D49 piston 4-5D49.22 SPCH-05

Тип предложения / Предлагаю продукцию, услугу

1. In terms of D49 engine piston structure, due to the split structure, the steel top of the piston is designed as a self-supporting component, and the"drilling cooling"method is adopted to improve the rigidity and heat dissipation capacity of the piston head. The split piston structure adopts high-strength bolts, and the piston skirt adopts high-quality Grade A heat-resistant alloy steel.

2.In terms of materials, we uses high-quality A-grade heat-resistant alloy steel to produce D49 engine piston . From raw material procurement to processing to finished products, we strictly control and repeat the relevant parameters of the steel roof material in each link. detection.
