P235GH ke lisebelisoa life? E lumellana le thepa efe Chaena?
P235GH ke ts'ebetso e phahameng ea mocheso oa Fihekin le pipe ea tšepe ea alloy, e leng tšepe ea Jeremane e nang le mocheso o phahameng oa mocheso. P235GH, EN10216-2 khatello ea phala ea tšepe e se nang seamless e lumellana le maemo a naha a 20G, 20MnG (GB 5310-2008 high-pressure boiler pipeless steel pipe).
Pipe ea tšepe ea P235GH alloy e se nang moroalo hangata e qhibilihisoa ka seboping sa motlakase sa arc le converter e bululetsoeng ka holimo oksijene. Bakeng sa litlhoko tse phahameng, e amohela ho hloekisoa ka ntle ho sebōpi, ho qhibilihisa sebōpi sa vacuum induction kapa smelting e habeli ea vacuum, electroslag remelting kapa vacuum treatment, le phekolo ea mocheso.
P235GH, EN10216-2 phala ea tšepe e se nang seamless e loketse ho etsa likepe tsa khatello le lisebelisoa tsa lisebelisoa. Ha ho bapisoa le tšepe e tloaelehileng, tšepe ea alloy ea P235GH e na le matla a phahameng le ho tiea, ts'ebetso e batang ea ho khumama le ts'ebetso ea welding, thepa ea lik'hemik'hale, ho lumellana ha lintho, thepa ea 'mele le ts'ebetso ea ts'ebetso.
Mechini ea thepa ea P235GH alloy steel pipe: tensile matla σb350 ~ 480 MPa; tlhahiso ea matla σs≥215 MPa; bolelele δ5≥ 25%; matla a ho monya matla Akv≥47 J; Boima ba Brinell ≤105~140 HB100
Sebopeho sa lik'hemik'hale (karolo ea boima, %) ea pipe ea tšepe ea tšepe ea P235GH: ≤0.16 Si; 0,60 ~ 1,20 Mn; ≤0.025 Kr; ≤0,30 Ni; ≤0,30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
Setšoantšo se latelang ke tafole ea papiso ea pipe ea tšepe ea P235GH le limaraka tse tšoanang tsa tšepe:

Phekolo ea mocheso ea P235GH phala ea tšepe e se nang moeli bakeng sa khatello: mocheso o chesang oa ho sebetsa 1100 ~ 850 ℃; mocheso annealing 890 ~ 950 ℃; normalizing mocheso 520 ~ 580
P235GH alloy steel e tsamaisana le thepa efe ea lapeng?
EN10216-2 P235GH e tšoana le GB/T5310 20G le 20MnG naheng ea heso (joalokaha ho bontšitsoe setšoantšong se ka holimo), le limaraka tse tšoanang tsa tšepe li kenyelletsa ASTM/ASME A-1, B; Tlhaloso: JIS STB410.
