DIN125A.This is one of our main product.
According to the quality of carbon percentage is divided into:
1. Low-carbon steel (C: ≤0.25%), also known as mild steel, mild
steel is easy to accept a variety of processing such as forging,
welding and cutting, commonly used in the manufacture of chains,
rivets, bolts, shafts and so on.
2. Medium carbon steel (C: 0.25% <C ≤ 0.6%) have a variety of
products, such as killed steel, semi-killed steel, boiling steel.
In addition to carbon can also contain a small amount of manganese
(0.70% ~ 1.20%). According to the quality of products divided into
ordinary carbon structural steel and high-quality carbon structural
steel. Hot processing and cutting performance is good, poor welding
performance. Strength, hardness than low carbon steel, plasticity
and toughness than low carbon steel. Without heat treatment, direct
use of hot-rolled material, cold drawn material, can also be used
after heat treatment. Quenched and tempered carbon steel has a good
comprehensive mechanical properties. The maximum hardness that can
be achieved is about HB538 and the tensile strength σb is 600 to
1100 MPa. As a result, medium carbon steels are used most widely
for a variety of applications at moderate levels of strength,
except for construction materials, which are also used extensively
in the manufacture of various mechanical parts.
3. High-carbon steel (C:> 0.6%), often referred to as tool
steels, has a carbon content of greater than 0.60% to 1.70% and can
be hardened and tempered. Hammers, crowbars, etc. made of steel
with a carbon content of 0.75%; cutting tools such as drill bits,
wire tapping, reamers and the like are made of steel having a
carbon content of 0.90% to 1.00%.
