1. Carbon structural steel

Example q235-A ·F, σ S ≥235MPa note: Q is yield strength A quality grade (ABCD 4), F Boiling steel features: low price, excellent process properties (such as weldability and cold formability). Applications: General engineering structures and general machinery parts. Such as Q235 can make bolts, nuts, pins, hooks and less important mechanical parts and building structures in the rebar, steel, steel bar, etc

2. High quality carbon structural steel

Application: Non-alloy steels used in the manufacture of important mechanical parts are generally used after heat treatment. Common steel number and use: 08F, low carbon mass fraction, good plasticity, low strength, used for stamping parts such as automobile and instrument shell; 20, good plasticity and weldability, used for strength requirements are not high parts and carburizing parts, such as machine cover, welding container, small shaft, nut, washer and carburizing gear; 45,40 Mn, 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 for manufacturing various springs, locomotive rim, low speed wheels.

3. Carbon tool steel

Grade: for example, T12 steel represents a carbon tool steel with Wc=1.2%. T plus metal carbon content of thousands of features: eutectoid steel and eutectoid steel, high strength, hardness, wear resistance is suitable for manufacturing a variety of low speed cutting tools. Commonly used steel numbers and uses: T7, T8: the production of a certain impact and require toughness parts. Such as sledgehammer, punch, chisel, woodworking tools, scissors T9, T10, T11: manufacturing small impact requirements of high hardness and high wear resistance tools. Such as tap, small drill, die, hand saw blade T12, T13: make tools that are not impacted. Such as file, scraper, razor, measuring tool

4. Cast steel

For example, zg200-400 indicates the cast steel whose σs is greater than or equal to 200MPa and σb is greater than or equal to 400 mpa. Properties: casting properties are worse than cast iron, but mechanical properties are better than cast iron; Application: it is mainly used to manufacture important mechanical parts with complex shape, high mechanical property requirement, and difficult to be formed by forging and pressing in process, such as automobile gearbox shell, couplings and so on.
