304 stainless steel has different designations in various countries and standard systems. Here are the corresponding grades in major countries or regions:

1. China (GB Standard):
   • 0Cr18Ni9
   • S30408 (corresponds to 304 in the ASTM standard)
2. USA (ASTM/AISI Standard):
   • 304
   • UNS S30400 (UNS designation)
3. Europe (EN Standard):
   • 1.4301 (EN 10088 standard)
   • X5CrNi18-10 (chemical composition designation)
4. Japan (JIS Standard):
   • SUS304
5. Russia (GOST Standard):
   • 08Х18Н10 (08X18H10)
6. UK (BS Standard):
   • 304S15

• Material Properties: 304 stainless steel is known for its excellent corrosion resistance, toughness, and weldability. It’s commonly used in industries like food processing, chemical equipment, medical devices, and construction due to its durability and ability to withstand harsh environments.
• Machinability: Although 304 stainless steel is machinable, it tends to harden during machining, leading to tool wear and heat buildup. Using sharp and wear-resistant cutting tools, such as carbide tools, is essential to maintain precision and tool life.
• Cutting Parameters: Due to its high strength and work hardening characteristics, lower cutting speeds and moderate feed rates are recommended to prevent overheating and tool wear. Consistent monitoring of cutting conditions is important to achieve a balance between efficiency and part quality.
• Cooling and Lubrication: Adequate cooling and lubrication are crucial when machining 304 stainless steel. Using high-quality coolants reduces heat generation, minimizes tool wear, and ensures a better surface finish. Common coolants include emulsion or synthetic fluids.
• Tolerance Control: Tight tolerances can be achieved in machining 304 stainless steel, with typical tolerances ranging from ±0.02mm to ±0.1mm, depending on the part’s application and design specifications.
• Surface Finish: The natural corrosion resistance of 304 stainless steel often eliminates the need for additional surface treatment. However, to improve the surface finish or further enhance corrosion resistance, techniques like electro-polishing or passivation may be applied.
• Welding and Assembly: If the part requires welding or assembly, 304 stainless steel is well-suited to various welding methods such as TIG and MIG welding, without losing its corrosion-resistant properties.
