Generally speaking, 1803 has a higher cost performance and stronger market competitiveness than 304 stainless steel, while reducing the material cost and improving the strength and hardness of the material.

Their element contents are different: 304 is 8 Ni 18 Cr 1803 is to adjust the content of elements such as Ni, and the content of Ni is not as high as 304.

1803 has better corrosion resistance than 304 stainless steel under various practical conditions after cold working, such as bending, stamping and hard forming. The yield strength is greater than 1.3 times of that of 304 stainless steel, and the elongation is not less than 45%. Wear resistance and fatigue performance are better than 304 stainless steel; The welding performance is good, the strength after welding is higher than that of 304 stainless steel, and the corrosion resistance is equivalent to that of 304 stainless steel.
