Jis E 1101 Pdf -

A standard profile features a distinct head-web-foot geometry. For instance, a typical 50N rail utilizes an optimized height of 153 mm to maximize its section modulus and distribute extreme wheel loads without compromising structural elasticity. 3. Metallurgical Composition and Mechanical Properties

The 60N rail profile, defined in JIS E 1101, is used on all high-speed lines. Its optimized head radius reduces contact stress between wheel and rail at speeds exceeding 300 km/h. jis e 1101 pdf
