Heavy Steel Casting RFQ Checklist: What to Prepare Before Requesting a Quote

A heavy steel casting RFQ should help a supplier understand the component you need, the condition in which it must arrive and the requirements it must satisfy. That applies whether you are buying a new mill component, replacing a slag pot or sourcing a casting for a machinery project.

If each supplier receives a different version of the requirement, the resulting prices may cover different scopes. A useful enquiry gives everyone the same starting information and asks them to identify assumptions, exclusions and questions.

Start with the information available. Separate confirmed requirements from items still awaiting an engineering decision, then resolve those items before accepting a production quotation.

Five things to send with your first enquiry

For an initial discussion, prepare:

1. Component and application. Name the part and explain which equipment or project it belongs to.
2. Available technical files. Attach the current drawing, model or specification, with its revision and units.
3. Quantity. State the immediate order quantity and identify any possible repeat requirement separately.
4. Required delivery condition. Explain whether you need a casting blank, selected machining operations or a finished component.
5. Project timing and destination. Distinguish the date you need a quotation from the date you need the parts delivered.

If a material, dimension or inspection requirement is unresolved, label it clearly. Ask the supplier what additional information is needed for technical review.

Checklist for preparing a comparable RFQ

These are the core areas covered by the Steel Founders’ Society of America’s purchasing guidance. Add the requirements specific to your component rather than treating a general checklist as its final specification.

Make the drawing and delivery scope clear

Identify which file controls the requirement when a drawing, model and written specification are supplied together. Mark critical dimensions, datum references, tolerances and surfaces to be machined. SFSA’s ordering guidance highlights these drawing details as part of the information needed to order steel castings.

For a replacement part, describe the interfaces with the existing equipment. Available drawings, photographs and measurements may support an initial discussion, but photographs alone should not be treated as a complete production definition. Ask the supplier to identify what must be confirmed.

Use explicit delivery descriptions:

• Casting blank: identify the required casting condition and which later operations the buyer will arrange.
• Rough-machined casting: list the operations included and the stock or features remaining for final machining.
• Finished component: define the finished dimensions, tolerances, interfaces and agreed verification records.

For example, a girth gear enquiry should identify whether the requested scope includes the casting segments only, joint machining or finished tooth machining. That distinction belongs in the quotation response, not only in a later conversation.

Specify the material and inspection requirements

Include the complete material designation and applicable standard edition, together with project requirements for heat treatment and tests. If the material is not yet selected, provide the application and service conditions for review. Any proposed substitute should be identified separately and approved by the responsible purchaser or engineer.

Inspection instructions need more detail than “good quality” or “NDT required.” Where applicable, specify the method, inspection area, coverage, acceptance criteria, inspection stage and required report. Define any third-party witness or hold points that the supplier must allow for.

These requirements should follow the component’s governing specification and service needs. SFSA’s steel casting specifications guidance explains why clear specifications are important for communicating material and inspection requirements.

Add practical information for a heavy component

A large part also needs a workable handling and delivery plan. Give the supplier the receiving location and any known limits on access, unloading or site handling. Ask which dimensions and weights are preliminary and which will be confirmed for shipment planning.

When requesting delivered pricing, identify the delivery rule, named place and applicable edition, and ask what freight, packing and handling services are included. Keep the quotation deadline, production schedule, shipment date and site arrival requirement as separate fields.

Tell the supplier whether an existing pattern can be made available and whether sample approval is required before further production. For a repeat project, explain what has changed since the previous order instead of relying on an old part number alone.

Ask each supplier to return the same information

Attach a short response checklist to the RFQ. Ask each supplier to state:

• The drawing revision and specifications used for its quotation.
• Included casting, heat-treatment, machining and inspection scope.
• Tooling charges and any conditions relating to existing patterns.
• Documents included with delivery.
• Schedule assumptions and the starting point for the quoted lead time.
• Packing and transport scope.
• Exclusions, deviations and technical questions.

This creates a practical comparison before commercial negotiation. For instance, a casting-blank price and a finished-component price should first be reconciled to the same scope. Record the difference rather than interpreting the lower total as an automatic saving.
