QN1803 Stainless Steel Coil
Description
QN1803 stainless steel corrosion resistance has been professiona tested by SGS.Compared with traditional stainless steel, its pitting corrosion equivalent (PREN=Cr+3.3Mo+30N-Mn) is above 19.0.The uniform corrosion resistance under the environment of dilute sulfuric acid, acetic acid + salt is far better than that of traditional stainless steel,and the yield strength is more than 1.3 times that of raditional stainless steel, and it has an elongation of not less than 45%.lt adopts the proportioning method of "high-nitrogen saving nickel” plus copper intake, which increases the use of nitrogen while reducing the intake of expensive nickel, effectively reducing costs, and the addition of copper makesits sterilization performance better.Excellent,it is a perfect substitute for traditional stainless steel.
Under the premise of ensuring the original quality, QN1803 stainless steel is committed to researching and developing low-cost, high-strength stainless steel products to promote the development of the stainless steel industry.
The application fields are as follows: decorative pipes, industrial pipes, refrigerators, livestock breeding equipment,diamond nets, 5G communication equipment, food machinery, precision springs, home appliances, high-strength fasteners, building curtain walls, building roofs and load-bearing structures, except for the above Application areas include: power distribution cabinets, bus kiosks, sanitation equipment, drainage system manhole covers, floor drains, etc.
