How to protect S690QL elastic modulus from crack

ASME SA514 gr J alloy steel sheet element composition%C: 0.12-0.21, Si: 0.20-0.35, Mn: 0.45-0.70, P max.: 0.035, S max.: 0.035, Mo: 0.50-0.65, B: 0.001-0.005

Advantages of S690QL elastic modulus: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

Strip steel is mainly divided into hot-rolled ordinary strip steel, cold-rolled ordinary strip steel, hot-rolled high-quality strip steel and cold-rolled high-quality strip steel. The S690QL elastic modulus, hot-rolled carbon strip steel is made of ordinary carbon structural steel, and is hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. The hot-rolled carbon strip steel is mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products.

The European steel industry has been hit hard by the coronavirus pandemic. The auto industry, the second largest consumer of S690QL elastic modulus and so on steel, was temporarily shut down, while construction, the biggest consumer, slowed sharply in the UK in the last week of March, experts reported. It can be expected that the current crisis (which is still intensifying) will have the same or even greater impact on the steel industry as the global financial crisis.
