30CrMnSiA alloy steel plate shall be delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment state, and the delivery state shall be indicated in the contract.
30CrMnSiA alloy steel plate has high strength, but it belongs to medium carbon quenched and tempered steel, which has great hardenability. Therefore, the weldability of 30CrMnSiA alloy steel plate is very poor.
After quenching and tempering, the material has high strength, enough toughness and good hardenability. After tempering, 30CrMnSiA alloy steel plate can be used as grinding wheel shaft, gear and sprocket. If a tool is made, rough machining becomes the shape of the tool. 30CrMnSiA alloy steel plate quenching and tempering treatment method, using carbide milling cutter to mill the blade, polishing machine polishing. There should be no problem with a surface roughness of 3.2. The color of the material is gray. Galvanizing is not only for beauty, but also for rust prevention.
