What is astm a573 structural steel grade 70 properties use

Types of steel plates our company supply: A36 carbon structural steel plate, A572 low-alloy high-strength steel plate, astm a573 structural steel grade 70 properties, steel plate for bridge, S355 steel plate for building structure, Grade AH36 steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, mould steel plate, steel plate for alloy structure, API 5L Gr.B pipeline steel plate, high-strength high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the astm a573 structural steel grade 70 properties, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the astm a573 structural steel grade 70 properties rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of astm a573 structural steel grade 70 properties steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
