Steels Classification
(47 votes)Welding Equipment
Based on chemical composition, steels are classified into 3 major groups :
Carbon Steels
Alloying elements do not exceed these limits: 1% carbon, 0.6% copper, 1.65% manganese, 0.4% phosphorus, 0.6% silicon, and 0.05% sulfur.
Alloy Steels
Steels that exceed the element limits for carbon steels. Also includes steels that contain elements not found in carbon steels such as nickel, chromium (up to 3.99%), cobalt, etc.
Stainless Steels
Contains at least 10% chromium, with or without other elements. Based on the structures, stainless steels can be grouped into three grades:
| Austenitic: | Typically contains 18% chromium and 8% nickel and is widely known as 18-8. Nonmagnetic in annealed condition, this grade can only be hardened by cold working. |
| Ferritic: | Contains very little nickel and either 17% chromium or 12% chromium with other elements such as aluminum or titanium. Always magnetic, this grade can be hardened only by cold working. |
| Martensitic: | Typically contains 12% chromium and no nickel. This grade is magnetic and can be hardened by heat treatment. |
Classification of Steels. The Society of Automotive Engineers (SAE) has established Triple Alloy steels which include Nickel (Ni), Chromium (Cr), and Molybdenum (Mo)
