Zanglamaydigan po'lat yumaloq barlar uchta xalqaro standartlar bilan tartibga solinadi, ularning har biri noyob e'tiborga ega:
ASTM A276 (AQSh):Ostenitik (304, 316), temir (430) va shabliylar (410). U kimyoviy tarkibni (masalan, 18-20% 304 uchun), keskinlik kuchi (304 mk), sirtni tugatish (22 mkin uchun 32 mkinga teng yoki 32 mkinga teng yoki taxminan 32 mekini sovuq uchun) tugatdi.
10088-3 (EI):Raqamli kodlar (1.4301=304}, {}}}, 1.4401=316 bo'yicha baholaydi (1.4401=316) Stricter oltingugurt cheklovlari bilan (<0.015% for 1.4301) to enhance corrosion resistance. It mandates more rigorous testing for intergranular corrosion (e.g., ASTM A262 Practice E) for welded parts.
Jis g4303 (Yaponiya):Qattiq o'lchovli bardoshli bardali barlarni (dimeta uchun ± 0,01mm uchun) sovuqqa aylantiradi<10mm) for precision applications like watch components. It includes grades like SUS304 and SUS440C (high-carbon stainless for cutting tools).
Uchta standartni eritmadan tayyor mahsulot va korroziyani sinovdan o'tkazishni talab qiladi (masalan, 316 uchun 1000 soat davomida tuzni purkagich), tibbiy, dengiz va kimyoviy moddalarni qayta ishlash bo'yicha ishonchliligini ta'minlaydi.
