ABSTRACT:
In a high pressure fuel injection pipe, pipe extension and heat treatment are repeated by using a header manufactured by transformation induced plastic type strength steel. A process for depositing residual austenite is then performed, after which a final pipe extension process is performed, and the joint portion is molded and bending processing is performed without performing perfect annealing at the size of a product.
