hot rolled steel coil ss400
Hot Rolled Steel Coil SS400
SS400 is a marking method for Japanese steel materials.
Hot rolled steel SS400 is classified according to tensile strength.
400 means that the minimum value of σb is 400MPa.
Q235 hot rolled steel coil is equivalent to the A3 and C3 steel in the old standard GB700-79 grades, and is a grade used in Russia's TOCT. The Q in its steel number represents yield strength.
What is the difference between hot rolled steel ss400 and hot rolled steel Q235？
SS400 is basically equivalent to Q235 (equivalent to Q235A used).However, there are differences in the specific indicators.
1.Q235 of the C, Si, Mn, S, P and other elements of the content of the requirements,
but SS400 only requires S, P less than 0.050.
2.Q235 has a yield point greater than 235 MPa,
while SS400 has a yield point of 245 MPa.
3.SS400 (steel for general structure) means that the tensile strength is greater than 400MPa general structural steel.
Q235 means that the yield point is greater than 235MPa ordinary carbon structural steel.
4.The standard number of SS400 is JIS G3101. the standard number of Q235 is GB/T700.
Application
HRC SS400 has a wide range of applications, mainly including the following areas:
Steel Structure Buildings: In steel structure plants, warehouses, stadiums and other buildings, SS400 hot rolled coils are commonly used to make beams, columns and other structural parts to enhance the structural stability of the building.
Building decoration: Hot rolled steel coil SS400 is used to make building decoration parts such as railings, handrails, door and window frames.
Foundation engineering: In the construction of foundation engineering, carbon steel coil SS400 can be used to make ground bolts, embedded parts, etc., to provide firm foundation support for the building.
Mould Manufacturing: In mold manufacturing, SS400 hot rolled coil can be used to make the framework and support structure of the mold to ensure the strength and stability of the mold.
Shipbuilding: Hot rolled steel sheet in coil SS400 is used in the construction of hull structures, decks, bulkheads, and other parts of ships.
Power Tower: As one of the main materials for power towers, hot rolled metal steel coil SS400 is characterized by high strength, corrosion resistance and easy processing, which can ensure the stability and safety of power tower.
