Liaocheng Fengye Chemical Fertilizer Plant introduces 15crmo chemical fertilizer pipe knowledge
15CrMo fertilizer pipe is an alloy high pressure boiler pipe, alloy structural steel. Seamless steel tubes made of such steel are widely used in hydraulic props, high-pressure gas cylinders, high-pressure boilers, fertilizer equipment, petroleum cracking, automotive axle bushings, diesel engines, and hydraulic pipe fittings.
The composition of 15crmo chemical fertilizer pipe (GB/T3077-1999) is based on high-quality carbon structural steel, appropriate addition of one or more alloying elements, used to improve the mechanical properties of steel, toughness and hardenability. Products made of such steels are usually subjected to heat treatment (normalizing or tempering); the parts and components that they are made of are usually subjected to quenching or surface chemical treatment (carburizing, nitriding, etc.), surfaces before they are used. Quenching or high frequency quenching treatment. Therefore, according to the chemical composition (mainly carbon content), heat treatment process and the use of different, such steel can be roughly divided into carburizing, quenching and nitriding steel three.
This kind of steel multi-rolling (forging) made round, square, flat profiles and seamless steel pipe, used in the production of mechanical products more important and larger size of the zero, parts and high-pressure pipes, containers, etc., this high-quality carbon structural steel More excellent comprehensive mechanical properties.
