EN steel grade S275JR plates for low pressure service

ArcelorMittal USA said EN steel grade S275JR plates it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). EN steel grade S275JR plates, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.
