CHÚ THÍCH: Các loại thép được cho trong bảng này có thể so sánh với các loại thép được cho trong Bảng 1. Tuy nhiên, để so sánh các loại tương tự nhau, cần kiểm tra mỗi nguyên tố trước khi thay thế

^a Xem các nguồn trong Thư mục tài liệu tham khảo

^b Thép của Hoa Kỳ (Mỹ) được đưa ra trong ASTM A 959 và trong UNS; nếu số hiệu của thép được cho trong ngoặc thì thép chỉ có một số hiệu UNS.

^c Thép của Châu Âu được đưa ra trong EN 10088-1:2005 và trong "Stahl-Eisen-Liste", nếu số hiệu của thép được cho trong ngoặc thì thép chỉ được đưa ra trong "Stahl-Eisen-Liste".

^d Tiêu chuẩn công nghiệp Nhật Bản.

^e Thép Trung Quốc có số hiệu ISC được đưa ra trong GB/T20878.

^f I = thép đồng nhất với loại thép ISO; N = loại (mác) thép có thành phần thích hợp hơn nhưng không đồng nhất, W = hoàn toàn thích hợp.
