20Cr alloy steel pipe has hollow section and is widely used as pipeline for conveying fluid, such as pipeline for conveying oil, gas, water and some solid materials.

Compared with solid steel such as round steel, 20Cr alloy steel pipe has lighter weight when the bending and torsional strength is the same.

20Cr alloy steel pipe is a kind of economic section steel, which is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.

Manufacturing ring parts with 20Cr alloy steel pipe can improve material utilization, simplify manufacturing process, save materials and processing hours, such as rolling bearing ring, jack sleeve, etc.
