Why can't stainless steel be flame cut? Flame cutting actually uses high-pressure oxygen flow to incinerate the metal and cut the metal. However, stainless steel has a high melting point and poor thermal conductivity. Under the influence of the temperature of the preheating flame, when flame cutting stainless steel, the stainless steel has a very thin oxide film on the surface of the stainless steel, which is called a high melting point. The high-viscosity chromium trioxide covers the surface of the stainless steel and prevents the next layer of metal from burning, so it cannot be cut normally.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between q345 steel plate price, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
