“Otitọ, Innovation, Rigorousness, ati Imudara” le jẹ ero inu ti ile-iṣẹ wa si igba pipẹ lati ṣe agbejade papọ pẹlu awọn alabara fun isọdọtun-ifowosowopo ati èrè ifowosowopo fun ojutu pipe. A ni bayi ọja nla ti Cr Mo alloy steel pipe lati mu awọn ipe alabara wa fun ati awọn iwulo. Pẹlu ikẹkọ daradara, imotuntun ati oṣiṣẹ ti o ni agbara, a ti ni iduro fun gbogbo awọn eroja ti ipese ojutu paipu. Nipa orisun didara ti o ga pupọ ati iṣẹ akude, a nlọ si ibi-afẹde ti lati jẹ ọkan ninu olupese ojutu pipe nla julọ ni agbaye. A tẹtisi ifarabalẹ si esi lati ọdọ awọn alabara wa ati pese awọn idahun lẹsẹkẹsẹ. Iwọ yoo ni rilara lẹsẹkẹsẹ wa ti oye ati iṣẹ akiyesi.
Nipa ohun-ini Cr Mo pipe, ọpọlọpọ awọn eroja irin wa ni ipa lori rẹ. Ibasepo laarin ohun-ini ẹrọ ti paipu ati eroja irin akọkọ bi isalẹ:
Erogba (C): Akoonu erogba ninu irin pọ si, aaye ikore, agbara fifẹ ati alekun lile, ṣugbọn ṣiṣu ati awọn ohun-ini ipa dinku. Nigbati akoonu erogba ba kọja 0.23%, iṣẹ alurinmorin ti irin bajẹ, nitorinaa ti o ba lo fun alurinmorin Akoonu erogba ti irin igbekalẹ alloy-kekere ni gbogbogbo ko kọja 0.20%. Akoonu erogba ti o ga julọ yoo tun dinku resistance ipata oju aye ti irin, ati irin-erogba irin giga ni agbala iṣura ṣiṣi jẹ rọrun lati ipata; ni afikun, erogba le mu awọn tutu brittleness ati ti ogbo ifamọ ti irin.
Ohun alumọni (Si): Ohun alumọni ti wa ni afikun bi a atehinwa oluranlowo ati deoxidizer ninu awọn steelmaking ilana, ki awọn pa irin ni 0.15-0.30% silikoni. Ohun alumọni le ṣe ilọsiwaju idiwọn rirọ, aaye ikore ati agbara fifẹ ti irin, nitorinaa o jẹ lilo pupọ bi irin rirọ. Ilọsoke ninu iye ohun alumọni yoo dinku iṣẹ alurinmorin ti irin.
Manganese (Mn). Ninu ilana ṣiṣe irin, manganese jẹ deoxidizer ti o dara ati desulfurizer. Ni gbogbogbo, irin ni 0.30-0.50% manganese. Manganese le mu agbara ati lile ti irin pọ si, mu lile ti irin pọ si, mu iṣẹ ṣiṣe gbona ti irin, ati dinku iṣẹ alurinmorin ti irin.
Phosphorus (P): Ni gbogbogbo, irawọ owurọ jẹ nkan ti o ni ipalara ninu irin, eyiti o mu ki irẹwẹsi tutu ti irin pọ si, dinku iṣẹ alurinmorin, dinku ṣiṣu, ati dinku iṣẹ titẹ tutu. Nitorinaa, akoonu irawọ owurọ ti o wa ninu irin ni gbogbogbo nilo lati jẹ kere ju 0.045%, ati pe ibeere fun irin didara ga jẹ kekere.
Sulfur (S): Sulfur tun jẹ ẹya ipalara labẹ awọn ipo deede. Ṣe irin gbona brittle, din irin ductility ati toughness, ati ki o fa dojuijako nigba forging ati sẹsẹ. Sulfur tun jẹ ipalara si iṣẹ ṣiṣe alurinmorin, idinku idena ipata. Nitorinaa, akoonu sulfur ni gbogbogbo nilo lati jẹ kere ju 0.045%, ati pe ibeere fun irin didara ga jẹ kekere. Ṣafikun 0.08-0.20% sulfur si irin le mu ẹrọ pọ si, ati pe gbogbo rẹ ni a pe ni irin gige ọfẹ.
Vanadium (V): Ṣafikun vanadium si irin le ṣatunṣe awọn irugbin eto ati mu agbara ati lile pọ si.
Niobium (Nb): Niobium le ṣatunṣe awọn irugbin ati ilọsiwaju iṣẹ alurinmorin.
Ejò (Cu): Ejò le mu agbara ati toughness dara si. Awọn daradara ni wipe o jẹ prone si gbona brittleness nigba gbona ṣiṣẹ, ati awọn Ejò akoonu ni alokuirin, irin jẹ igba ti o ga.
Aluminiomu (Al): Aluminiomu jẹ deoxidizer ti o wọpọ ni irin. Iwọn kekere ti aluminiomu ti wa ni afikun si irin lati ṣatunṣe awọn oka ati ki o mu ilọsiwaju ti o lagbara.
