Clssification da aikace-aikacen bututun ƙarfe mara nauyi
1. Structural sumul karfe bututu (GBT 8162-2008), yafi amfani ga general tsarin da inji tsarin, da wakilin abu (sa): carbon karfe, 20,45 karfe;Alloy karfeQ 345,20 Cr, 40 Cr, 20 CrMo, 30-35 CrMo, 42 CrMo, da dai sauransu.
2. Bututun ƙarfe mara ƙarfi don canja wurin ruwa (GBT 8163-2008).An fi amfani dashi a aikin injiniya da manyan kayan aikin bututun ruwa.Yana wakiltar 20, Q 345 da sauran kayan (alama).
3. Sumul karfe bututu ga low matsa lamba da matsakaici matsa lamba boilers (GB 3087-2008), shi ne irin high quality-carbon tsarin karfe zafi birgima sanyi kõma sumul karfe bututu, amfani da samar da daban-daban low matsa lamba tukunyar jirgi, matsakaici matsa lamba tukunyar jirgi. , ruwan zafi bututu, locomotive tukunyar jirgi superheated tururi bututu, babban shaye bututu, kananan hayaki bututu, baka bulo bututu, wakilin abu ne No.10,20 karfe.
4. High matsa lamba tukunyar jirgi tare da sumul karfe bututu (GB5310-2008), amfani da su tsirar high quality-carbon karfe gami karfe da bakin karfe sumul karfe bututu dumama surface high matsa lamba da kuma sama matsa lamba, wakilin abu ga20 g, 12Cr1MoVG, 15 CrMoG, da dai sauransu.
5. Sumul karfe bututu (GB 6479-2000) ga high matsa lamba taki kayan aiki, dace da high quality carbon tsarin karfe da gami karfe sumul karfe bututu da aiki zafin jiki na -40 ℃ da kuma aiki matsa lamba na 10-30 mA, wakiltar 20, 16 Mn, 12 CrMo, 12Cr2Mo da sauran kayan.
6. Bututun ƙarfe mara ƙarfi don fasa man fetur (GB 9948-2006), galibi ana amfani da shi don tukunyar jirgi, masu musayar zafi da jigilar bututun mai, kayan wakilcinsa sune 20, 12 CrMo, 1Cr5Mo, 1Cr19Ni11Nb, da sauransu.
7. Bututun ƙarfe don hakowa na ƙasa (YB235-70).Wani nau'i ne na bututun ƙarfe da ake amfani da shi don hakowa mai mahimmanci a cikin Sashen Ilimin Geology, wanda za'a iya raba shi zuwa bututun rawar soja, zoben rawar soja, bututu mai mahimmanci, casing da bututun ajiya bisa ga amfani.
8. Bututun ƙarfe mara ƙarfi don hakowa mai mahimmanci (GB 3423-82).Bututun karfe ne maras sumul da ake amfani da shi wajen hakowa, kamar bututun dillali, bututun bututu da casing.
9. Bututun hako mai (YB 528-65).Ana amfani da shi don yin kauri ko kauri da bututun ƙarfe maras sumul a ƙarshen RIGS na hako mai.Akwai nau'ikan bututun ƙarfe guda biyu, waɗanda aka raba su zuwa ƙarfe na ƙarfe da waya mara ƙarfe, haɗin bututun waya, waldar butt ɗin bututu mara waya da haɗin haɗin kayan aiki.
Fata cewa ta hanyar abubuwan da ke sama, za mu iya samun ƙarin fahimtar bututun ƙarfe mara nauyi.
