Product Description
The alloy pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as oil, natural gas, gas, water and some solid substances. Compared with solid steel such as round steel, alloy steel pipe is lighter with the same bending strength and torsional strength. Alloy steel pipe is a kind of economic profile, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding for construction. The use of alloy steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, and save materials and processing time, such as rolling bearing rings, jack sleeves, etc. At present, steel pipes have been widely used in manufacturing. Alloy steel pipe is also an indispensable material for various conventional weapons. The barrel and barrel are made of steel pipes. Alloy steel pipes can be divided into round pipes and special-shaped pipes according to their sectional area and shape.

Low-carbon carburized steel with high manganese content (WMn 0.70%. 1.00%) has slightly higher strength, plasticity, machinability and hardenability than 1015 steel due to its high manganese content. There are less soft spots formed on the surface during carburizing and quenching, so carburizing and carbonitriding treatment should be carried out to obtain comprehensive properties with wear-resistant surface and good toughness at the core. Good toughness after hot rolling or normalizing. Apply to gears and crankshafts. Supports, hinges, screws, nuts, riveted structural parts. |
| 1019/1022 |
Characteristics and scope of application: high manganese low carbon penetration steel, with properties similar to 1016 steel. Low-carbon carburized steel with high manganese content (W mn 0.70% - 1.00%) has higher strength, plasticity, machinability and hardenability than 1015 steel due to its high manganese content. There are less soft spots formed on the surface during carburizing and quenching, so carburizing and carbonitriding treatment should be carried out to obtain a comprehensive performance with wear-resistant surface and good toughness at the core. Good toughness after hot rolling or normalizing. It is applicable to gears, crankshafts, brackets, hinges, screws, nuts, riveted structural parts, manufacturing oil tanks, etc. |
