Lub ntsiab lus ntawm soldering hlau alloy

An iron alloy mainly composed of chromium and iron. It is one of the main alloying agents used in the steel industry. In addition to the main components chromium and iron, it also contains impurities such as carbon, silicon, sulfur, and phosphorus. Chromium iron contains 55% to 75% chromium, and is divided into high carbon (4% to 10% C), medium carbon (0.5% to 4% C), low carbon (>{{0}}.15 feem pua ​​​​rau 0.5 feem pua ​​C), thiab micro carbon (tsawg dua lossis sib npaug li 0.15 feem pua ​​C) chromium hlau raws li nws cov ntsiab lus carbon. High carbon ferrochrome, tseem hu ua carbon ferrochrome, thiab nruab nrab, qis, thiab micro carbon ferrochrome, kuj hu ua refined ferrochrome. Ib hom siab carbon ferrochromium uas ua los ntawm chrome ore nrog tsawg piv ntawm chromium rau hlau. Cov ferrochromium uas muaj 50 feem pua ​​~ 55 feem pua ​​Cr yog hu ua cub tawg nqi qib ferrochromium, thiab ferrochromium muaj nitrogen uas muaj N2 feem pua ​​~ 10 feem pua ​​yog siv raws li nitrogen alloying neeg sawv cev, kuj hu ua nitrided ferrochromium.
