Low-carbon alloy pellets (national patent ZL2013103780890) have high hardness (also can reduce hardness) and add a trace amount of chromium and molybdenum elements, which makes its metallurgical structure tight, with few internal defects, with high toughness and resilience,no crushing and impact resistance during use,has a long cycle life, shorten the cleaning time, improve the efficiency and reduce the cost, using the American Irving fatigue machine to make the cycle life (s460) 2800-3200 times, the comprehensive comparison of the amount of reduction than international steel shots by 50%, especially High hardness work (crankshaft, gears, leaf springs, etc.) has a more pronounced surface strengthening effect.
