Specify the delivered rod
JOTAIN supplies finished, heat-treated 65Mn grinding rods. Send the rod diameter, ordered length and mill duty; alternative materials need a separate technical review.

Grade route 06
66Mn4 / 65Mngrinding rod steel
66Mn4, 65Mn, and SUP6 should be reviewed as separate standard routes for grinding rods and wear-related rod products; the controlling standard, condition, and purchaser approval govern the order.
Product supply
65Mn grinding rods
JOTAIN supplies grinding rods in a regular diameter range of 60–160 mm, with heat treatment, straightening, fixed-length cutting, inspection, marking and export packing.
Agree the heat-treatment result
Agree dimensional tolerances, straightness and hardness requirements, including test method and locations. Record the accepted specification and lot identification in the order.
Review rod inspection and traceability →Compare performance in your mill
Use matched operating periods to compare consumption in kg/t, breakage and bending. The trial ledger records your measurements; it does not represent a published JOTAIN performance result.

RFQ checks
Questions buyers ask first.
Is 65Mn only selected by chemical grade name?
No. 65Mn grinding rod review should connect grade, diameter, heat treatment, hardness, toughness, operating condition, inspection, packing, marking, and destination. The complete route matters for wear-related service.
What operating data helps a 65Mn grinding rod RFQ?
Useful RFQ data includes mill type, current rod grade, rod diameter, length, wear profile, breakage or bending issues, hardness target, replacement pattern, rod life, downtime, quantity, packing requirement, marking, destination, and trial-batch preference.
What inspection details matter for grinding rods?
Common inspection details include chemical composition, hardness or mechanical verification if specified, dimensional inspection, surface condition check, certificate / MTC, heat number traceability, third-party inspection records, packing list, marking, and shipment document needs.
