Cold rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum
With the rapid development of the transportation industry, the role of the tank is becoming increasingly important. Increasingly demanding environment for tank has higher requirements for materials, especially 2001 oil drum used for cold-rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) requirements of its material have been strictly regulated. This article will make an in-depth introduction the meeting the requirements of YB / T055-1994 cold-rolled thin steel plate and hot-dip galvanized thin steel plate.
The cold rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum need to meet the requirements of YB / T055-1994 standard. The chemical composition of cold-rolled thin steel plate and hot-dip galvanized thin steel plate should meet the requirements of GB/T701 medium carbon steel and GB/T1591 low alloy structural steel with stringent chemical requirements, whose carbon content should be less than 0.20%. Hot-dip galvanized thin steel plate further requires the steel surface with an appropriate amount of phosphoric acid zinc-dipping.
In terms of mechanical properties, the cold-rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum should meet the requirements of GB/T702 cold-rolled steel sheet tensile test, GB/T1591 low alloy high strength structural steel, and GB/T16270 steel plate for bridge. The yield strength of the cold-rolled thin steel plate should not be less than 270 MPa and the tensile strength should meet the requirements of YB/T055-1994 for the corresponding surface grades. For hot-dip galvanized thin steel plate, the requirements of YB / T055-1994 must be met.
In terms of the surface quality of cold-rolled steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum, it should meet the requirements of YB / T055-1994. No dislocation, deformation, cracks, folding, leakage and other flaws should allow on the surface of cold-rolled thin steel plate. The surface should be planed, ruffled and no residual grinding grains should allow.The quality requirements of cold-rolled thin steel plate should meet the requirements of surface grade YB/T654-1994. The hot dip galvanized thin steel plate must be non-porous, without exposed zinc, local zinc-rich, exposed rust and peeling layers on the surface.
The relevant performance indicators of cold rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum should meet the requirements of YB / T055-1994. The cold-rolled thin steel plate should pass the thickness and width detection and the dipping thickness of hot-dip galvanized thin steel plate should meet the requirements of YB/T655-1991. The appearance quality grade should be no less than 1. The smooth surface should allow no obvious scratches, and should meet the requirements of surface quality grade YB/T654-1994.
The above is a brief introduction to the cold rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum, which fully embodies the quality requirements of YB / T055-1994. In summary, in terms of material composition, the chemical composition of the steel must meet the requirements of the standard, the mechanical properties must meet the requirements of the corresponding surface grades, and the surface quality requirements must also be strictly complied with. Only in this way can we ensure that the cold rolled thin steel plate and hot-dip galvanized thin steel plate (YB / T055-1994) for 2001 oil drum meet the requirements of YB / T055-1994 and ensure users safety.
