30CrNiMo8 High Press Vessel Alloy Steel Forgings For Wind Power Shafts

Jiangyin Fangyuan Ringlike Forging And Flange Co., Ltd. lists model FY-0117 as a heavy-section alloy steel forging for gear shafts and applications described in the product title as high-pressure vessel and wind-power shaft components. The product page identifies a 50 kg–15,000 kg weight range, a maximum outside diameter of 1,000 mm, quenching and tempering (Q+T), and rough machining. Final material designation, product form, drawing dimensions and acceptance criteria should be confirmed in the approved order documentation.

• 50 – 15,000 kg Published forging weight range
• 1,000 mm Maximum outside diameter
• 20 – 45 days Published delivery time
• 6,000 t/month Company-stated supply ability

The following ranges are transcribed from the original listing. Confirm them against the ordered standard and the actual heat analysis on the material test certificate.

For a heavy-section alloy steel shaft or vessel forging, the manufacturing plan should connect the approved grade and section size with forging temperature control, deformation, heat treatment, machining allowance and inspection. The product page identifies Q+T and rough machining as its stated route.

Equipment quantities and capacities are transcribed from the product page; confirm current availability and actual work envelope for the drawing.

The following links provide product-page, supplier, video or visual context. They are not substitutes for material certification, inspection reports or contractual specifications.

• 1. Can FY-0117 be manufactured to a customer drawing?

  Submit a controlled drawing defining exact grade, standard, geometry, dimensional tolerances, machining allowance, heat-treatment condition, inspection points and marking requirements for technical review.

• 2. What is the minimum order quantity?

  The published MOQ is one piece. Confirm commercial terms against forging weight, raw-material availability, setup, heat-treatment batch planning, machining hours and inspection requirements.

• 3. How should 30CrNiMo8 and 4340 be specified?

  The product metadata says Alloy Steel 4340, while the title and detailed description focus on 30CrNiMo8 and related designations. Select one governing grade and standard in the purchase order and obtain written confirmation. Do not assume all listed designations are automatically interchangeable for every product form or specification.

• 4. Which mechanical properties and tolerances can be guaranteed?

  Specify tensile strength, yield strength, elongation, impact energy and hardness according to the ordered standard, section size and heat-treatment condition. Put dimensional tolerances on the approved drawing; do not transfer small-section reference values directly to a large forging without checking the applicable provisions.

• 5. Which inspection documents should be requested?

  Agree the material test certificate, heat-treatment record, chemical analysis, tensile and impact tests, hardness report and dimensional inspection report. Specify UT or other NDT methods, coverage, acceptance level and third-party witness points in the inspection and test plan.

• 6. How should the forging be packed for ocean freight?

  The listing describes seaworthy wooden cases, iron pallets or buyer-specified packing. Define corrosion protection, moisture barrier, machined-surface protection, anti-impact blocking, lifting points, lashing, package weight limits and external identification.

• 7. Is the delivery time fixed at 20–45 days?

  The listing publishes 20–45 days. Confirm the schedule after drawing approval, material procurement, forging, heat treatment, machining, inspection and packing are finalized, including the schedule start point and inspection hold points.

• 8. What after-sales support should be agreed?

  Set out non-conformance notification periods, evidence requirements, traceability records, corrective-action procedures, rework or replacement responsibility and technical-document support in the contract.

• Confirm the contracting legal entity and manufacturing site.
• Resolve 4340 versus 30CrNiMo8 designation before order release.
• Confirm standard edition, product form and chemistry limits.
• Approve drawing dimensions, tolerances, machining allowance and final condition.
• Specify mechanical tests, impact temperature, hardness and NDT criteria.
• Verify certificate holder, scope, covered site, product family and validity.
• Approve packing, corrosion protection, marking and shipping documents.
• Confirm lead-time milestones, inspection hold points and non-conformance remedies.
