Matauriro: Non-standard Stainless simbi pombi inogona customized maererano mutengi zvinodiwa
253MA (UNS S30815) isimbi isingadziviriri austenitic stainless simbi yakagadzirirwa maapplication ayo anoda simba rekukwenya rakakwirira uye kunaka kwekusagadzikana.Iyo tembiricha yekushanda kwayo ndeye 850 ~ 1100 °C.
Kemikari ye253MA yakaenzana, izvo zvinoita kuti simbi ive yakanyatsokodzera mashandiro akazara mutembiricha ye850 ° C-1100 ° C, yakanyanya kukwirisa oxidation resistance, oxidation tembiricha inosvika 1150 ° C, uye yakanyanya kukwirira kukambaira.Kugona uye zvinokambaira kuputika simba;kupikisa kwakanyanya kune yakanyanya tembiricha corrosion uye brashi corrosion kuramba mune yakawanda gaseous media;kusimba kwegoho repamusoro uye kusimba kwesimba pakupisa kwakanyanya;yakanaka formability uye weldability, uye zvakakwana machinability.
Pamusoro peiyo alloying element chromium uye nickel, iyo 253MA Stainless simbi zvakare ine shoma shoma yepasi isingawanzo simbi, nekudaro ichivandudza zvakanyanya antioxidant kugona kwayo.Nitrogen inowedzerwa kuvandudza zvinhu zvinokambaira uye kuita iyi simbi izere austenite.Kunyangwe zviri mukati mechromium uye nickel zvakadzikira, simbi dzisina simbi dzakadaro dzine muzviitiko zvakawanda zvakafanana tembiricha yemhando sesimbi dzakasanganiswa alloy uye nickel base alloys.
