904L Stainless steel medium thickness plate super austenitic stainless steel is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosion conditions. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking has high resistance, not easy to appear corrosion spots and cracks, pitting corrosion resistance is slightly better than other steel types, with good processability and weldability, can be used in pressure vessels.

444 Stainless steel medium thickness plate，444 (00Cr18Mo2) is an ultra-low carbon nitrogen, containing 18% chromium and 2% molybdenum, high corrosion resistance of ferritic stainless steel. The yield strength of 444 is equivalent to 1.5 times that of carbon steel and 6 times that of FRP. It has outstanding advantages in earthquake resistance, snow resistance, wind pressure resistance and impact resistance. SUS444 ferritic stainless steel has high thermal conductivity, about 130% ~ 150% of chromium-nickel austenitic stainless steel, which is very suitable for heat exchange purposes. The coefficient of thermal expansion is small, and the team is only 60% ~ 70% of the chromium-nickel Olympic stenitic stainless steel, which is very suitable for thermal expansion, cold contraction and thermal circulation. The steel has good plasticity and toughness, and is suitable for drawing, rolling and stamping. In particular, stress corrosion resistance is the most excellent, in high chloride medium corrosion resistance is better than ordinary ferrite stainless steel and austenitic stainless steel, generally do not produce chloride stress corrosion rupture. After the addition of Ti,Mo and other elements, the performance of resistance to pore corrosion and crevice corrosion is improved

439 Stainless steel medium thickness plate 439 steel is to reduce the content of C on the basis of ordinary ferrite material (430), while adding Ti and other stabilizing elements, so that the resistance to intergranular corrosion, formability and weldability of the steel are improved. Compared with 304 steel, although the elongation is lower (about 30%), but the strength, corrosion resistance is equivalent, and corrosion resistance is better than 200 series materials.
