-Classification:
Stainless steel rods can be divided into three types according to production technology: hot rolling, forging and cold drawing. Hot-rolled and forged stainless steel rods with dimensions (diameter, side length, thickness or distance between opposite sides) not greater than 250mm.
The specifications of hot-rolled stainless steel round bars are 5.5-250 mm. Among them: small stainless steel round bars of 5.5-25 mm are mostly supplied in straight strips and are commonly used as steel bars, bolts and various mechanical parts; stainless steel round bars larger than 25 mm are mainly used to manufacture mechanical parts or seamless steel pipe blanks.
Excellent pitting corrosion resistance and excellent high temperature creep strength.
-Features 1) The cold-rolled product has good gloss and beautiful appearance; 2) Added Mo, excellent corrosion resistance, especially pitting corrosion resistance; 3) Excellent high temperature strength; 4) Excellent work hardening (weak magnetism after processing ) 5) Non-magnetic in solid solution state; 6) Compared with 304 stainless steel, the price is higher.
-Scope of application: pipes, heat exchangers, food industry, chemical industry, etc.

The density of 304 stainless steel is 7.93 g/cm3. Austenitic stainless steel generally uses this value. 304 chromium content (%) 18–20. 304 is equivalent to my country’s 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 stainless steel is a universal stainless steel material. The anti-rust performance is stronger than that of 200 series stainless steel materials. It is also relatively good in terms of high temperature resistance and can reach temperatures as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. For oxidizing acids, it was found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid below the boiling temperature with a concentration of ≤65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
