S355JR po'lat va S355MC po'latlari ikki xil konstruktiv po'latdir. Ular quyidagi farqlarga ega:
Materiallardan foydalanish:
S355JR po'lati asosan ko'priklar, binolar va mexanik uskunalar kabi umumiy konstruktiv muhandislik va ishlab chiqarish sohalarida qo'llaniladi.
S355MC po'lati avtomobil sanoatida va sovuq shakllangan qismlarni ishlab chiqarishda keng qo'llaniladigan-sovuq shakllangan{2}}issiq{3}}prokatlangan po'latdir.
Kuch darajasi:
S355JR po'lati odatda 355MPa minimal rentabellikga ega va qalinligi 16 mm dan kam bo'lsa, uning kuchlanish kuchi 470-630MPa ni tashkil qiladi.
Taqqoslash uchun, S355MC po'lati yuqori rentabellikga ega, odatda 355-510MPa va kuchlanish kuchi 430-550MPa.
Tarkibi va qayta ishlash:
Ushbu ikki po'latning kimyoviy tarkibi biroz farq qiladi. S355JR po'latida uglerod, kremniy, marganets, oltingugurt va fosfor kabi elementlar mavjud bo'lsa, S355MC po'latida niobiy, vanadiy va titan kabi iz qotishma elementlari ham mavjud.
Bunga qo'shimcha ravishda, S355JR po'lati odatda issiq{1}}prokat yoki issiqlik bilan ishlov berilgan-formatda, S355MC po'lati esa issiq-o'ralgan holda yetkazib beriladi va yaxshi sovuq shakllanish xususiyatlariga ega.
Foydalanish shartlari:
S355MC po'lati yuqori quvvat va yaxshi sovuq shakllanish xususiyatlariga ega bo'lganligi sababli, u yuqori quvvat va murakkab shakllarni talab qiladigan qismlarni ishlab chiqarish uchun javob beradi.
S355JR po'lati umumiy konstruktiv muhandislik va mexanik uskunalar uchun ko'proq mos keladi.
Ilovalar:
S355JR: Asosan ko'priklar, binolar va boshqa og'ir qurilishlar kabi tizimli ilovalarda qo'llaniladi.
S355MC: Shassi va boshqa konstruktiv qismlar uchun avtomobil sanoati kabi yuqori quvvat va shakllanishni talab qiladigan ilovalar uchun ko'proq mos keladi.
Issiqlik bilan ishlov berish:
S355JR: Odatda issiqlik bilan ishlov berilmaydi-.
S355MC: Istalgan mexanik xususiyatlarga erishish uchun söndürme va temperleme kabi maxsus jarayonlardan o'tishi mumkin.

S355MC po'lat nima?
EN 10149-2 S355MC hisoblanadiyuqori{0}}kuchli past-qotishma po'latdan yasalgan rulonkonstruktiv qismlar va butlovchi qismlarni ishlab chiqarish uchun avtomobil sanoatida keng qo'llaniladi.
S355MC ning moddiy ekvivalenti nima?
S355MC nemis DIN QStE360TM, Yaponiya JIS SPFH540 va VDA ekvivalenti HR340LA kabi boshqa standartlarda ekvivalentlarga ega. Turli yetkazib beruvchilar, shuningdek, S355MC standartiga javob beradigan SSAB Domex 355MC kabi ikki-sertifikatlangan mahsulotlarni taklif qilishadi.
S355j2 va S355MC o'rtasidagi farq nima?
S355MC va S355J2 ikkalasi ham konstruktiv po'lat navlaridir, lekin ular ishlab chiqarish standartlari va mo'ljallangan ilovalarida farqlanadi. S355MC EN 10149-2 standarti boʻyicha termomexanik prokat boʻlib, sovuq shakllanish va avtomobilsozlik sanoati uchun maxsus moʻljallangan, S355J2 esa EN 10025-2 standartiga mos keladi va past haroratlarda (odatda -20 daraja) oʻtkazilgan zarba sinovlari bilan mukammal zarba chidamliligi bilan mashhur.
S355MC materialining rentabellik kuchi qanday?
355 MPa
Yupqa taneli{0}}mikrotuzilmasi va yuqori darajadagi tozaligi tufayli S355MC markasi yorilishsiz sovuq bukish, buklash va sovuq flaneslash uchun juda mos keladi. S355MC markasining nomi uning yuqori rentabellik kuchiga ishora qiladi. Bu355 MPa.
