Fuel accessories are high-precision components measuring 100x280x400mm, crafted from durable materials such as SKD11, SKD61, D2, SKS5, P20, DC12, and DH6. Engineered with an exceptional precision of 0.001mm and a hardness of HRC 58-60, these components are produced using advanced techniques including CNC machining, wire cutting, EDM, and deep hole drilling. To enhance their mechanical properties and durability, they undergo specialized surface treatments such as nitriding, carburizing, annealing, normalizing, quenching, and tempering. These processes ensure reliability and performance in demanding fuel system applications.
