steel carbon pipe

Carbon steel is the carbon content of less than 2%, and a small amount of silicon, manganese and phosphorus, sulfur and other impurities in the iron-carbon alloy. Industrial application of carbon steel carbon content generally less than 1.4%. This is because the carbon content of more than this amount, the steel show a great deal of hard and brittle nature, and processing difficulties, loss of production and use value. Carbon steel can be classified according to their different masses ordinary carbon structural steel and high-quality carbon structural steel two categories. High-quality carbon structural steel provides sulfur and phosphorus content than ordinary carbon steel to allow low, so mechanical properties better than ordinary carbon steel.
(1) manufacturing methods. Carbon steel smelting usually BOF, open hearth furnace carried out. BOF General Smelting ordinary carbon steel, while the open-hearth can be a variety of high quality steel smelting. In recent years, oxygen BOF steelmaking technology has developed rapidly, there is a tendency to replace the open-hearth steel. The refining of molten steel into the ingot mold, get all kinds of steel ingot. After forging, or rolling ingot after processed into various shapes of steel and forgings. Ingot processed through the pressure, can improve the steel's internal organization and distribution of inclusions, so the same composition of the steel ingot in superior performance than some.
(2) purposes. Strength of carbon steel is mainly used to manufacture machine parts and a variety of less demanding metal structures. Widely used in machinery manufacturing in all its aspects. Such as agricultural machinery, machine tools, and ships. It is a most widely used, uses the largest steel.

Carbon content of less than 1.35%, in addition to iron, carbon and limited within the silicon, manganese, phosphorus, sulfur and other impurities, the steel does not contain other alloying elements. The performance of carbon steel depends on carbon content. Carbon content increased, the strength of steel, the hardness increased, plasticity, toughness and weldability decrease. Compared with the other steel type, carbon steel using the first, low cost, performance range, the largest amount. For nominal pressure PN
