Katahi ka riro te rino ki te wai, ki te hinu ranei, hei mea kia hohoro, a ka puta ke te rinena hei rinenaThe rapid cooling during heat treatment will cause thermal stress in the product workpiece, and when it is large to a level, the product workpiece will be distorted and deformed. Pupuri.Koia i whakamatautau ai kia whiriwhiria te huarahi whakakai tika
E tahuna ana e te puarahi o Q345B, kahore nei e taea te puarahi, ko te puarahi o te hua o te hua o te mea parahi ki tetahi wahi o te temperatura e taea ana e ia kia taea noatia te wa e taea ana, ka tomo tonu ki roto ki te mea e tineia ana.Ko te whakaoho hohoro o te paihere o te paihere o te whakamatautau i te paihereKo nga mea e tineia ana, he wai, he minerala kei rotoNgā hinu motoro, gāzu, etc.
He aha te whakakaha ai i te kaha, te kakahuria ai e koe te whakakaha o nga mea parahi, he mea whakakakahuria ai te werawera, he mea whakarihariha ki te whakamahi i nga mahi katoa, i nga parahi, ki te whanganga i nga mea whanganga, i nga mea whanganga me te mata kara, he mea whakakakahuria ai nga mea parahiI muri i te werawera atawhainga, i te tineia i te temperatura whakaharahara, he aha kihai i nui rawa te whakanekehia i te kaha, i te pakeke, i te whakamamae o nga mea metali, kia whiwhi ai ki nga whakamamae o enei mohiotanga kia tutuki ai ki nga kara whakaharahara o te mahi
In addition, the heat treatment of the Q345B seamless square tube can also make some grading steels have physical effects, such as heat treatment to improve the ferromagnetic material of the rare earth permanent magnet steel, and the corrosion resistance of the stainless steel plate.
He pātuhi tērau e rua ana whakatakotorangaE tika ana te whakatakotoranga o te whakatakotoranga he whakatakotoranga.I aha koe ki te tokorua?Ki te mea he tērau i whakaahuatia e ahau, ka marama tonuNo te mea i te whakawhitinga
