304 Stainless Steel Casting | 304L Stainless Steel Casting
Stainless Steel 304 and Stainless Steel 304L is the common stainless steel grade used in the stainless steel investment casting process. They have the perfect corrosion resistance and have a high ease ability of fabrication, outstanding form-ability.
304 Stainless Steel
3304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3. It is also known as 18/8 stainless steel. With high-temperature resistance of 800 °C, it has good processing performance and high toughness. It is widely used in the industrial and furniture decoration industry and food medical industry. Stainless steel 304 is adapted in casting mainly for its strong corrosion resistance and strength. If take 304 stainless steel casting as a product, it will also have more advantages than 304 Stainless Steel.
Among the common marking methods on the market are 06 Cr19 Ni10 and SUS304. In which of 06Cr19Ni10 generally represents the national standard production. 304 generally represents the ASTM standard production. SUS 304 represents the Japanese standard.
304 stainless steel is a grade of stainless steel produced according to American ASTM standards. The most common form of 304 stainless steel is 18-8 stainless steel or 18/8 stainless steel. It contains 18 percent chromium and 8 percent nickel.
304L Stainless Steel
304L stainless steel is a low-carbon content version of 304 stainless steel. Its carbon content maximum is 0.03. This grade has slightly lower mechanical properties than the standard 304 grade. 304L stainless steel castings are softer. But the corrosion is better than 304 stainless steel castings.
Alloys steel of 304L is the most versatile and widely used alloy in stainless steel casting. It is ideal for home and commercial applications. It has excellent corrosion resistance and has a high ease of fabrication, outstanding formability.

304 stainless steel,304L stainless steel advantages for casting
304 (L) stainless steel has great advantages for casting.
- 1—The tensile strength is better than ordinary stainless steel materials. It can achieves the effect of 520MPA, so it is very convenient to process and easy to design.
- 2–The hardness, density, and specific heat capacity of 304 (L) stainless steel are very good. Both in processing and in use, they have very good stability and safety.
- 3–The biggest feature of 304 (L) stainless steel is that it contains more ni elements and cr elements inside. This greatly improves the corrosion resistance of 304 stainless steel. Such as the chemical, textile, and petroleum industries.
- 4–Oxidation Resistance: The maximum temperature to which type 304 can be exposed continuously without appreciable scaling is about 899℃.
- 5–Easy to weld with excellent weldability.
304 stainless steel casting in our foundry has a price advantage and good anti-rust properties. 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. Thus it is ideal for manufacturing food processors, household appliances, lockset, kitchen and sanitary ware, door and window, medical apparatus, architectural ornament, etc. The 304 stainless steel casting after polishing has a brilliant appearance and decorative effect.
