Wear resistantcan be used for both the abrasive wear and corrosion of the occasion, the main alloy elements is a kind of chromium and nickel alloy steel.
There are three types of wear resistant: austenitic stainless steel, component is [% ( quality ) of]:C0.04, Mn, Si0.6, Cr16, 1.3, Ni10.4, Mo2.2, annealed hardness is HV148; martensitic stainless steel, as [% ( quality ) ]:C 0.15, Mn 1, Cr 16.4, Quenched and tempered hardness HV387; ferrite stainless steel, component is [% ( quality ) ]:C 0.06, Mn 0.7, Si 0.4, Cr 17.4, Ni 0.3, annealed hardness HV180.
Generally in the abrasive wear is dominant in the corrosive wear process, appropriate selection of martensite stainless steel in corrosion, dominant in the corrosive wear process, appropriate chooses austenitic. Ferritic stainless steel for corrosion resistance than martensite and inferior to the austenite of. But its price is lower than that of austenite. In order to save the development of Ni Cr, Fe Mn Al stainless steel, such as 30Mn-10Al-Si, 20Mn-7Al, 30Mn-7Al-Si and 20Mn-5AL etc..
used in the manufacture of erosion, cavitation abrasion and seawater corrosion resistant parts. This kind of stainless steel in the as-cast microstructure austenite matrix.
