Stainless steel oil feeding pipe |
| 摘要 |
A fuel-filler tube, which is made of a welded pipe of corrosion-resistant austenitic or ferritic stainless steel, has a fuel-supply opening with high dimensional accuracy. The austenitic stainless steel has hardness of 180 HV or less with a work-hardening coefficient of 0.49 or less. The ferritic stainless steel has Lankford value of 1.2 or more with elongation of 30% or more by a uniaxial tensile test.
