ASTM A302/A302M
A302 po'lat plitasi - ASTM A302 / A302M tomonidan ko'rsatilgan, payvandlangan qozonlar va bosimli idishlar uchun mo'ljallangan qotishma po'latdir. Bu marganets-molibden yoki marganets-molibden-nikel po'latdir, to'rtta navda (A, B, C va D) mavjud bo'lib, har xil kuch darajalariga ega. U odatda neft, gaz va energiya ishlab chiqarish sanoatida issiqlik almashtirgichlar, saqlash tanklari va reaktorlar kabi uskunalar uchun ishlatiladi.
