Product Description
Fixed length oil painting hydraulic cylinder astm 1020 cold drawn steel pipe
Yantai Xinpeng Steel Pipe Co., Ltd,established in Dec 1992, with
registered capital of 5 million Yuan, we have more than 20 years
experience in manufacturing and exporting steel pipe. Our company is equipped with JLB250T hydraulic cold drawn
machine set,LD120 precision cold rolled machine set,multple
precision straightening machine,box heat treat furnaces(8000-
10000mm).
Q235 ordinary carbon structural steel is also known as A3 steel.
Plain carbon structural steel-plywood is a kind of steel material.
Q stands for the yield limit of this material, and the subsequent 235 is
the yield value of this material, which is around 235MPa.With the
increase of the thickness of the material, the yield value is reduced.
Due to the moderate carbon content, the comprehensive performance
is better, and the strength, plasticity and welding performance are well matched, and the use is the most widely used.
Q stands for the yield limit of this material, and the subsequent 235 is
the yield value of this material, which is around 235MPa.As the
thickness of the material increases, the yield value will be reduced
(the thickness/diameter of the plate is less than 16mm and the yield
strength is 235MPa;16mm< plate thickness/diameter is less than 40mm,
yield strength is 225MPa;40mm< plate thickness/diameter is less than
60mm, yield strength is 215MPa;60mm< plate thickness/diameter =
100mm, yield strength is 205MPa;100mm< plate thickness/diameter is
less than 150mm, yield strength is 195MPa;150mm< plate thickness/
diameter is less than 200mm, yield strength is 185MPa.Due to the
moderate carbon content, the comprehensive performance is better,
the strength, plasticity and welding properties are well matched, and the
most widely used.
It is composed of Q+ number + quality level symbol + deoxidation
method symbol.Its steel number is called "Q", which represents the
yield point of the steel. The following figure represents the yield
point value, and the unit is MPa such as Q235, indicating the yield
stress (s) is 235 MPa carbon structural steel.
A symbol indicating the quality level and deoxidization method can
be indicated after the steel number.The quality level symbols are A,
B, C and D.Deoxidization method symbol: F denotes the effervescent
steel;B means semi - calm steel: Z means composed steel;TZ says
special sedative steel, composed steel is not a symbol, namely Z and
TZ are not standard.For example, Q235-AF represents A - grade boiling
steel.Specially used carbon steel, such as bridge steel, Marine steel,
etc., basically adopts the method of carbon structural steel, but in the
end of the steel number, the letter of use is added.
Our company mainly produces various specifications of cold drawn,rolled
precision steel tube,hydraulic cylinder tube and SRB(skived rolled burnished)
Tube, which are widely used in such industries as hydro-cylinder, automobile,
engineering machinery, textile machinery, printing machinery, oil drilling, etc.
Our company is also the distributor of several domestic well-known steel tube
plants in Shandong, and mainly distributes seamless steel tubes of all kinds of
materials.
