weights. Confirm length, grade, manufacturing route, packing and supply in the offer; the existing image illustrates the product family.

Direct reduced iron (DRI) Technical and buying guide

EMRA Steel

DRI, also called sponge iron, is produced by reducing iron oxides and is used as steelmaking feedstock.

Standards and applicability

Set numeric acceptance limits and sampling for the actual product and lot; these analysis tables identify required enquiry fields, not a universal grade or a declared shipment analysis. State dry/as-received basis, moisture, particle distribution and settlement weighing where applicable. Use the applicable analytical methods agreed in the contract; structural tensile/yield tables do not apply to these feedstocks. M = Fe_metal / Fe_total × 100 (%).

Selected percentages by mass and test values are reference requirements within the stated scope, not the actual heat analysis or a complete specification. A dash means no value is declared here, not zero. Compare the offered heat and test results with the applicable specification and inspection document. If EN 10204 type 3.1 is required, agree document availability, heat traceability and test scope before ordering.

Inspection and export enquiry

Send the exact product, size, full grade and standard edition, delivery condition, quantity, test requirements and named destination. Confirm cutting, coating, bundle or coil mass, protection, unloading and the Incoterms delivery point in the quotation. The destination guidance below supports port and inland comparisons; it does not confirm local stock or a fixed price.

Chemistry references and commercial grades

DRI and HBI · published producer specification examples

These are example limits from one published producer specification, not common limits for every DRI/HBI grade. Metallization = metallic Fe / total Fe ×100, using the same sample and basis. Gangue here is CaO + Al₂O₃ + MgO + SiO₂. Also agree moisture, fines, bulk density and sampling; DRI and HBI remain distinct delivery forms.

DRI and HBI · published producer specification examples
Form / diameter	Total Fe (%)	Metallic Fe (%)	Metallization (%)	C (%)	Total gangue (%)	P (%)	S (%)
DRI	≥90.5	≥84.0	≥92.5	≥2.20	≤4.8	≤0.06	≤0.01
HBI	≥90.5	≥84.0	≥92.5	≥0.90	≤4.8	≤0.06	≤0.01

Reference values are not shipment analysis or an inventory promise. Agree the complete specification, sampling basis, test methods and acceptance limits before ordering; confirm actual results on the heat/lot certificate. A dash means no numeric limit is stated in this selected reference, not zero.

Specification and dimensions

Specify the following dimensions or analysis details for Direct reduced iron (DRI): Iron content, metallization, carbon, impurities and product form. The examples below are enquiry references, not a confirmed stock range.

Grades and applicable standards

For Direct reduced iron (DRI), agree the required chemical composition, quality limits, sampling and acceptance criteria with the supplier. Specify any governing material specification; finished structural-steel standards should not be assumed to cover raw materials.

Applications and project requirements

For Direct reduced iron (DRI), share the intended production process or project specification. Required properties, processing condition, surface acceptance and dimensional tolerances should reflect the actual application. Supply selection should be reviewed against the technical requirements rather than based on dimensions alone.

Inspection and traceability

Agree heat or batch identification, chemical analysis, applicable tests and dimensional checks before ordering. Specify inspection documents, acceptance criteria and any independent inspection requirements.
