10 # Seamless simbi pombi
Tsanangudzo Pfupi
Production specification:
Kunze dhayamita yesimbi pombi 20-426
Simbi pombi rusvingo ukobvu 20-426
Kemikari yakagadzirwa:
● Kwete 10 isina musono simbi pombi kemikari:
Carbon C: 0.07~0.14″ silicon Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.35 chromium Cr: ≤0.15Nickel0 ≤0 Nickel 2: ≤0.
Mechanical property:
Michina yemhando , kuoma: kusina kupisa, ≤156HB, saizi yemuenzaniso: 25mm.
High quality carbon structural simbi:
No. 10 seamless simbi pombi haina zvimwe alloy elements (kunze kwezvakasara zvinhu) kunze kabhoni (C) element uye imwe uwandu nesilicon (Si) nokuda deoxidation (kazhinji kwete kupfuura 0.40%), manganese (Mn) (kazhinji kwete kupfuura 0.80%, kusvika 1.20%) alloy elements.
Simbi yakadaro inofanira kuva nezvose zvemakemikari uye mechanical properties.Zviri mukati mesarufa (S) uye phosphorus (P) zvinowanzodzorwa pasi pe0.035%.Kana ichidzorwa pasi pe0,030%, inonzi simbi yepamusoro, uye "A" inofanira kuwedzerwa mushure megiredhi, yakadai se20A;Kana P inodzorwa pazasi 0.025% uye S inodzorwa pazasi 0.020%, inonzi yakawedzera yepamusoro simbi, uye "E" inofanira kuwedzerwa mushure megiredhi kuratidza mutsauko.Kune zvimwe zvakasara zvealloying zvinhu zvakaunzwa musimbi neyakagadzirwa zvinhu, senge chromium (Cr), nickel (Ni), mhangura (Cu), nezvimwewo, zviri muCr≤0.25%, Ni≤0.30%, Cu≤0.25%.Mamwe mabhureki emanganese (Mn) anokwana kusvika 1.40%, anozivikanwa sesimbi yemanganese.
No. 10 isina musono simbi pombi uremu calculation formula :[(okunze dhayamita - madziro ukobvu)* rusvingo ukobvu]*0.02466=kg/ m (kurema pamamita)
