Chisel no3applying? 1. The length of moil point for paving breaker B47,Website:http://www.nbydtools.com, B67, B87 are 500mm, 550mm, 600mm.2?Pick brazing general materials is 55 simnmo now, using the 860 - degree heat, air cooling or fog LengZhengHuo processing, pick brazing is the main performance requirements of impact resistance toughness, also have a certain wear resistance, relative to other performance, impact toughness is the main contradiction, so using normalized processing, get granular bainite organization as the main target.
