The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of S550 stainless steel brake lines, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

In these countries, the impact of the epidemic in South Korea is relatively serious, and in other countries, the current epidemic control is more appropriate. However, it is understood recently that the epidemic control in South Korea has begun to show a positive trend, and the impact of the epidemic will gradually slow down in the future. Therefore, as far as the direct export of S550 stainless steel brake lines and so on steel is concerned, the overall impact is relatively limited.

The S550 stainless steel brake lines processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S550 stainless steel brake lines steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
