Definitions
- the invention relates to a new steel grade of nickel-free high manganese steel with high strength and high toughness under low temperature
- B 7 steel C 0.50 to 0.62, Mn 0.50 to 0.80, Si 0.15 to 0.35, P ⁇ 0.045, S ⁇ 0.050, and Fe in equilibrium.
- the YW35 steel of the present invention is developed for fishtail plates for low-temperature rails. It is based on high-manganese steel, and when the carbon content is reduced, appropriate amounts of molybdenum and trace elements vanadium and niobium are added to improve the low-temperature performance of the steel. Applicable to the fish rails for railway parts and rails, which are growing in our country. Replacement page (Article 26)
- the YW35 steel of the present invention is a new steel type obtained through chemical composition design, smelting rolling and heat treatment process, and is characterized in that the chemical composition of the YW35 steel is (wt%):
- the shape of the low-temperature fish plate made of YW35 steel is a groove-shaped straight steel plate.
- the two sides of the steel plate are working surfaces with a slope of 1: 3, and the center of the groove is unequal. Distance round hole.
- the YW35 steel low-temperature fish plate of the present invention can be applied to joint steel plates for high-speed railway rails.
- YW35 steel is based on rhenium-manganese steel.
- molybdenum and trace elements are added: vanadium and niobium to improve the low performance of the steel.
- Figure 1 is a sectional view of the low-temperature fish plate of Y 35 steel. detailed description
- the YW35 steel of the present invention is a new steel grade obtained through chemical composition design, smelting, rolling and heat treatment processes. During the trial production, three groups of material formulas are formed according to the properties of the elements. The chemical composition of these three groups of formulas is (%) : (1), C 0.32, Mn 1.10, Si 0.30, P ⁇ 0.035, S ⁇ 0.035, M 0 0.15, V 0.06,
- reference numeral 1 is a low-temperature fish plate of YW35 steel
- reference numeral 2 is a round hole
- reference number 3 is a working surface.
- the side surface is the working surface 3
- the working surface 3 has an inclination of 1: 3
- the center portion of the groove is provided with circular holes 2 of different distances, which are process holes.
