STABILIZER STEEL HAVING HIGH STRENGTH AND EXCELLENT CORROSION RESISTANCE, VEHICLE STABILIZER EMPLOYING SAME, AND METHOD FOR MANUFACTURING SAME |
摘要 |
A steel has a predetermined chemical composition with a balance being Fe and incidental impurities, wherein a sum of Cu content and Ni content is 0.15 mass% or more, and a crystal grain size after forming into a stabilizer shape and quenching is in a range of 7.5 to 10.5 in prior austenite crystal grain size number. Thus, a highly durable stabilizer steel that has a tensile strength of 1200 MPa or more and excellent normal-temperature and low-temperature toughness and is used in an environmentally friendly manufacturing process at lower cost can be realized. |
