METALL QOTISHMALARINING MARKALANISHI TAHLILI
Ataxonova Sayyora Qoraboyevna
Andijon mashinasozlik instituti "Materialshumslik va yangi materiallar texnologiyasi kafedrasi" katta o'qituvchisi ataxonova.sayyora@mail .ru Mo'ydinova Dilafruz Raimjonovich Toshkent davlat texnika universiteti 2-bosqich talabasi
Ushbu maqolada O'zbekistonda va chet elda zanglamas po'latlarnig markalanish tahlili, po'latlarning ishlab chiqarilishiga ko'ra, kimyoviy tarkibiga ko'ra, ishlatilish sohasiga ko'ra turlari, issiq va sovuqqa chidamli zanglamaydigan po 'latdan yasalgan rulon tasmalar keng yoritilgan.
Kalit so'zlar: kompozitsion, import, yevronormalar, issiqbardosh, korroziyabardosh, qotishma, prujina, ressor, sharikli podshipnik po 'latlari, legirlasah, GOST, AQSH standartidagi analoglar
В данной статье анализируются марки нержавеющих сталей в Узбекистане и за рубежом, виды сталей по производству, составу, типу применения, горячему и холодному рулону нержавеющей стали.
Ключевые слова: композиционные, импортные, европейские стандарты, жаростойкие, коррозионностойкие, сплавы, рессорные, рессорные, шарикоподшипниковые стали, сплавы, ГОСТ, аналоги стандарта США.
This article analyzes stainless steel grades in Uzbekistan and abroad, types of steels by production, composition, type of application, hot and cold stainless steel coil.

rejalar, yuqori fizikaviy mexanik va foydalanish xossalariga ega bo'lgan ma'lum polimer va kompozitsion materiallarni fizikaviy kimyoviy uslublardan ishlab chiqarish yoki mavjud ishlab chiqarish uslublarini takomillashtirishni belgilab beradi.
MUHOKAMA VA NATIJALAR
O'zbekistonda biz metall va qotishmalarni markalanishini rus alfavitidan foydalanamiz. Oliy-talim talabalarimiz ishlab chiqarish korxonalariga amaliyot o'tash uchun borganlarida Xorijdan kelgan birlamchi rulon sortament listlarni raqamlar bilan tamg'alanganliklarini ko'radilar. Bu metall listlarni kimyoviy tarkibi va mexanik, fizik, kimyoviy va texnologik xususiyatlari qay darajada ekanliklari haqida ma'lumot topolmaydilar. Mashinasozlik Institutida, ayniqsa mutaxasislik fanlaridan metall va uning qotishmalarini Evropa va Evroosiyoda qanday markalanishi haqida nafaqat materialshunoslik yo'nalishi, balkim mashinasozlikning barcha yo'nalish talabalariga keng ma'lumotlar berishimiz kerak.

XULOSA
Xulosa qilib aytganimizda Oliy-talim talabalarimiz ishlab chiqarish korxonalariga amaliyot o'tash uchun borganlarida, Xorijdan kelgan birlamchi rulon sortament listlarni raqamlar bilan tamg'alanganliklarini ko'radilar. Bu metall listlarni kimyoviy tarkibi va mexanik, fizik, kimyoviy va texnologik xususiyatlari qay darajada ekanliklari haqida ma'lumot topolmaydilar. Mashinasozlik Institutida, ayniqsa mutaxasislik fanlaridan metall va uning qotishmalarini Evropa va Evroosiyoda qanday markalanishi bo'yicha mashinasozlikning barcha yo'nalish talabalariga, ilmiy izlanuvchilariga yuqorida keltirilgan jadval asosidagi ma'lumotlarni bilishi juda ham zarurdir.
