He pakoko pakoko i runga i te puranga o te turanga o te pihi i Q345B, he pakoko taimaha, he pakoko taimaha i runga i te pakoko.He nui atu te mahi a te putanga o Q345B i te putanga karere i te putanga o Q345B karere.Q345B seamless square tube has higher precautions and knowledge under high temperature. Her stres relaxation compressive strength and long-term compressive strength, long-term operating temperature reaches 500 °C;He hanga plastika i te matao i te turanga matao kei te pakoko pakoko, a he rawakore te kaha o te atawhaiI rite ki nga mea papai o te mahi i raro i te taimaha roa, ki nga mea whakarewaina o te karere, o te motuhi dierethe motor rotor of the steam turbine, the main shaft bearing, the heavy-load rotating shaft, and the large cross-section parts.
He pai rawa te mahi i te tērau.I muri i te whakauru, i te hanganga, ka whakaititia nga whakapaipai o te kohua, me nga mea whakarewainaAfter the heat treatment process, the surface strength can be improved and the mold shell'e taea te ora o te mahi kia pai.I mua i te whakamatautauranga mahana, ka whakanekehia te tineia, te tineia raneiRite tonu ki te kristale pai rawa, ka nekehia atu te hanganga e rite ana ki te kupenga o te feriri, me te hanganga o te paruE taea e te Q345B tūpu karere te whakanekehia ake te whārangi o te whārangi whārangi
He kaha pakeke rawa te rino o nga puranga turanga, he pakeke rawa, he kaha pakeke rawaHe nui atu te mahi tapahi i te tērau tiro i Q345B.Yüksek stres relaxation gücü ve uzun süre compression gücü yüksek te
