A gear material decision must fit the tooth geometry, duty and manufacturing route. Familiarity with a grade name is not enough. Define whether you are buying stock, a forged blank or a finished gear.
Specify what must be delivered
Ovako notes that tooth flanks experience contact pressure while tooth roots experience bending stress. Surface hardness alone therefore cannot describe the whole requirement. Follow the approved drawing for material condition, surface treatment where specified, core requirements and acceptance tests. Do not assume one treatment route fits every gear.

Provide the drawing revision, approved grade and standard, blank form, dimensions, quantity and delivery schedule. For finished gears, include tooth geometry, accuracy requirements, heat treatment, finishing and inspection scope. Keep stock certificates linked to machining lots and final inspection records. Any material substitution needs technical review before purchase.
