Feature
17Cr3 (1.7016) alloy structural steel strength and higher 15Cr steel hardenability, toughness is poor; welding is better, generally without heat treatment after welding.

This is a common low-alloy structural steel in carburization can significantly increase the surface of the carbon content, increasing the carburizing depth, but a long time at high temperature when carburizing tendency to grain growth and the formation of carbide network tendency; of simple shapes, less demanding parts, the direct cooling after carburizing quenching, but the large deformation after heat treatment, another temper brittleness of steel hardenability of high carbon steel compared with 15 in critical oil hardenability diameter of 2 ~ 15mm, the critical quenching in water diameter 6 ~ 29mm. In addition, the shaping of high cold deformation of steel, good weldability, in the annealed condition can be very good machinability.
