A672 C65 materiali nima?
A672 GrC65 CL22 belongs to the carbon-manganese-silicon steel series. Its chemical composition is meticulously designed, with carbon content controlled below 0.22%, manganese content between 1.0-1.5%, and appropriate silicon added to enhance strength and toughness. This alloy formulation enables the steel pipe to maintain good plasticity while possessing high yield strength (>415MPa) va kuchlanish kuchi (485MPa dan katta yoki unga teng).
Ayniqsa, diqqatga sazovor jihati shundaki, maxsus boshqariladigan prokat va sovutish jarayonlaridan o‘tgandan so‘ng, material sezilarli darajada donni tozalash effektiga ega bo‘lib, -46 darajada xizmat ko‘rsatish talablariga to‘liq javob berib, past{0}}temperaturaga mukammal darajada ta’sir qiladi. Korroziyaga chidamliligiga kelsak, mikro-qotishtiruvchi elementlar qo'shilishi va oltingugurt va fosfor tarkibini qat'iy nazorat qilish orqali uning HIC (Vodorod bilan bog'liq bo'lgan yorilish) va SSC (Sulfidli stressli korroziya yorilishi) ga chidamliligi NACE MR0175 standartlariga javob beradi, bu uni vodorod sulfidini o'z ichiga olgan og'ir ish sharoitlari uchun ayniqsa mos qiladi.
