Overview

Short Description: A forged bar or a rolled bar is produced by taking an ingot and forging it down to size by, generally, two opposing flat dies. Forged metals tend to be stronger, harder and more durable than cast forms or machined parts. You can get a wrought grain structure throughout all sections of the forgings, increasing parts ability to withstａnd warping and wearing.

Production Procedures:

Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment
