The high silicon heat-resistance stainless steel of this joint chromium nickel-saving type adopts conventional smelting process casting, through forge hot and solution treatment, finally makes the high silicon heat-resistance stainless steel of joint chromium nickel-saving type.
The high silicon heat-resistance stainless steel of joint chromium nickel-saving type of the present invention alloy material adopts the conventional smelting process of tradition, before casting, rare earth intermediate alloy is dropped into; Master alloy is made up of iron and rare earth metal, selects Fe-Ce or Fe-Y master alloy; Both compositions are respectively: in Fe-Ce master alloy, the quality percentage composition of Ce is 23.5%; In Fe-Y master alloy, the quality percentage composition of Y is 15%; After comprehensive batching is founded, casting, through forge hot and solution treatment, finally makes the high silicon heat-resistance stainless steel of joint chromium nickel-saving type.Steel in this composition range is again through certain temperature solution treatment after forge hot, and the tensile strength of room temperature is at 600～900Mpa scope, yield strength σ
0.2in 220～400Mpa scope, tension set is in 40～70% scopes, and hot strength and high-temp plastic are all better than 310S.
Mechanism of the present invention is as follows: according to alloying principle, for chromium, reduce the chromium content in metal with silicon; Silicon forms fine and close silicon oxide layer at alloy surface, carries heavy alloyed antioxidant property.In the present invention simultaneously, in order to fall low nickel content, replace nickel to carry out stable austenite with nitrogen, keep the austenitic matrix of alloy.
The present invention compared with prior art has following beneficial effect:
The present invention for chromium, reduces raw materials cost with silicon, and silicon forms fine and close silicon oxide layer at alloy surface simultaneously, stops further oxidized and corrosion of alloy, carries heavy alloyed corrosion resistance nature.The present invention significantly reduces the interdependency to precious metal, saves chromium and nickel resources, thereby makes and should have contribution for national resources saving.The present invention saves the tensile strength of room temperature of the high silicon heat-resistance stainless steel of chromium nickel-saving type alloy material at 600～900Mpa scope, yield strength σ
0.2in 220～400Mpa scope, tension set is in 40～70% scopes, and hot strength and high-temp plastic are all better than 310S.
