The selection of stainless steel materials, thickness and width design for cylinder gaskets are centered around three core requirements: sealing reliability, temperature and pressure resistance, and compatibility with engine structure. Specific requirements need to be combined with the engine type，here are some perspectives to consider:
1.What are the common stainless steel material models for cylinder gaskets?
Cylinder gaskets are mostly made of stainless steel as the core layer substrate and require a sealing coating. Commonly used materials include 304 (ordinary naturally aspirated vehicles, moderate cost and high temperature resistance), 316 (supercharged/diesel engines, strong corrosion resistance), 430 (low-end models, low cost) and special alloys (racing cars, extremely high temperature resistance)..
2.What thickness of stainless steel coil is suitable for cylinder gaskets?
There is no unified standard for thickness, and it needs to be adapted to the seal compensation, compression ratio and working conditions: 0.5-1.5mm for ordinary naturally aspirated passenger cars, 1.2-3.0mm for commercial vehicles/diesel engines, 0.8-2.0mm for turbocharged engines, and 0.3-4.0mm for modified racing cars. The total thickness needs to be controlled for multi-layer structures.
3.What are the width requirements for stainless steel coils in the production of cylinder gaskets?
The width is completely based on the original factory design and must cover the combustion chamber cylinder port (over 2-5mm on one side), coolant water jacket (over 3-8mm), and lubricating oil channel (over 2-4mm), while avoiding structural interference such as bolt holes. It cannot be replaced at will and must strictly match the engine model. During installation, attention must also be paid to the synergy between torque and material coating.
