Features: low price, excellent process performance (such as weldability and cold formability).
Application: general engineering structures and general mechanical parts. For example, Q235 can be used to make bolts, nuts, pins, hooks and less important mechanical parts, as well as rebar, section steel and steel bars in building structures.
2. High quality carbon structural steel
Application: Non-alloy steels for manufacturing important mechanical parts are generally used after heat treatment.
Commonly used steel grades and uses:
08F, low mass fraction of carbon, good plasticity, low strength, used for stamping parts such as automobile and instrument housing;
20. Good plasticity and weldability, used for parts with low strength requirements and carburized parts, such as machine covers, welding containers, small shafts, nuts, washers and carburized gears, etc.;
45, 40Mn, good comprehensive mechanical properties after quenching and tempering, used for mechanical parts with large force, such as gears, connecting rods, machine tool spindles, etc.;
60, 65Mn steel has high strength; used in the manufacture of various springs, locomotive rims, and low-speed wheels.
Features: It belongs to eutectoid steel and hypereutectoid steel, with high strength and hardness and good wear resistance, suitable for manufacturing various low-speed cutting tools.
Commonly used steel grades and uses:
T7, T8: Make parts that withstand a certain impact and require toughness. Such as sledgehammer, punch, chisel, carpentry tools, scissors.
T9, T10, T11: Manufacturing tools that require high hardness and high wear resistance with less impact. Such as taps, small drills, dies, hand saw blades.
T12, T13: Make tools that are not impacted. Such as files, scrapers, razors, measuring tools.
4. Cast steel
Performance: Casting performance is worse than cast iron, but mechanical properties are better than cast iron.
Application: It is mainly used to manufacture important mechanical parts with complex shapes and high mechanical performance requirements, but it is difficult to form by forging and other methods in technology, such as gearbox housings for automobiles, couplers and couplings for rolling stock, etc.
