Delivery status
Delivery in heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment status, the delivery status should be specified in the contract.
It has high strength, but it is a medium carbon quenched and tempered steel with large hardenability, so its welding performance is very poor.
After tempering, the material has high strength and sufficient toughness, and has good hardenability. After quenching and tempering, the material can be used as grinding wheel shafts, gears, and sprockets. If you make a tool, rough it into the tool shape. Tempering treatment. Mill the blade with a carbide milling cutter and polish with a polishing machine. The surface roughness reaches 3. There should be no problem. The material is darker in color, and galvanizing is not only for aesthetics, but also for rust prevention
