Review Hot-rolled steel billet for the 150 × 150 mm specification. Check material grade, dimensions, inspection documents and delivery requirements before requesting a quotation.
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.
For 150 × 150 mm billets, define length, tolerances, grade and the intended rolling process. Include required heat identification and analysis documents. Availability, lead time and pricing are confirmed against the complete enquiry, not the section size alone.

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.

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.
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.

Size specifications: Hot-rolled steel billet 150 × 150 mm
For 150 × 150 mm billets, define length, tolerances, grade and the intended rolling process. Include required heat identification and analysis documents. Availability, lead time and pricing are confirmed against the complete enquiry, not the section size alone.
Choosing this specification
For 150 × 150 mm, check the receiving mill’s entry dimensions, reheating route and required finished product. The cross-section alone does not establish rolling yield or grade suitability; confirm length, chemistry and surface acceptance. At nominal geometry and 7850 kg/m³ steel density, the reference is 176.625 kg per metre. This calculation excludes tolerances, coatings, corner radii and process losses; it is not certified shipping weight or a load rating. Compared with 130 × 130 mm, the nominal geometric reference is 33.1% higher on the same basis. This comparison supports quantity planning; it does not establish interchangeability.
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.
Buying Hot-rolled steel billet 150 × 150 mm and requesting a price
The price for Hot-rolled steel billet 150 × 150 mm depends on the material specification, quantity, production or processing requirements, inspection, packing, freight and delivery schedule.
