Question: What is the difference between stainless steel 304, 304L, 304H?
Answer: Type 304 refers to those materials widely used in the manufacture of wire mesh, these materials contain 18% chromium or 8% nickel (18-8) on the basis of stainless alloys, and this material will not produce Rust will not oxidize even if the temperature rises to 1400 degrees Fahrenheit. The 304L model is similar in nature to the 304 model, the difference between the two is that the 304L material has better weaving and welding characteristics due to its low carbon content.
304H features: stainless heat-resistant steel, with good pipe bending and welding process performance, corrosion resistance, high lasting strength and structural stability, and very good cold deformation ability. The operating temperature is up to 650°C, and the anti-oxidation temperature is up to 850°C.
