SAE 4130 domestic qib 30CrMo yog ib qhoalloy seamless steel yeeb nkabmuaj chromium thiab molybdenum.Nws lub zog tensile feem ntau yog siab dua 750MPa.Cov uas pom nyob rau hauv kev ua lag luam feem ntau yog tuav thiab tuab daim hlau.Nyias-walledSAE 4130 txias kos seamless steel kav
yog siv los ua cov tsheb kauj vab.IA thiab Tuam Tshoj Automobile Federation cov kev cai ntawm steel yeeb nkab cov ntaub ntawv rau kev sib tw yob tawb:precision mechanical seamless steel raj.
SAE 4130 alloy steel yeeb nkab muaj carbon 0.26 ~ 0.34, silicon 0.17 ~ 0.37, manganese 0.40 ~ 0.70, molybdenum 0.15 ~ 0.25, chromium 0.80 ~ 1.10.SAE 4130 yog sib npaug rau Japanese SCM430.Cov hlau no muaj zog thiab tawv, siab hardenability, thiab qhov tseem ceeb hardenable txoj kab uas hla ntawm cov roj yog 15-70mm;Lub zog kub ntawm cov hlau kuj yog qhov zoo, nrog rau qhov kub siab txaus lub zog hauv qab 500 ° C, tab sis ntawm 550 ° C Qhov tseem ceeb txo qis hauv kev siv.
Shandong Haihui Steel Kev Lag Luam Co., Ltd. muaj cov khoom muag txhua xyoo ntawm 20000 tons ntawm seamless steel kav, suav nrog ASTM A106 GR.B/A53GR.B/API 5L GR.B seamless steel kav, 15CrMo alloy seamless steel kav,20Cr alloy seamless steel kav, 40Cr alloy seamless steel kav, 27SiMn seamless steel kav, SAE1010/1020/1035/1045 seamless steel kav
