PREGUNTAS FRECUENTES

What is the difference between stainless steel 304 tube and 316 tube?

Stainless steel 304 and 316 are both austenitic grades, but 316 contains additional molybdenum, which enhances its corrosion resistance, particularly in marine environments. For most applications, stainless steel 304 tube is sufficient, but for environments with high chloride exposure, 316 is preferred.

Can stainless steel 304 tube be used in high-temperature applications?

Yes, stainless steel 304 tube can withstand temperatures up to 870°C (1600°F) without losing its strength or corrosion resistance, making it suitable for various high-temperature applications.

How do I maintain stainless steel 304 pipe?

Maintaining stainless steel 304 pipe involves regular cleaning with mild soap and water to remove dirt and contaminants. For more stubborn stains, a stainless steel cleaner can be used. Avoid using harsh chemicals or abrasive materials that could damage the surface.

Is stainless steel 304 pipe magnetic?

Stainless steel 304 pipe is generally non-magnetic due to its austenitic structure. However, slight magnetism may develop after cold working or welding, but this does not affect its performance.

Can stainless steel 304 pipe ¿se sueldan?

Yes, stainless steel 304 pipe can be easily welded using common welding techniques, such as TIG and MIG welding. It’s important to use the appropriate filler material and maintain proper welding conditions to avoid corrosion at the weld joints.
