201-2 (S20100) stainless steel plate gas processing, and alloying

201-2 (S20100) stainless steel plate of inert gas processing: blow Ar to 201-2 (S20100) the liquid steel, while the gas itself does not participate in the metallurgical reaction. All the small bubbles in 201-2 (S20100) the growing every the liquid steel is equivalent to a "small vacuum chamber" (H2, N2, CO in the bubble point pressure is close to zero), which have "gas" washing effect.

As for method of refining outside the furnace to produce 201-2 (S20100) stainless steel, it is applied under different CO partial pressure of carbon chromium, and the balance relation between the temperature. Since the inert gas and oxygen refine decarburization, it can reduce the carbon and oxygen reaction of CO partial pressure. In that condition of low temperature and carbon content reduce, chromium oxide won’t be oxidized.

Early alloying process for 201-2 (S20100) stainless steel :We add one or several of alloying elements to201-2 (S20100) liquid steel , so that to meet product specifications of the operation. This process isreferred to alloying. In most cases deoxidizing and alloying was conducted at the same time. We add 201-2 (S20100) steel deoxidizer in part of the consumption of steel deoxidized, discharge into products; The left parts isabsorbed by molten steel in 201-2 (S20100) , and they will make alloying effect. The process before Corporation in deoxidization action complete, and alloy to join 201-2 (S20100) steel absorption effect, is known as alloying.
