This guide provides general procurement information. The approved drawing, material standard, quotation and purchase specification control each order.
Key purchasing point
“Forging quality billet” should be treated as an application requirement, not a complete material specification. The purchase order must define the steel grade, standard, dimensions, condition, inspection method and acceptance values.
What makes a billet suitable for forging?
Suitability depends on the intended forged component and production route. A billet for a gear, shaft or automotive component may require different chemistry, cleanliness, surface acceptance, internal soundness, reduction practice and heat-treatment planning. The approved drawing and purchase specification should control the order.
| Requirement | What the buyer should provide |
|---|---|
| Material | Grade designation, governing standard and revision. |
| Dimensions | Square size, cut length, tolerance and quantity. Published square sizes are 80 × 80, 100 × 100, 125 × 125 and 160 × 160 mm. |
| Forging route | Component type, heating and forging process, reduction plan and final heat treatment. |
| Acceptance | Surface condition, internal-soundness requirement, inspection method and acceptance level. |
| Evidence | Chemistry, mechanical tests where applicable, heat traceability, MTC and third-party inspection needs. |
Surface quality and internal soundness
Visible surface condition and internal quality are different acceptance areas. If ultrasonic testing, macro examination or another method is required, state the test standard, technique and acceptance level rather than requesting a general “UT passed” billet.
Information required for a quotation
- Steel grade and applicable standard
- Square size, length, tolerance and quantity
- Forged component and downstream manufacturing route
- Supply condition and heat-treatment plan
- Surface and internal acceptance requirements
- Traceability, MTC and delivery destination

Frequently asked questions
What is a forging quality steel billet?
It is a billet ordered for a defined forging application with an identified grade, standard, dimensions, condition, inspection scope and acceptance criteria. The phrase alone is not a complete specification.
Which forging billet sizes are published?
Published square sizes are 80 × 80, 100 × 100, 125 × 125 and 160 × 160 mm. Grade-size-condition availability is confirmed for each enquiry.
What testing should be stated?
State the governing test standard, method and acceptance level for chemistry, mechanical properties, surface quality, internal soundness, traceability and certification as applicable.
What details are required for a quotation?
Provide grade, standard, square size, length, quantity, forging application, supply condition, testing, documentation and delivery destination.
