Q235A ipleyiti yentsimbi

I-boiler steel plate isetyenziswa kakhulu ekwenzeni iibhoyili ezahlukeneyo kunye nezixhobo ezibalulekileyo. Ekubeni i-boiler steel plate isebenza kwiqondo lokushisa eliphakathi (ngaphantsi kwe-350 ° C) kunye noxinzelelo oluphezulu, ngaphezu koxinzelelo oluphezulu, lukwaxhomekeke kwimpembelelo, umthwalo wokukhathala kunye nokunyuka komphunga wamanzi. Kuyafuneka ukuba kuqinisekiswe amandla athile, kwaye ine-welding elungileyo kunye nokusebenza okugoba okubandayo. Amabanga aqhelekileyo: Q245R, A5155 ibakala 55, A5156 ibanga 60, Q235A carbon steel plate, A5166 grade 65, A51670 grade.

Ukwandiswa kwentsimbi ephantsi-i-alloy ephezulu-amandla yi-15% -23%, kunye nefuthe lokufunxa amandla kwiqondo lokushisa elikhulu kune-34J. I-Q235A ipleyiti ye-carbon steel, i-alloy ephantsi yomelele intsimbi ineplastiki elungileyo kunye nokumelana nempembelelo, enokuthi ithintele i-brittle fracture ngexesha lempembelelo kwaye yenze ukugoba okubandayo kunye nokuwelda kube lula. Ukongezelela, ukushisa kwe-brittle transition ye-alloy ephantsi-amandla aphezulu ensimbi iphantsi, kwaye ixabiso le-absorption ye-E-grade steel kwi-40 ° C ayikho ngaphantsi kwe-27J. Oku kubaluleke kakhulu kumacandelo obunjineli kunye neendlela zokuthutha ezifana neenqwelo, iinqanawa, amaqonga e-oyile engaselunxwemeni, izitya, iibhulorho, njl.
