Ordinary carbon structural steel grades, performance characteristics and uses, high-quality carbon structural steel grades, performance characteristics and uses, carbon tool steel grades, performance characteristics and uses

The main grades of ordinary carbon structural steel include Q195, Q215, Q235, Q255 and Q275. The performance characteristics and uses of these grades are different, as follows:

‌Q195‌: Low carbon content, low strength, but good plasticity, toughness and processing performance. Mainly used for rolling thin plates and wire rods, used for roof panels, decorative panels, general dust removal pipes, packaging containers, instrument shells, switch boxes, protective covers, etc. ‌Q215‌: The strength is slightly higher than Q195, and the uses are similar. It is also used for welding steel pipes, galvanized welded pipes, furnace supports, anchor screws, bolts, round nails and other hardware parts ‌Q235‌: Moderate carbon content, good comprehensive performance, strength, plasticity and welding performance are well matched. It has the widest range of uses and is used in buildings and engineering structures, such as steel bars, bridges, vehicles, boilers, containers, ships, etc. ‌ Q255‌: The performance is similar to Q235, with slightly higher strength but lower plasticity. Mainly used for riveting and inspection structures ‌ Q275‌: High strength and hardness, good wear resistance. Used to manufacture shafts, agricultural machinery, wear-resistant parts, rail joint splints, etc. ‌ Performance characteristics ‌ The performance characteristics of ordinary carbon structural steel mainly include: ‌ Strength‌: The strength of different grades is different, and the yield limit of Q235 is about 235MPa ‌ Plasticity‌: It has good plasticity and is suitable for cold forming and welding. ‌ Toughness‌: It has certain toughness and is suitable for bearing certain impact loads. ‌ Weldability‌: It has good welding performance and is suitable for welding structural parts. ‌ Price‌: It is relatively cheap and suitable for large-scale use. ‌ Uses
