Steel processing enquiries
Processing scope depends on the material, dimensions, required finish and application.
Specify spheroidizing, softening or stress-relief requirements, the material grade and the condition required for subsequent processing.
Provide incoming and finished dimensions, dimensional tolerance and straightness requirements. Include the intended downstream operation.
Define the required surface condition, machining allowance and inspection method. Discuss peeling, grinding or finishing requirements with the enquiry.
Processing quotation
Prices depend on the agreed specification. There are no fixed processing packages.
Include the material grade, section size, current condition, required final condition, batch quantity and any specified hardness or microstructure requirements.
Send nominal diameter, permitted deviation, straightness, length, surface requirements, machining allowance and inspection criteria.
The material, required operations, acceptance criteria, documentation and delivery terms should be reviewed together before an order is placed.
