Emission Control System

About Emission Control System

In advanced vehicle design, the quality and performance of emission control components are fundamental to achieving regulatory compliance, environmental sustainability, and long-term system durability. The materials used in critical aftertreatment parts—including catalytic substrates, corrosion-resistant alloys, and specialised coatings—must exhibit exceptional thermal stability, chemical resistance, and structural integrity under corrosive exhaust conditions.

Key materials such as stainless steels, aluminium titanate, and nickel-chromium alloys are essential for manufacturing catalytic converter housings, Diesel Particulate Filter (DPF) substrates, Selective Catalytic Reduction (SCR) systems, and exhaust manifolds. Various catalyst washcoats and protective surface treatments serve as vital enablers to maximise catalytic conversion efficiency and mitigate degradation. These materials ensure optimal exhaust flow, stable catalytic activity, and overall system reliability in meeting the stringent demands of automotive and industrial emissions standards.

Why Choose SAM for Emission Control System?

At Stanford Advanced Materials (SAM), we specialise in supplying the high-performance materials essential for advanced emission control manufacturing. Leveraging our expertise in corrosion-resistant metallurgy and high-temperature engineering, supported by a portfolio of specialised alloys, ceramics, and catalyst support materials, we partner with manufacturers to develop aftertreatment solutions that deliver durability, conversion efficiency, and regulatory compliance for automotive and industrial applications.

Key Advantages

Extensive Portfolio for Harsh Exhaust Environments

We offer a selection of materials engineered for demanding aftertreatment applications, including heat-resistant stainless steels, nickel-chromium superalloys, aluminium titanate ceramics, and specialised catalyst support materials. These are foundational for manufacturing durable catalytic converter housings, Diesel Particulate Filter (DPF) substrates, Selective Catalytic Reduction (SCR) systems, and exhaust manifolds.

High Purity and Chemical Stability for Corrosive Conditions

All our materials are produced to achieve exceptional purity and batch-to-batch consistency, ensuring minimal impurities that could degrade catalytic activity or accelerate corrosion in aggressive exhaust flows. This guarantees predictable fabrication behaviour, reliable long-term chemical stability, and sustained emission control performance.

Optimised for Advanced Aftertreatment Manufacturing

Our materials are tailored for specific emission control manufacturing techniques. Our metal alloys are engineered for precise forming and welding, while our ceramic substrates and coating materials are designed for uniform cellular structure and catalyst washcoat adhesion, ensuring optimal results in high-volume production.

Thermal and Structural Integrity Under Cyclic Stress

Our products are selected for oxidation resistance, thermal shock resilience, and mechanical strength at elevated temperatures. This ensures reliable containment of exhaust gases, maintains component dimensional stability during repeated thermal cycles, and supports the overall durability and safety of the emission control system.

Customisation for Specific Aftertreatment Technologies

We provide tailored material solutions to meet unique design and regulatory challenges. Whether adjusting alloy composition for specific corrosion resistance in SCR systems, developing specialised coatings for sensor protection, or engineering substrate porosity for optimal filtration and back-pressure, we collaborate to support precise application goals.

Quality Assurance and Regulatory Compliance

All materials are produced under stringent quality control systems, ensuring full traceability and documentation. Our processes and products support compliance with international automotive emission standards (such as Euro 7, EPA Tier 4), aiding clients in meeting rigorous environmental, safety, and certification requirements for global markets.
