Ilovalar: A588 konstruktiv po'lat plitasi odatda me'moriy xususiyatlar, ko'priklar, uzatish minoralari, yuk vagonlari va korroziyaga chidamlilikni talab qiluvchi boshqa tizimli ilovalarda qo'llaniladi.
Farqlar
Korroziyaga qarshilik:
A572 super qalin po'lat plitalar A588 ning atmosfera korroziyaga chidamliligini ta'minlaydigan qo'shimcha elementlar tufayli A588 HSLA issiq{2}}prokatli po'lat bilan bir xil darajada korroziyaga chidamliligiga ega emas.
Foydalanish maqsadi:
A572 asosan yuqori quvvat talab qiladigan konstruktiv ilovalar uchun ishlatiladi, A588 esa atmosfera korroziyasiga duchor bo'lgan tashqi tuzilmalar uchun maxsus mo'ljallangan.
Ob-havo xususiyatlari:
A588 atrof-muhitga ta'sir qilganda vaqt o'tishi bilan himoya patina hosil qiladi va uning atmosfera korroziyasiga chidamliligini oshiradi.
A572 va A588 o'rtasida tanlov o'tkazayotganda, qo'llash uchun eng mos materialni aniqlash uchun loyihaning joylashuvi, atmosfera sharoitlariga ta'sir qilish, kerakli mexanik xususiyatlar va korroziyaga chidamlilik zarurati kabi omillarni hisobga oling.
