A small amount of Nb is sufficient to obtain excellent comprehensive properties of P355GH boiler steel specifiction etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
16MnDR steel plate is a kind of low temperature pressure vessel steel plate. The quality control level of p355gh boiler steel specifiction and 16MnDR steel plate: the purity of molten steel is high, the impurity content is very low. 16MnDR steel plate chemical composition is in accordance with the executive standard GB 3531. The packaging, mark and quality certificate of 16MnDR steel plate shall comply with the relevant provisions of GB247.
BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, p355gh boiler steel specifiction plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.
The purpose of p355gh boiler steel specifiction quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of p355gh boiler steel specifiction. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
