Product Description
carbon steel Carbon steel
is an iron-carbon alloy with a carbon content of 0.0218%~2.11%. Also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.
classify；classification；assortment
according to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and easy cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two types;
according to the smelting method can be divided into flat furnace steel, converter steel;
According to the deoxygen method can be divided into boiling steel (F), calm steel (Z), semi-sedated steel (b) and special sedated steel (TZ);
According to the carbon content of carbon steel can be divided into low carbon steel (WC 0.25%), medium carbon steel (WC0.25% -0.6%) and high carbon steel (WC 0.6%);
According to the quality of steel, carbon steel can be divided into ordinary carbon steel (containing phosphorus, sulfur higher), high quality carbon steel (containing phosphorus, sulfur lower) and high grade quality steel (containing phosphorus, sulfur lower) and super grade quality steel.
species
carbon structural steel
number: Example Q235-AF, representing σ s=235MPa.
grade Note: Q is yield strength A quality grade (with ABCD level 4), F boiling steel.
features: low price, excellent process performance (such as weldability and cold formability). Application: General engineering structures and ordinary mechanical parts. Such as Q235 can make bolts, nuts, pins, hooks and less important mechanical parts and rebar in the building structure, section steel, steel bar, etc.
high quality carbon structural steel
number: Example 45,65 Mn, 08F.
brand note: directly represents the carbon content of the metal.
application: the manufacture of important mechanical parts of non-alloy steel, generally used after heat treatment.
Common steel number and use:
8F, low carbon mass fraction, good plasticity, low strength, used for stamping parts such as cars and instrument shell;
20, good plasticity and weldability, for the strength requirements are not high parts and carburizing parts, such as hood, welding container, small shaft, nuts, gasket and carburizing gear;
carbon steel
45,40 Mn, after adjusting the comprehensive mechanical properties are good, used for large force of mechanical parts, such as gear, connecting rod, machine tool spindle, etc.;
,65 Mn steel has high strength; used for the manufacture of various springs, locomotive rim, low speed wheels. carbon tool steel
grade number: for example, T12 steel means Wc = 1.2% carbon tool steel.
Note: T plus carbon content of metal.
characteristics: co-analysis steel and over-analysis steel, high strength, hardness, good wear resistance suitable for the manufacture of various low speed cutting tools. Common steel number and use:
T7, T8: make parts that bear a certain impact and require toughness. Such as sledgehammer, punch, chisel, woodworking tools, scissors.
T9, T10, T11: Make tools with high hardness and high wear resistance. Such as silk cone, small drill bit, punching die, hand saw blade.
T12, T13: Production is not impacted
