There are three main   types of rails . Double headed rails, bull headed rails and flat footed rails. You will come to know all the important details of each of them with figures in the blog.   Let's start at the beginning. What are rails?   What are Rails? Rails are an important part of railroad tracks. They are rolled sections of high carbon steel, laid in two parallel lines end to end above sleepers, providing a continuous and horizontal surface for trains to move and carry the axle loads of rolling stock.   Let's take a closer look at the types of rails.  Heavy Steel Rail The main types of rails There are mainly 3 types of rails.   1. Double headed rails Double-headed  rails  indicate the early stage of development. It basically consists of three parts, such as the upper table, Web and the following table. The upper and lower tables are the same, and they are introduced in the hope of doubling the life of the guide.   When the upper table was used up, the armrests could be

Properties and Usages of Spring Flat Steel

Spring steel,   commonly referred to as annealed spring steel, is a so-called "universal" steel. Because of the wide range of uses and applications for this metal, Mead Metals offers a wide variety of spring steel products. Properties of Spring Steels Spring steel is known for its high yield strength, elasticity and flexibility. It has unique forming, shaping and post-treatment capabilities. These physical properties make spring steel a versatile steel.  Three types of annealed spring steels are available, which are distinguished by their carbon content. AISI 1050 has the lowest carbon content, making it easy to form. It can also be heat treated to increase hardness. AISI 1074 and 1075 have a medium carbon content spheroidized to increase their formability and can be heat treated. AISI 1095 has the highest carbon content of any spring steel we carry. It can be heat treated and has the highest elasticity and fatigue values.  Common spring steel products As a general purpose st
