Product Features:
● Moderate hardness, strong toughness, large impactSteel Shot: Steel Shot made of special steel combined with more than 20 years of production experience, using advanced tempering process and special heat treatment.
Features:
● Moderate hardness (HRC40-50) good resilience
● Strong toughness, impact resistance, long service life
● Low loss, fast cleaning speed
● Good cleaning effect - metal surface cleanliness of GB/T8923-1989, roughness of 10-150um
Steel shot application: Steel shot is widely used through shot blasting machines in the sand cleaning of casting parts. Forging, steel structure, steel workpiece rust strengthening, removal of oxidation, surface pretreatment before coating, sand cleaning, pipe descaling, strengthening and other industrial fields, is a high-quality shot blasting cleaning medium.
Production standards: Steel Shot is produced in strict accordance with the United States SAEJ444,SAE J827 cast steel shot standards
