    Product Detail
  1. Technical Index
(1) Chemical Component:
C: 0.8 ~ 1.2%
Mn: 0.1 ~ 0.8%
Si: 0.1 ~ 0.6%
Cr: 0.8 ~ 1.7%
S: ≤ 0.03%
P: ≤ 0.03%
(2) Average Hardness:
The hardness of the 90% particle measured is within the following range:
Shot: 449 ~ 620HV(45 ~ 54HRC)
620 ~ 889HV(54 ~ 63HRC)
Grit: 449 ~ 620HV(45 ~ 54HRC)
620 ~ 889HV(54 ~ 63HRC)
(3)Metallographic Structure:
The alloying cementite wear-resistant phases with higher hardness is embedded in the matrix of martensite
(4) Service Life:
Under the same hardness, its service life is more than 100% of the one of high-carbon cast steel shot (grit) and 3 times of the one of white iron cast steel shot (grit).

2. Application Scope:
(1) The surface phase and shot blasting in high-hard casting, die-casting fitting, forging and heat treated parts
(2) The shot blasting and peening in high-hard casting, die-casting fitting, forging, heat treated parts, rolled steel, steel plate, shape steel and steelwork
(3) The pretreatment and treatment before coating of military equipment such as the submarine, and the aerospace and aeronautic equipment and
(4) The stone cutting
