Review Forged grinding steel balls for the 40 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.
Requested specification: 40 mm. Confirm dimensional tolerances, material analysis, processing condition and packing for the intended application. Listed examples are enquiry references and require supply confirmation.

Standards and applicability
A grinding-ball diameter does not establish composition, hardness or wear life. Agree forged versus cast/rolled route, heat treatment, surface/core hardness method and profile, impact/breakage test, wear test conditions and sampling. The chemistry/acceptance matrix below requires actual batch limits; it is not a universal grinding-ball standard or a promise that a bar grade achieves a particular HRC.

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.
Published ball-producer examples for 40 and 80 mm only; do not interpolate them to 60 mm or treat them as a universal ball grade. Confirm chemistry and heat treatment for each diameter. Surface/core hardness, impact resistance, breakage and wear require agreed test methods and lot acceptance; rod chemistry alone does not establish finished-ball performance.
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.
Size specifications: Forged grinding steel balls 40 mm
Requested specification: 40 mm. Confirm dimensional tolerances, material analysis, processing condition and packing for the intended application. Listed examples are enquiry references and require supply confirmation.
Choosing this specification
For 40 mm, match ball diameter to the mill’s approved charge specification and feed conditions. Confirm hardness, material, manufacturing route and wear acceptance separately; diameter alone does not determine grinding performance. At nominal geometry and 7850 kg/m³ steel density, the reference is 0.263 kg per piece. This calculation excludes tolerances, coatings, corner radii and process losses; it is not certified shipping weight or a load rating. Compared with 60 mm, the nominal geometric reference is 70.4% lower on the same basis. This comparison supports quantity planning; it does not establish interchangeability.
Buying Forged grinding steel balls 40 mm and requesting a price
The price for Forged grinding steel balls 40 mm depends on the material specification, quantity, production or processing requirements, inspection, packing, freight and delivery schedule.
