ແນະນຳ
ແຖບສະແຕນເລດ 304L ແມ່ນສະແຕນເລດ 300 ຊຸດທີ່ເປັນຫນຶ່ງໃນແຖບໂລຫະທີ່ໃຊ້ຢ່າງກວ້າງຂວາງທີ່ສຸດເນື່ອງຈາກການຕໍ່ຕ້ານການກັດກ່ອນແລະການຜະລິດທີ່ສວຍງາມ.
ທັງສອງແຖບສະແຕນເລດ 304 ແລະ 304L ສາມາດຖືກນໍາໃຊ້ສໍາລັບຄໍາຮ້ອງສະຫມັກທີ່ຄ້າຍຄືກັນຫຼາຍແລະຄວາມແຕກຕ່າງແມ່ນເລັກນ້ອຍ, ແຕ່ພວກມັນກໍ່ມີຢູ່.
ແຖບສະແຕນເລດ 304L ມີປະລິມານຄາບອນຕ່ໍາກວ່າແຖບສະແຕນເລດ 304.
ຄໍາຮ້ອງສະຫມັກ
ແຖບສະແຕນເລດ 304L ຖືກນໍາໃຊ້ຢ່າງກວ້າງຂວາງໃນໂຄງສ້າງລົດຍົນ, ອຸດສາຫະກໍາເຄມີ, ອຸດສາຫະກໍາປຸງແຕ່ງອາຫານ, ອຸດສາຫະກໍາສະພາບແວດລ້ອມທາງທະເລ, ພາກຮຽນ spring, ຊິ້ນສ່ວນເຊື່ອມແລະອຸດສາຫະກໍາແລກປ່ຽນຄວາມຮ້ອນ.
ແຖບສະແຕນເລດ 304L ຍັງສາມາດຖືກນໍາໃຊ້ໃນອຸດສາຫະກໍາຫນັກ, ໂດຍສະເພາະໃນສະພາບແວດລ້ອມທີ່ມີ corrosion ສູງ.
