Stainless steel has heat resistance, high-temperature resistance, low-temperature resistance, and even ultra-low temperature resistance. Depending on the type of stainless steel, the mechanical properties are different. Martensitic stainless steel has high strength and hardness and is suitable for manufacturing parts that are not only corrosion resistant but also require high strength and high wear resistance. The strength is not high, but it is resistant to oxidation. Suitable for all kinds of industrial furnace parts.
