The shipbuilding area needs a large amount of stainless steel, and nickel alloy steel products especially the tube and fitting for corrosion of the seawater. And Stainless steel 304,316L is the most widely used material in ship construction. They have a very good performance against chloride corrosion and also provide a good choice for saving basic costs.
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.
