The macroscopic characteristics of hardened steel with quenching cracks

Steel belt will experience a quenching process, heat treatment process which is hardened steel belt manufacturer must experience in manufacturing process, this process of steel strip after performance will change with the change of temperature, on the hardness and toughness of steel strip produced huge impact, but the process if not handled properly can appear some serious problems, such as steel strip surface quenching cracks. Quenching crack characteristics can be divided into macro and micro two kinds, today we mainly to understand the macroscopic characteristics of components of the stress concentration, and sometimes because of the part itself geometric shape, special parts, and the specific technical requirements, the influence of cooling rate produce a stress concentration area; Quenching crack generally begin bulky, tail small, there is no certain direction and the distribution regularity, local position will be cracked if the heating temperature is high; The depth and width of cracks and the size of the parts of internal residual stress has a direct relationship, the greater the residual stress in the quenching crack more deep and more wide, when quenching stress, exceeded the brittle fracture strength, result in the crack of the parts. So need special attention in the process of steel with heat treatment to temperature control, in order to prevent the occurrence of cracks events, hardened steel with the quenching crack characteristics on the onlookers analysis we will answer for you in the next update, if you want to learn more, remember to focus on our dynamic! A: on the characteristics of the strip steel quenching crack under a: hardened steel with the quenching crack of microscopic characteristics
