Ukuthengiswa kwewaranti ye-30CrMo yomenzi wepayipi yensimbi ye-alloy
I-16Mn i-alloy low-alloy high-forth-structural iron: umxholo wekhabhoni ngu-0.1% - 0.25%, kunye nezinto eziphambili ze-alloy manganese, i-silicon, i-vanadium, i-niobium kunye ne-titanium yongezwa; Umxholo wayo opheleleyo we-alloy ungaphantsi kwe-3%. Ngokwamandla, ihlukaniswe ngamanqanaba amane: 300, 350, 400 kunye ne-450MPa. Kukho ubukhulu becala q295, Q345, Q390, Q420 kunye ne-Q460 "Q" yi-Chinese Pinyin capital prefix yegama elithi "Qu" elivelisa, kwaye inani elilandelayo lelona ndawo lisezantsi lesivuno sophawu (σ s) Iimpawu ezilandelayo zi yahlulwe ibe yi-a, B, C kunye no-d ngokomxholo wezinto ezingcolileyo (isulfure kunye ne-phosphorus) kwintsimbi ukusuka phezulu ukuya ephantsi kunye nokutshintsha kwekhabhoni kunye ne-manganese. Phakathi kwazo, iintsimbi zeBanga A kunye ne-B zihlala zibizwa ngokuba yi-16Mn.
Ngokwamandla, ihlukaniswe ngamanqanaba amane: 300, 350, 400 kunye ne-450MPa.
Kukho ubukhulu becala q295, Q345, Q390, Q420 kunye Q460.
16Mn umbhobho wentsimbi ongenamthungo
16Mn umbhobho wentsimbi ongenamthungo
I-16Mn umbhobho wentsimbi engenamthungo luhlobo lwemathiriyeli. Umbhobho wentsimbi ongenamthungo wawukade ubizwa ngokuba ngumbhobho wentsimbi ongenamthungo.
Indlela yangoku yile: Q345B umbhobho wentsimbi ongenamthungo. Izinto ezifanayo ziyi-Q345C, i-Q345D kunye ne-Q345E. Isimboli yebakala lomgangatho a, B, C, de ibonisa iimfuno ezahlukeneyo zovavanyo lwempembelelo. Ubushushu bovavanyo lwempembelelo + 20 ° 0 ° ukuya ku-20 ° 40 ° ngokulandelelanayo. I-16Mn yimpahla yombhobho wensimbi engenamthungo.
I-ABCD ibonisa umgangatho webakala Q235. Ibanga lomgangatho lahlulwe ngokwamabanga amane A, B, C no D. ukusuka ku-a ukuya ku-D libonisa umgangatho ukusuka kweliphantsi ukuya phezulu.
Iimfuno zamanqanaba ahlukeneyo omgangatho zezi zilandelayo:
A - ukubonelela s, P, C, Mn, Si chemical composition and Fu, FY δ 5 ( δ 10) , 1800 uvavanyo lokugoba olubandayo lunokubonelelwa ngokweemfuno zomthengi, kodwa akukho mpembelelo yokulawula amandla, kunye nomxholo wekhabhoni. kunye nomxholo wemanganese awuthathwa njengemiqathango yokuhanjiswa.
B - ukubonelela s, P, C, Mn, Si chemical composition and Fu, FY δ 5 (δ 10) , i-gold bend 180 'test. Ikwabonelela ngamandla empembelelo AK ≥ 27j kwi + 200C - ngaphezu kweemfuno zeklasi B, inika kwakhona amandla empembelelo AK ≥ 27j kwi-00C.
C - ngaphezu kweemfuno zenqanaba B, amandla empembelelo AK ≥ 27j kwi-200C nayo inikezelwa. E -- ngaphezu kweemfuno zenqanaba B, amandla empembelelo AK ≥ 27j kwi-400C nayo inikwe.
