Tsawg Alloy Steel Yeeb Nkab
Cov hlau tsis tshua muaj hlau yog feem ntau siv rau hauv kev tsim kho thiab kev tsim vaj tsev, xws li hauv kev tsim cov choj, lub tsev thav duab, kis tau tus yees, thiab lwm yam.
Tsawg alloy seamless steel yeeb nkab yog hais txog alloy hlau nrog tag nrho cov ntsiab lus alloying ntawm tsawg dua 5%. Tsawg alloy steel yog txheeb ze rau carbon steel. Nws yog tsim los ntawm carbon steel kav. Txhawm rau txhim kho kev ua haujlwm ntawm cov hlau, ib lossis ob peb lub ntsiab lus alloying yog txhob txwm ntxiv rau cov hlau. Thaum cov alloy ntxiv ntau tshaj li cov ntsiab lus ntawm cov hlau uas ua los ntawm cov txheej txheem ntau lawm, cov hlau hu ua alloy steel.
Thaum tag nrho cov ntsiab lus alloy tsawg dua 5%, nws yog hu ua low alloy steel yeeb nkab. Ordinary alloy steel yeeb nkab feem ntau tsawg dua 3.5%. Thaum cov ntsiab lus alloy nyob nruab nrab ntawm 5-10%, nws yog hu ua nruab nrab alloy steel yeeb nkab. Thaum cov ntsiab lus alloy ntau dua 10%, nws yog hu ua high alloy steel yeeb nkab.
Qhov taw tes tawm ntawm cov qauv hlau txiav txim siab qhov kev ntxhov siab uas cov qauv tuaj yeem tiv taus yam tsis muaj deformation mus tas li. Qhov tsawg kawg nkaus qhov taw tes ntawm cov pa roj carbon zoo steel yeeb nkab yog 235MPa. Qhov tsawg kawg nkaus cov ntsiab lus ntawm ib qho qis-alloy high-strength steel yeeb nkab yog 345MPa. Yog li ntawd, raws li kev sib raug zoo ntawm nws cov ntsiab lus, qhov kev cia siab ntawm cov yeeb nkab uas tsis tshua muaj zog hlau yog 1.4 npaug siab dua li cov kav hlau carbon steel.
Alloy tube khoom:20G (ST45. 10CrMo910, A335P22, T22, STFA24.
Alloy yeeb nkab siv cov qauv:GB5310-1995, GB17396-1998, DIN17175-79, GB6479-2000, GB9948-2006, thiab lwm yam.

Alloy Steel Yeeb Nkab
Tsawg alloy seamless steel kav yog siv dav hauv cov hauv qab no:
1. Petrochemical kev lag luam: siv los tsim cov kav dej, ntim thiab reactors hauv cov khoom siv petrochemical.
2. Hluav taws xob: siv rau hauv kev tsim cov kav dej, flues thiab boilers hauv cov khoom siv hluav taws xob.
3. Kev tsim kho hauv nroog: siv los tsim cov kab teeb, kab thiab phab ntsa hauv kev tsim vaj tsev.
