30CrMnSiA ishidi lensimbi eligoqiwe elishisayo

I-alloy structural steel iwuhlobo lwensimbi olusetshenziswa njengezingxenye zemishini nezinto ezihlukahlukene zobunjiniyela, eziqukethe i-alloy element eyodwa noma ngaphezulu.
I-30CrMnSiA ikhabhoni emaphakathi enamandla aphezulu nokusebenza kabi kokushisela.
I-30CrMnSiA inamandla aphezulu kanye nokuqina okwanele ngemva kokucisha kanye nokushisa, futhi ukuqina nakho kuhle. Ngemuva kokucisha nokushisa, izinto ezisetshenziswayo zingasetshenziswa njenge-shaft yesondo lokugaya, amagiya kanye nama-sprockets.
I-30CrMnSiA inokucutshungulwa okuhle, ukuguqulwa okuncane kokucubungula kanye nokumelana nokukhathala okuhle. Okwezingxenye zeshaft nepiston nokunye. Isetshenziswa ezingxenyeni ezihlukahlukene zokugqoka ezikhethekile njengezimoto nezindiza.
Impahla inombala omnyama futhi ifakwe uthayela ingangeza ubuhle nokugqwala.

UBUHLU BOKUNIKEZELWA KWE-GB/T 30CrMnSiA

Ukuqinisekisa ikhwalithi

Ukuhlolwa okungezansi kuzokwenziwa ekukhiqizeni.
(1) ukutholwa kwemisebe---RT;
(2) ukuhlolwa kwe-ultrasonic---UT;
(3) Ukuhlola Izinhlayiya Ezizibuthe-MT;
(4) ukuhlola ukungena-PT;
(5) ukutholwa kwephutha lamanje-ET
