FAQ
Q1: Is 304 stainless steel pipe magnetic?
A1: 304 is generally non-magnetic, but slight magnetism may appear after cold working or welding.
Q2: What's the difference between 304 and 304L?
A2: 304L contains lower carbon (<0.03%), offering better weldability and resistance to intergranular corrosion.
Q3: Can 304 stainless steel pipe be used for high-temperature applications?
A3: Yes, 304 stainless steel can withstand temperatures up to 870°C (1600°F) under intermittent service.
Q4: How do I choose between seamless and welded 304 pipes?
A4: Seamless pipes are ideal for pressure or high-temperature applications; welded pipes are more economical for structural or low-pressure use.
