Detailed Product Description: | Handan City, specializing in the production of standard fasteners day vertical roller, roller frame, lifting lugs, connecting piece, nylon ground roller. Mass production of vertical roller, roller frame, lifting lugs, connecting piece, nylon ground roller, price, standard fasteners, Ltd. Handan City days to provide you with the vertical roller, roller frame, lifting lugs, connecting piece, nylon ground roller The latest price quotes for merchants to provide the most valuable vertical roller, roller frame, lifting lugs, connecting piece, nylon ground roller information. Roller stamping housings: Idler housings divided into two types, one is stamping bearing, the other one is cast iron (gray iron) bearing. Most stamping bearing and steel welding using cast iron and steel housings are made of extruded. Stamping housings characteristics are sealed roller technical literature, to withstand strong overall, the biggest feature cast iron housing is high concentricity, but lower than the stamping bearing endurance.

Beneficial elements manganese steel, silicon, vanadium, titanium, etc., can be controlled incorporation into low-alloy steel smelting. The main steel harmful elements sulfur, phosphorus and oxygen, pay special attention to control its content. Phosphorus is one of the very harmful elements in steel roller accessories wholesale, mainly soluble ferrite from strengthening. Phosphorus content increases, the strength of steel, hardness, ductility and toughness decrease significantly. Especially in the lower temperature, ductility and toughness on larger, significantly increasing cold brittleness of the steel. Phosphorus also can significantly reduce the steel weldability, but phosphorus can improve wear resistance and corrosion resistance of steel. Sulfur is also harmful element, showing the presence of nonmetal sulfide inclusions in the steel, the reduction of various mechanical properties of the steel. Because of the low melting point of sulfur, separating the steel grains caused during thermal processing, causing fracture of steel, the formation of thermal embrittlement, called hot brittleness. Sulfur steel weldability, toughness, fatigue resistance and corrosion resistance etc. is reduced. Oxygen is harmful elements in steel, mainly in the non-metallic inclusions, a small amount of melted in ferrite. Reduced mechanical properties of the non-metallic inclusions in steel, particularly toughness. Oxygen has a tendency to promote the role of aging. Low melting point oxides are caused weldability of the steel is deteriorated.
