QN series stainless steel sheet is a new stainless steel material developed by China Tsingtuo Group, which replaces nickel with nitrogen to reduce costs, improve the strength and hardness of stainless steel, while improving its corrosion resistance, stabilising γ and suppressing δ-Fe. Thus it can substantially improve the performance of stainless steel. The quality level of QN series stainless steel sheet is much higher than the quality level of general steel in the market, for example QN1803 has a typical composition that meets the European standard EN 10088-2:2014 (grade 1.4376).
