SS 309S / SS 309H Wire

SS 309S Stainless simbi isimbi yakasanganiswa kwazvo austenitic Stainless simbi inoshandiswa kune yayo yakasarudzika oxidation yekudzivirira, yakakwirira-tembiricha, simba, uye inokambaira kuramba. Iyo yakadzika nickel yemukati yeStainless Steel 309, ichienzaniswa neStainless Steel 310, inowedzera kuramba kwayo kurwiswa kwehydrogen sulfide (H2S) pakupisa kwakanyanya. Iyo yakaoma uye ductile uye inogona kuve nyore kugadzirwa uye kugadzirwa. SS 309S ndiyo yakaderera-kabhoni vhezheni, uye inokurudzirwa, inoshandisa uko kunzwisiswa uye kunotevera ngura nepamusoro tembiricha condensates panguva yekuvhara kunogona kuunza dambudziko. Stainless Simbi 309S inoshandiswa kune yayo yepamusoro-tembiricha oxidation kuramba uye kuramba kurwiswa kweH2S. 309S Stainless Simbi inogona kuumbwa, kudhindwa uye kudhonzwa zviri nyore. In-process annealing inowanzodiwa kuwedzera ductility uye kuderedza kuoma.
