Guangzhou Steel Ball S390 has uniform particle size, good toughness, high cleaning efficiency, and is an Anlan Di brand

Description :

　　Main technical requirements and specification levels for high carbon steel shot: S400~S030; Microhardness: 390HV-530HV; Chemical composition: Carbon: 0.8% -1.2%, Manganese: 0.6% -1.2%, Silicon: 0.4% -1.2%, Sulfur, Phosphorus: ≤ 0.05%; Metallographic structure: tempered martensite or tempered martensite; Density ≥ 7.0g/cm3; The total number of defects is ≤ 10%; Foreign impurities ≤ 1%; Moisture content ≤ 0.2%. The original standard GB6484-86 for cast steel shot was abolished in 1993. Due to the uniform blue color on the surface of tempered iron balls after annealing, they are often used to impersonate cast steel balls. The service life of iron balls is only 50-400 times, and the rust removal effect of iron balls is seriously reduced, which seriously damages the interests of users. The chromium molybdenum steel shot and manganese steel shot in other markets are all promotional concepts of manufacturers, because if 1% molybdenum metal is added, an additional 10kg of molybdenum metal is required per ton of steel shot, which exceeds the intrinsic value of one ton of steel shot and therefore does not conform to market trends.
