What is the processing method of our steel round bar?
Production technology process of product:
Check the raw materia→Blank → Grind the burr of blanked material → Heat in the intermediate frequency heating furnace → Align → Quench → Temper → Inspect → Package
What’s our steel round bar’s characteristics?
The characteristics of the wear-resistant steel bar are as follows:
1.Good mechanical properties:low abrasion,high hardness,strong toughness
2.Excellent wear-resisting property,long service life,reduce work force.
3.Size and specification are adjusted,the flexibility is greatly improved.
4.Improve the production efficiency,save cost,greatly increase production volume
