What is the chemical composition of SPA-C railway steel?

Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel SPA-C railway steel and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

The types of carbon steel are basically as the following: SPA-C railway steel, Carbon structural steel, which is mainly used in various projects. High-quality carbon structural steel, whose main purpose is for important parts. Carbon tool steel, which is mainly used to make various small tools. Cast carbon steel parts for general engineering, which are mainly used for complex parts that are difficult to form by forging and other methods and require high mechanical properties.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, SPA-C railway steel, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. SPA-C railway steel, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.

SPA-C railway steel, 15CrMo alloy steel is Chinese material. It is characterized by high Chrome and Molybdenum contents. The 15CrMo alloy steel chrome content is 0.80-1.10, and molybdenum content is 0.40-0.55. Besides, 15CrMo carbon content is 0.12-0.18, silicon content is 0.17-0.37, manganese content is 0.40-0.70. The heating temperatures for quenching and tempering of 15CrMo alloy steel are 900 and 650 centigrade respectively. The yield point of 15CrMo alloy steel is 295Mpa.

The automobile steel coil and sheets are one of our main steel materials exported to the overseas.
