HT200 gray-iron sand-cast parts are available with separately specified QT400 ductile-iron component enquiries. Choose the complete governing designation and material condition for the actual item. A one-piece minimum is stated for the selected casting request.
Define the component and selected iron
Provide the actual drawing and describe the part’s working role within its assembly. Identify the mounting, locating and mating relationships relevant to material selection. Keep the two iron families separate and establish the full ductile designation without assuming an unspecified suffix.
Set precision at the required interface
For an unsigned 0.02 mm tolerance requirement, specify the controlled feature, permitted deviations and processing stage. Mark the drawing references and measurement conditions used for acceptance. Distinguish cast-state regions from interfaces needing a particular final result for their installed fit.
Agree inspection and supplied surfaces
The stated 100% inspection needs actual material, dimensional and surface checks for the chosen component. Identify the acceptance records required and explain any initial-item assessment against its mating parts. Define appearance and contact conditions where the supplied surface affects use.
- State the HT200 or separate QT400 item’s quantity and controlling revision.
- Describe the operating duty and required material condition.
- Request applicable ISO9001:2015 documents and activity scope.
- Retain accepted grade and interface changes within the component record.
Use that approved casting definition when confirming subsequent parts for the same working arrangement.
