Selecting the right hot forging supplier is more than just comparing quotes or evaluating equipment capabilities—it’s about ensuring long-term reliability, safety, and quality. Certifications serve as a verifiable indicator that a supplier adheres to globally recognized standards for production, materials, and management. These credentials are necessary for sectors including aerospace, automotive, defense, and energy.
Below, we’ll explore the key certifications to look for, why they matter, and how they reflect a supplier’s professionalism and quality commitment.
Why Certifications Matter in Hot Forging
Hot forging involves heating metals—such as steel, aluminum, or titanium—to high temperatures before deforming them into precise shapes under immense pressure. This process improves mechanical properties like toughness, fatigue resistance, and structural integrity. However, the high temperatures and tight tolerances leave no room for error.
Certifications ensure that every step—from raw material procurement to final inspection—is performed under strict quality control and traceability systems. For customers, they guarantee consistency, compliance with industry regulations, and minimized risk of failure or rework. A certified supplier can also accelerate project approvals and reduce the need for repeated audits.
ISO 9001: The Foundation of Quality Management

For industries transitioning toward carbon-neutral supply chains, working with ISO 14001-certified suppliers can support broader ESG (Environmental, Social, and Governance) goals.
ISO 45001: Occupational Health and Safety
Hot forging workshops are high-risk environments—exposing workers to extreme heat, heavy loads, and moving machinery. ISO 45001 certification demonstrates that the supplier has a proactive system for minimizing occupational hazards and maintaining worker safety.
Why this certification is critical:
- Confirms adherence to international safety standards.
- Reduces accident rates and downtime.
- Ensures compliance with labor regulations and insurer requirements.
- Improves morale and retention among skilled forging operators.
Clients benefit indirectly too—suppliers with safe and efficient workplaces tend to maintain higher productivity and lower operational disruptions.
IATF 16949: Automotive Industry Quality Standard
The International Automotive Task Force created IATF 16949 certification, which is required if you are purchasing forged components for automotive applications. It builds on ISO 9001 but adds stricter controls tailored to the automotive supply chain.
Key focus areas:
- Product traceability across the production cycle.
- Statistical process control and defect prevention.
- Continuous improvement and risk-based thinking.
- Requirements for customer-specific standards and audits.
Many car manufacturers will not approve a supplier without IATF 16949 certification, as it directly correlates to safety, durability, and performance of critical parts such as crankshafts, connecting rods, and gear blanks.
AS9100: The Gold Standard for Aerospace Forging
For the aerospace sector, where a single defect can lead to catastrophic failure, AS9100 certification is indispensable. It expands on ISO 9001 by adding specifications unique to the aerospace industry for risk management, design control, and product traceability.
What AS9100 ensures:
- Strict control of raw materials (e.g., titanium, nickel alloys).
- Non-destructive testing (NDT) and metallurgical validation.
- Documentation traceable from billet to finished part.
- Compliance with regulatory authorities like FAA and EASA.
AS9100-certified hot forging suppliers are approved by top-tier aerospace OEMs and Tier 1 suppliers. This certification signals that the supplier’s processes meet the industry’s most demanding quality assurance systems.
ISO/TS 29001: Oil, Gas, and Energy Applications
For forged parts used in oilfield tools, drilling equipment, turbines, and pressure vessels, ISO/TS 29001 is the standard developed jointly by ISO and the petroleum industry (API).
Benefits include:
- Consistent control over material composition and mechanical properties.
- Documentation of forging and heat-treatment parameters.
- Prevention of material mix-ups and inclusion defects.
- Alignment with API standards such as API Q1 and API Spec 6A.
Choosing a supplier with ISO/TS 29001 helps energy companies ensure reliability in high-pressure, high-temperature environments where failures can have severe economic and safety consequences.
Nadcap Accreditation: For Aerospace and Defense Forging
Nadcap (National Aerospace and Defense Contractors Accreditation Program) is one of the most prestigious process-specific certifications. It’s required by major aerospace and defense OEMs (e.g., Boeing, Airbus, Lockheed Martin) for suppliers performing special processes such as heat treatment, NDT, or metallurgical testing.
Why Nadcap accreditation stands out:
- Independent verification of process control and equipment calibration.
- Detailed audit of forging, heat treatment, and inspection processes.

A Nadcap-accredited hot forging supplier signals world-class process consistency and compliance with stringent aerospace specifications.
PED and AD 2000: European Pressure Equipment Standards
For customers in the European Union, hot-forged components used in boilers, valves, or pipelines must comply with Pressure Equipment Directive (PED) 2014/68/EU. Suppliers can demonstrate this compliance through PED certification and often AD 2000-Merkblatt W0 for German markets.
PED/AD certifications verify:
- Material traceability and conformity assessment procedures.
- Control of mechanical and chemical testing.
- Qualification of personnel and welding/forging procedures.
- Documentation for CE marking.
Without these certifications, forged parts cannot legally be installed in EU pressure systems, making them essential for exporters to European markets.
