The wave of AI computing power
The wave of AI computing power is driving the acceleration of data center construction, and diesel generator sets are experiencing a surge in rigid demand. In harsh operating environments, stainless steel dedicated to exhaust systems has become a core rigid demand. Relying on years of accumulation in stainless steel exhaust systems, Hexianda is seizing the long-term development opportunities in the diesel generator set sector.
01 Industry Trends
Computing power drives diesel generator sets into a golden era of development
Driven by the dual forces of the digitalization wave and the explosion of AI computing power, the construction of data centers worldwide has entered a phase of rapid growth. As a safeguard for power safety in data centers, diesel generator sets serve as the core standby power source in extreme power outage scenarios. Their rigid demand attributes in the industry continue to be highlighted, and a supply-demand transformation centered around standby power is reshaping the industrial landscape. Domestic leading power enterprises, represented by Weichai and Yuchai, have quickly seized the market with their technological advantages.
02 Essential Amenities
Diesel engine exhaust system imposes stringent requirements on dedicated stainless steel
Diesel generator set under long-term high load
Continuous operation under harsh exhaust conditions:
The temperature at the front end of the exhaust system is extremely high, and the exhaust gas contains sulfides and nitrogen oxides. The condensate water is highly acidic and corrosive, and the equipment operates with frequent vibrations. Therefore, the material requirements for components such as the exhaust housing, end cone, and heat shield are much higher than those for ordinary civilian applications.
Based on our company's extensive experience in the application of exhaust system materials over many years, the selection of dedicated stainless steel for various parts of diesel engine exhaust systems is clear and unambiguous:
Front exhaust housing/main pipe: 436L, 304 stainless steel
Close to the engine heat source, the temperature is high and the exhaust gas has strong corrosivity. 436L contains molybdenum, which has excellent high-temperature resistance and acid corrosion resistance; 304 austenitic stainless steel has full rust and oxidation resistance, suitable for high-end diesel engines and harsh environments, effectively avoiding shell rust penetration and weld cracking.
Rear end cone component: 409L stainless steel
Used for sealing the end of the muffler package and guiding exhaust gases, 409L is a heat-resistant steel specifically designed for exhaust systems. It is resistant to thermal fatigue and corrosion from condensed water, possesses strong toughness, and is shock-resistant and durable, ensuring structural stability of the exhaust system.
Oxygen sensing and exhaust gas detection end cone: 441 stainless steel
Stably control thermal deformation, ensure accurate oxygen content detection, and adapt to the China VI standard and the emission monitoring requirements of intelligent diesel engine equipment.
Heat shield: 304, 430 stainless steel
It features a thin profile, lightweight, and is easy to press and shape. It serves as a heat insulator, preventing burns, and also serves as a noise reducer and protector, safeguarding the surrounding wiring harness and components of the unit.
It can be said that dedicated stainless steel is the core basic material for the safe, stable, and long-term operation of the exhaust system of diesel generator sets.
