Which is better, martensitic stainless steel or 304 stainless steelStainless steel is divided into martensitic stainless steel, austenitic stainless steel, duplex stainless steel, etc. We commonly use austenitic stainless steel 304 and 316, these two grades of materials have good anti-corrosion and anti-rust properties, but relatively low tensile strength. The commonly used grades of martensitic stainless steel are 1CrCrCr17Ni and so on. The anti-corrosion and anti-rust performance of martensitic stainless steel is worse than that of austenitic stainless steel. However, martensitic stainless steels can be quenched and tempered to improve the mechanical properties of the product. The tensile strength of martensitic stainless steel can reach more than 1100MPa after modulation. Therefore, martensitic stainless steel and 304 stainless steel have their own advantages and disadvantages, and which is better depends on the needs and use.
If you need a material with good anti-corrosion and anti-rust properties, you can choose 304 or 316 austenitic stainless steel. These two materials have a wide range of applications in many fields, such as food, beverages, medical devices, chemical industry, marine engineering, etc.

If you need a material with higher tensile strength and better mechanical properties, you can choose martensitic stainless steel. After quenching and tempering, the tensile strength of martensitic stainless steel can reach more than 1100MPa, which is much higher than that of austenitic stainless steel. Therefore, in the occasion that needs to withstand greater stress, such as construction, bridges, paper industry, etc., martensitic stainless steel is a better choice.
