ALLOY STEEL
Creating the World's High-Performance Alloys.
Baosteel-alloy is the world leader in the invention, production and supply of high-nickel alloys for critical engineering.
Alloy | Description |
301 | High work-hardening rate due to reduced chromium and nickel content. |
302 | General purpose material with greater corrosion resistance but less work hardening than Type 301. This is the basic alloy of the austenitic group often referred to as 18:8. |
303 | Phosphorus and sulfur added for easier machining. For heavier cuts in automatic machining operations. |
304 | Carbon lower to minimize carbide precipitation. Less heat sensitive than other 18:8 steels. Used in high-temperature applications. |
304L | Extra low carbon content to avoid harmful carbide precipitation in welding applications. Corrosion resistance comparable to Type 304. |
316 | Contains molybdenum for better corrosion resistance—particularly to pitting. |
316L | Carbon lower than Type 316 to avoid carbide precipitation in welding applications. |
321 | Titanium added to avoid chromium-carbide precipitation when heated. Good for welding. |
410 | Basic martensitic type. General purpose, heat-treatable type used wher ecorrosion is not severe. |
410 HT | Heat treated version of Type 410. Basic martensitic type. General purpose, used where corrosion is not severe. |
416 | Free machining variation of Type 410 by virtue of added sulfur. |
420 | Hardenable stainless steel, which can be hardened to approximately Rockwell C 50. |
430F | Free machining version of Type 430. Non-hardenable by thermal treatment and is used for heat resistance and corrosion resistance under many conditions. Excellent machinability and good forming. |
440C | A high carbon type. Can be heat treated for high strength and hardness. Greater abrasion and wear resistance for use in bearing and bushing applications. Corrosion resistant only in the hardened condition. |
15-5 | High strength, corrosion resistant and easy to heat treat. Use for high pressure applications. |
17-4 | Chromium, nickel, copper, columbium, tantalum, and carbon balanced for high corrosion resistance and hardening by heat treatment. |
