Hom 904L Phaj

Hom 904L phaj kuj muaj kev tiv thaiv zoo rau ntau lwm cov inorganic acids, xws li phosphoric acid thiab feem ntau cov organic acids. Txawm li cas los xij, cov kua qaub thiab cov kua qaub uas muaj halide ions tuaj yeem ua rau muaj kev txhoj puab heev, thiab corrosion kuj ntawm 317L, 317LMN thiab 904L yuav tsis txaus.

Hom 904L phaj yog lub siab alloy austenitic stainless hlau uas paub txog nws cov khoom corrosion. Qhov no qis carbon version ntawm Hom 904L phaj kuj muaj lwm yam txiaj ntsig rau cov neeg siv xws li:

• Tsis-magnetic

• Cov khoom muaj zog corrosion dua li Hom 316L thiab 317L

• Zoo tsis kam mus rau sulfuric, phosphoric thiab acetic acids

• Siab tiv taus crevice thiab kev nyuaj siab corrosion cracking

• Zoo heev formability thiab weldability
