● QN1803 stainless steel
Q stands for high-strength steel, N stands for nitrogen alloying, 18 stands for 18% Cr, and 03 stands for 3% Ni.
Compared with the 304ss,QN1803 has the following advantages:
1) The pitting equivalent (PREN=Cr+3.3Mo+30N-Mn) is above 19.0, and it has at least the same pitting corrosion resistance as 304 stainless steel. The uniform corrosion resistance under the environment of dilute hydrochloric acid, dilute sulfuric acid, acetic acid + salt is far better than that of 304 stainless steel.
2) The corrosion resistance is better than that of 304 stainless steel under various cold working conditions such as bending, stamping and hard forming.
3) The yield strength is more than 1.3 times that of 304 stainless steel, and it has an elongation of not less than 45%. Wear resistance and fatigue performance are better than 304 stainless steel.
4) Good welding performance, the strength after welding is higher than that of 304 stainless steel, and the corrosion resistance is equivalent to that of 304 stainless steel.
In general: QN1803 improves the strength and hardness of the material on the basis of ensuring the corrosion resistance equivalent to that of 304 stainless steel, while reducing the material cost. It has a higher cost performance and stronger market competitiveness than 304 stainless steel.
In the future, it may completely replace 304 in some areas.
On the one hand, as a high-quality, high-performance, low-cost stainless steel product, QN1803 not only satisfies the market demand, but also enhances the overall competitiveness of Chinese stainless steel products and industry!
On the other hand, phase out non-standard 200 series with extremely poor corrosion resistance ratio and poor corrosion resistance and unhealthy galvanized products. Under the applicable corrosive environment of 202, D11, and 430, fields with higher requirements for strength will be fully replaced. Steel type.
In addition, in the corrosive environment where 304 is applicable, fields with higher requirements for strength will completely replace 304 steel and become the mainstream stainless steel product in the future.
● QN1701
The new product QN1701 is a new material in the Tsingshan high nitrogen, high strength, nickel-saving austenitic stainless steel series products that are relatively economical and costeffective.QN1701 not only has better corrosion resistance than American standard 202 and 430 stainless steel, but also improves material strength and hardness, and reduces production costs. Make it have a higher cost performance and stronger market competitiveness than 202,430 stainless steel.
☆ Excellent corrosion resistance: PREN is greater than 15.0. It has better pitting corrosion resistance than 202 stainless steel. No rusting in 5% sodium chloride neutral salt fog atmosphere for 500 h；
☆ High strength: the yield strength is more than 1.40 times that of 430 (Q235 grade) stainless steel, and it exceeds the carbon steel Q355 grade.
☆ Easy to shape: elongation is greater than 50%, LDR is equivalent to 202;
☆ Excellent welding performance: the strength and corrosion resistance of the product after welding are better than 202
● Packaging
