We have a fully advanced and modernized warehouse that stores tonnes of our value-adding a573 grade 65 [450] high strength carbon steel products, which we source out from the mills that are compliant with the universal guidelines for plate production.

The steel grades a573 grade 65 [450] high strength carbon steel of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of a573 grade 65 [450] high strength carbon steel steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate a573 grade 65 [450] high strength carbon steelhas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

Composition characteristics of low alloy structural steel, a573 grade 65 [450] high strength carbon steel: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

The chemical composition difference between a573 grade 65 [450] high strength carbon steel, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between a573 grade 65 [450] high strength carbon steel, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than a573 grade 65 [450] high strength carbon steel 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
