304 stainless steel material has strong corrosion
resistance in nitric acid below the boiling temperature of ≤
65%. It also has good corrosion resistance to alkaline
solutions and most organic and inorganic acids. A high alloy
steel alloy steel that resists corrosion in air or chemically
corrosive media.
304 stainless steel pipe can be used in general chemical
equipment, atomic energy industrial equipment.
The anti-rust performance of 304 stainless steel is stronger
than that of 200 series stainless steel. High temperature
resistance is also good, can be as high as 1000-1200 degrees.
304 stainless steel has excellent stainless corrosion
resistance and good resistance to intergranular
corrosion.
304L is ultra-low carbon stainless steel with carbon
content reduced to less than 0.03% to avoid intergranular
corrosion
H in 304H refers to high temperature, high carbon content is
the guarantee of high temperature strength. GB150 requires
austenitic steel to be used at 525 degrees or more, the
carbon content is not less than 0.04%, and carbide is
strengthening phase, especially high temperature strength.
Better than pure austenite.
