Hot rolled Dia 30-90 mm steel grinding balls

Description

Hot rolled steel ball Introduction

1. Producing standard: GB******8 and forging (rolling) ball ferrous metallurgy industry standardsYB/T*******5

2. Diameter: *****0mm

3. Raw material: *5# (S*5C, ***5), B2

4. High whole hardness: the surface hardness could be HRC****7

                                        the average volumetric hardness could be HRC****4

5. High notched .bar impact strength: More than *2J/cm2 

 

Hot rolled steel ball advantage:

The quality of hot rolled steel balls is stable, the hardness is uniform, the metallographic structure is compact, the impact resistance is good, the toughness is strong, the wear resistance is good, and the steel balls are not easy to crush and out of round.

 

Hot rolled steel ball specification:

1)Low breakage

2)keep good roundness 

 

3)high hardness

 

4)stable performance

 

5)longer life span

 

6)cost-effective
