EMRA Steel supports sourcing enquiries for Steel billet. Review product dimensions, grades, standards and inspection requirements before requesting a quotation. Confirm quantity, delivery destination and the required schedule with our sales team.
Hot-rolled steel billet: Size and weight portfolio
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.

Standards and applicability
Specify the cast cross-section and cut length, full heat chemistry, deoxidation, surface acceptance, internal soundness and downstream rolling route. Finished EN 10025 mechanical values cannot certify an unrolled billet or slab. For 3SP/5SP requests, provide the complete GOST or other agreed specification and edition; no universal numerical chemistry is assigned from a short commercial name.

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
3SP and 5SP · GOST 380-2005 ladle analysis
3SP and 5SP refer here to fully killed Ст3сп and Ст5сп. These chemistry references support billet/slab enquiries; casting quality, residual elements, steelmaking-route exceptions and the downstream product standard remain separate order requirements. Finished rolled-steel mechanical properties do not certify an as-cast billet or slab.

Requested minimum manganese: 0.50% and 0.60%
Mn +0.50 and Mn +0.60 mean Mn ≥0.50% and Mn ≥0.60%. The table intersects each buyer minimum with the grade range. They are optional purchase limits, not new standard grade names. St52-3 has a maximum Mn limit in the reference below; a minimum of 0.50% or 0.60% requires separate mill agreement.

St37, St44 and St52 · historical DIN 17100 reference
Ladle-analysis reference for St37-2, St44-2 and St52-3 at t ≤16 mm only. Bare St37/St44/St52 names need a suffix, edition and delivery condition. Other thicknesses and product analysis have different rules. These legacy grades are not automatically equivalent to EN grades or interchangeable with CK45/CK60. For semi-finished feedstock, agree chemistry and downstream qualification separately.

Steel billet Technical and buying guide
EMRA Steel supports sourcing enquiries for Steel billet. Review product dimensions, grades, standards and inspection requirements before requesting a quotation. Confirm quantity, delivery destination and the required schedule with our sales team. 250 × 250 mm
Billets are semi-finished steel stock for further rolling. Cross-section and chemistry should suit the downstream process.
Specification and dimensions
Specify the following dimensions or analysis details for Steel billet: Diameter and length for bars and rebar; diameter and coil weight for wire rod; billet cross-section and length.. The examples below are enquiry references, not a confirmed stock range.
Grades and applicable standards
For Steel billet, 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 Steel billet, 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.

Billet Sizes and Lengths
The reference catalogue describes square sections from 100 to 250 mm and length options of 6 and 12 m. Examples listed include 125 × 125 mm and 150 × 150 mm. These are enquiry references, not a confirmed EMRA Steel stock range. State both section dimensions, exact length, tolerances and total tonnage.
Standards and Technical Acceptance
Where a GOST 380 grade is requested, confirm its full designation and the agreed chemical requirements. Do not assume equivalence to an EN structural steel grade. EN 10025-2 concerns finished structural steel delivery requirements and should not be used alone as a complete billet casting and acceptance specification. Agree surface acceptance, dimensions, traceability and inspection documents for the billet order.
