Product Description
Handan Shi Hengong Metallurgical Machinery Co.,ltd owns seven horizontal continuous cast iron production line ,that can produce Ductile/grey/alloy cast iron solid bars.The standard with HT 200,HT 250,HT 300 and QT400-18,QT 450-10 ,QT500-7 ,QT 600-3 .We can freely cut for customer.cut length are 1m,2m,3m and so on.
Materials Advantage:
Compared with other special steel,Hengong Bars has a lot of superior Characters as below:
1.With particularly pure material,without defects such as slag inclusion,sand inclusion and air holes
2,High comprehesive mechanic,especially with the notable raise for the character of tyhe toughnedd and the fatigue resistance .
3. Homogeneous structure,excellent pressure resistance and compactness.
4.The material with high precision,less maching allowance,high smooth finish surface for the maching.
5,Hollow section with all the above advantages,however with the higher density uniformity,as long as the pressure resistance and compachness
