Steel makes a huge contribution to the world's transportation. High-speed rail runs through north-south and east-west, railway connects you, me, and others. Railway transportation makes the economy take off.
1. The world's trains run on more than 1 million kilometers of steel tracks.
2. Steel will become the core component material of the world's fastest train "Super Steel", which will travel at a speed of more than 1,000 kilometers per hour. Lower cost than traditional high-speed rail.
3. As more advanced production technology produces longer rails, the journey becomes faster, smoother and quieter.
4. The Beijing subway transports nearly 4 billion passengers every year.
5. The world's longest St Ghedda Tunnel is made of 18,000 tons of steel.
6. The length of the world's railways exceeds 1 million kilometers, which is almost three times the distance to the moon.
7. Tunnel boring machines are steel industrial behemoths that make it possible to dig tunnels.
8. Corrosion-resistant high-strength stainless steel is used to make train carriages.
A588Grade A is a better weathering steel.
ASTM A588 Grade A atmospheric corrosion resistant steel plates have been used in a variety of applications, such as air preheater, economizer, railway carriage, containers production, bridge building , construction and so on.
