Good 09CuPCrNi-A weathering steel performance from BBN

The effect of nitrogen (N) on the properties of 09CuPCrNi-A weathering steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in 09CuPCrNi-A weathering steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Q355GNH weathering steel: Q——The first letter of the Chinese pinyin of "Qu" in the yield strength;355——The lower limit of the lower yield strength of steel, in N/mm²;GNH——respectively the first letter of "Gao, Nai, Hou" Chinese Pinyin;Quality grades are divided into A, B, C, D, E(1)Q355GNH executive standard: GB/T 4171-2008(2)Q355GNH smelting method: the steel is smelted by converter or electric furnace, and it is killed steel.

The company sold 50,000 tons of hot rolled plates to Southeast Asian countries, which will help the construction of relevant 09CuPCrNi-A weathering steel key projects in countries along the “Belt and Road”. In response to the local environment and construction needs in Southeast Asia, the company has made a number of improvements to its export products, with excellent cost performance such as low emissions and low fuel consumption. It is an ideal compaction equipment for the 09CuPCrNi-A weathering steel construction of high-grade highways, railways, airports, ports and industrial sites. Loved by customers from countries along the “Belt and Road”.
