It can still maintain good oxidation resistance at high temperatures and is suitable for boilers and heat exchangers.
How to forge 304 stainless steel coil?
1. Raw material preparation: Select high-quality stainless steel billets to ensure that the chemical composition meets the standards.
2. Hot rolling or cold rolling: The billets are processed into coils through hot rolling or cold rolling processes.
3. Annealing treatment: The coils are heated to 1010°C-1120°C and then quickly cooled to eliminate internal stress and improve corrosion resistance.
3. Stainless steel surface treatment: Bright annealing, wire drawing, sandblasting or polishing are performed according to customer needs.
4. Stainless steel quality inspection: Each batch of 304 stainless steel products undergoes chemical composition analysis, mechanical property testing and surface quality inspection to ensure zero defects in the products.

FAQ
304 stainless steel is not magnetic.
304 stainless steel is also called SUS304. It is a metastable stainless steel. After annealing, it is in a single austenite structure state, and austenite structure is non-magnetic, so 304 stainless steel is non-magnetic.
304 stainless steel is an austenitic stainless steel. Although it is non-magnetic, it can also produce weak magnetism in rare cases.
304 stainless steel coil is a commonly used stainless steel material, and its thickness standard is regulated by national and industry standards.
National standards stipulate that the thickness range of hot-rolled coils is between 3.0mm and 100mm, and the thickness range of cold-rolled coils is between 0.3mm and 4.0mm. Walmay Steel can be customized.
Walmay steel provides a variety of surface treatment methods such as bright annealing, wire drawing, sandblasting, and polishing.
