316/316L stainless steel plates
Both 316 and 316L stainless steel plates are austenitic stainless steels, with their core alloys being chromium (Cr ≥ 16%) and nickel (Ni ≥ 10%). The key difference between the two lies in their carbon content: 316 stainless steel has a carbon content of ≤ 0.08%, while 316L stainless steel (the "L" stands for "Low Carbon") has a carbon content of ≤ 0.03%. This carbon content difference is not only the core difference between the two, but also directly affects their intergranular corrosion resistance and weldability, providing a clear basis for selection in different application scenarios.

Hot Processing
Seamless Pipes: Hot piercing + multiple mandrel mill or rotary piercing steps.
Welded Pipes: Plate is rolled into a cylinder, welded, and then sized/straightened.
Features:
Seamless pipes are axially stretched from the billet, with strict control of wall thickness and diameter.
Heat processing of pipes requires extra attention to roundness and uniform wall thickness.
Welded pipes need careful control of weld seam position and stress in the heat-affected zone.
Stress Characteristics:
The circular cross-section generates hoop and axial stresses during heating and cooling, which must be relieved by annealing.
Annealing: After hot rolling or welding, 409 stainless steel pipes are annealed at approximately 800–900°C to relieve internal stresses, improve ductility, and enhance corrosion resistance. The pipe is then cooled under controlled conditions to stabilize dimensions and shape.
Stress Relief Annealing: For formed or welded pipes, a short low-temperature anneal below 400–450°C is often applied to remove residual stresses caused by welding or bending.
Notes:
Annealing is essential for 409 ferritic stainless steel due to its lower ductility and corrosion resistance.
Processes such as solution treatment, precipitation hardening, or high-temperature tempering are not applicable to 409 stainless steel pipes.
