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.

304 (18Cr-8Ni) material:
As a widely used steel, it has good corrosion resistance, heat resistance, low strength and mechanical properties; good hot workability such as stamping and bending, and no heat treatment phenomenon (no heat treatment phenomenon) Gloss, uses: Household products (Class 1 and 2 sanitary ware, wardrobes, indoor wiring, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical equipment, building materials, chemistry, food industry, agriculture, ships part.
-Stainless Steel Rod Grade:
200 stainless steel series: 201, 202 (chromium, nickel, manganese-austenitic stainless steel)
300 stainless steel series: 301, 302, 302HQ, 303, 304, 304L, 304F, 304HC, 316, 316L, 316F, 316S, 316Ti, 310, 310S, 314, 314L, 317, 317L, 321 (chromium, nickel-austenitic body stainless steel)
400 stainless steel series: 410, 420, 420J2, 430, 430F, 431 (ferritic and martensitic stainless steel)
Note: L stands for low carbon. For example, 304L has lower carbon content than 304. H and S represent high temperature resistance. For example, 310S is more heat resistant than 310, and 304H is more heat resistant than 304.
Stainless steel rods are divided into round rods, hexagonal rods, square rods, flat rods, round rods and solid rods. The ones with glossy surfaces are more expensive than those with black leather surfaces. 303 is a unique material in rods. It is an easy-to-turn (cut) type material and is mainly used for automatic lathe cutting. In addition: 304F, 303CU, and 316F are also easy-to-cut materials. Specifications: Ф1mm～Ф280mm.
