ASTM A790 S32205 Hlau Yeeb Nkab

ASTM A790 S32205 Duplex Steel Yeeb Nkab yog ib qho ferritic-austenitic stainless hlau yeeb nkab uas feem ntau siv rau hauv cov ntawv thov kev lag luam vim nws lub zog zoo heev thiab kev tiv thaiv corrosion. Nws yog tsim los ntawm kev sib xyaw ua ke ntawm chromium, molybdenum, thiab npib tsib xee, uas ua rau nws zoo tshaj rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg.

Cov txheej txheem ntawm kev tsim ASTM A790 S32205 Duplex Steel Pipe muaj ob theem tseem ceeb: melting thiab fabrication. Cov hlau yog melted nyob rau hauv lub cub hluav taws xob, thiab ces muab pov rau hauv ntau yam duab xws li billets los yog ingots. Cov kauj ruam tom ntej no suav nrog forging, dov, lossis kos cov hlau rau hauv qhov xav tau thiab loj. Cov txheej txheem no yog ua raws li kev kho cua sov, uas ua kom cov yeeb nkab steel muaj qhov zoo tshaj plaws lub zog thiab corrosion kuj.
