S690QL1 specification stock with good price

S690QL1 specification, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with S690QL1 specification ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

According to the latest statistics of alacero, the consumption of finished steel S690QL1 specification products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.

In March, the daily output of key iron and steel enterprises fell on a month on month basis, while the overall inventory of S690QL1 specification and so on steel materials was lower but still at a high level. In terms of production, in March, according to the key statistics, the cumulative average daily output of pig iron, crude steel and steel for iron and steel enterprises was 1.824 million tons, 1.695 million tons and 1.766 million tons respectively, down 2.1%, 3.1% and 1.7% on a month on month basis.
