It is alloyed with 18%-28% Cr and 3%-10% Ni in the condition of low C. Comparing with ferritic stainless, duplex stainless steel has higher plasticity, ductility and better intergranular corrosion resistance and weldability.
ມັນແມ່ນ alloyed ກັບ 18% -28% Cr ແລະ 3% -10% ຕ່ໍາຢູ່ໃນສະພາບຕ່ໍາ C. ປຽບທຽບກັບສະແຕນເລດ, ເຫລັກສະແຕນເລດເຟີໄລ duplex ມີສະຕິກທີ່ສູງຂຶ້ນ, ຄວາມຫນຽວແລະຕ້ານ corrosion intergranular ທີ່ດີກວ່າແລະ weldability.
