Abstract

The invention discloses high-strength and anti-corrosion composite pattern steel and further discloses a manufacturing method of the high-strength and anti-corrosion composite pattern steel correspondingly. The high-strength and anti-corrosion composite pattern steel comprises a base plate and a pattern composited layer with a single face or double faces being composited to the base plate in a rolled mode. The base plate comprises the chemical elements of, by mass, 0.01-0.20% of C, 0.10-0.5% of Si, 0.5-2.0% of Mn, 0.02-0.04% of Al, 0.005-0.018% of Ti, 0.005-0.020% of Nb, B, 0.006% or the lessof N and the balance Fe and inevitable impurities, wherein B is larger than 0 and smaller than or equal to 0.0003%. According to a high-strength and anti-corrosion composite steel plate, the strengthis high, corrosion resistance is high, the yield strength is larger than or equal to 470 MPa, the tensile strength is larger than or equal to 610 MPa, the shearing strength is larger than or equal to410 MPa, and the elongation percentage is larger than or equal to 40%.

Description

technical field

[0001] The invention relates to a composite plate and a manufacturing method thereof, in particular to a composite patterned steel and a manufacturing method thereof. Background technique

[0002] The checkered plate has the advantages of beautiful appearance and non-slip surface, so it is widely used in the market. At present, pattern steel is divided into carbon steel pattern plate and stainless steel pattern plate. However, the above-mentioned patterned steel has the following problems respectively:

[0003] For the carbon steel checkered plate, during its long-term use, there are potential safety hazards in the use process due to the corrosion of carbon steel. Therefore, in order to prevent corrosion, it is necessary to carry out anti-corrosion treatment on the checkered steel regularly. The anti-corrosion treatment process consumes a lot of production costs and labor costs. It not only has extremely high requirements for the regional environment (for e...
