What is the role of S460QL chemical composition composition

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 S460QL chemical composition 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.

A572 grade can be divided into five levels: S460QL chemical composition, A572 grade 42 (290), 50 (345), 55 (380) for riveted, bolted or welded structural parts; A572 grade 60 (415) and 65 (450) for bridge riveted and bolted structural parts or welded structural parts for other purposes. Chemical composition of A572 Gr50 steel: C: ≤ 0.20, Si: ≤ 0.40, Mn: ≤ 1.50, P: ≤ 0.04, S: ≤ 0.05, Nb: ≤ 0.005-0.05.

According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 S460QL chemical composition is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export S460QL chemical composition situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.
