ASTM A335 Alloy Steel Seamless Yeeb Nkab

ASTM A335 Alloy Steel Seamless Pipe Featured duab

Lus piav qhia luv luv:

ASTM A335 feem ntau hu ua chrome moly yeeb nkab vim cov tshuaj muaj Molybdenum (Mo) thiab Chromium (Cr).Molybdenum nce lub zog ntawm cov hlau thiab Chromium (los yog chrome) yog qhov tseem ceeb ntawm stainless hlau.Qhov sib xyaw ua ke ntawm chrome moly alloy steel yeeb nkab ua rau nws zoo tagnrho rau siv hauv cov chaw tsim hluav taws xob, cov chaw tsim khoom, cov chaw siv roj av, thiab cov kev pabcuam roj av uas cov kua dej thiab cov pa thauj mus los ntawm qhov kub thiab txias heev.

Kev xeem yuav tsum tau

Transverse / longitudinal: nro thiab flattening, hardness, khoov kuaj- rau cov khoom uas tau raug tshav kub-kho nyob rau hauv batch furnaces, cov kev ntsuam xyuas no yuav tsum tau ua nyob rau hauv 5% ntawm cov kav dej los ntawm txhua lub tshav kub ntau.Rau cov me me, ib lub yeeb nkab ntawm qhov tsawg kawg nkaus yuav tsum tau sim.

ASTM A335 Gr.P91 yuav tsum muaj hardness ntawm 250 HB / 265 HV (25 HRC).

Hydro testing: yuav tsum tau siv rau txhua qhov ntev ntawm cov yeeb nkab.

Qhov ntsuas hluav taws xob tsis muaj kev puas tsuaj yog xaiv tau.
