304 stainless steel is the most common grade of stainless steel castings, largely due to its excellent corrosion resistance and value. It contains between 16 and 24 percent chromium and up to 35 percent nickel, as well as small amounts of carbon and manganese.
The most common form of 304 stainless steel is 18-8 stainless steel or 18/8 stainless steel, which contains 18 percent chromium and 8 percent nickel.
304 stainless steel has great advantages for casting: it is susceptible to corrosion from chloride solutions, or from saline environments like the coast. Chloride ions can create localized areas of corrosion, called “pitting,” which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.
304 stainless steel casting in CFS foundry has the price advantage and good anti-rust property due to its material. The 304 is a steel number for wrought steel, Cast 304 is equivalent to CF-8 of the US, or 1.4308 of Germany. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for manufacturing of food processor, household appliances, lockset, kitchen and sanitary ware, door and window, medical apparatus, architectural ornament, etc. For your information, the 304 stainless steel casting after polishing has a brilliant appearance and decorative effect.
