Thành Phần Hóa Học của Inox dạng thanh theo tiêu chuẩn BS EN 10088-3

Giới thiệu về tiêu chuẩn BS EN 10088-3

BS EN 10088-3 là tiêu chuẩn vật liệu cho các sản phẩm bán thành phẩm bằng thép không gỉ, dạng thanh, cây hay dây và các bộ phận cho các mục đích chung. Nó dùng chung cho các dòng thuộc thép không gỉ như: Ferritic, martensitic, kết tủa cứng, austenitic và austenitic-ferritic (duplex).

Thành phần hóa học của tất cả các loại thép không gỉ (Inox) tiêu chuẩn đều được liệt kê trong bảng dưới.

Lưu ý: Dữ liệu được cung cấp không nhằm thay thế dữ liệu được hiển thị trong các tiêu chuẩn riêng mà luôn phải tham chiếu.
