Introduction
1.30Cr13 stainless steel is a martensitic stainless steel material, belonging to AISI430 steel, its national standard designation is GB/T1220-2007. In addition to containing Cr and C , it also contains a small amount of Mn, Si, P and S elements, which endows it with good corrosion resistance, rust resistance, hardenability and machinability, and is also one of the commonly used stainless steel in life.
2.30Cr13 stainless steel mainly contains 13% chromium, which is effectively ensuring that 30Cr13 stainless steel has the characteristics of general AISI430 steels. Other alloy elements such as manganese, silicon and phosphorus can improve the toughness and welding performance of 30Cr13 stainless steel.
Applications
1. 30Cr13 stainless steel is mainly used in the production of various knife blades, small magnets and springs, due to its excellent corrosion resistance, rust resistance and wear resistance.
2. 30Cr13 stainless steel is also widely used in the production of kitchen utensils, plate cuttings and medical instruments, due to its good hardenability and machinability.
3. 30Cr13 stainless steel is used in many fields due to its good corrosion resistance, including food industry, medical industry, chemical industry, etc.
4. 30Cr13 stainless steel is also used in some outdoor spaces, such as outdoor columns, railings and other places that require higher anti-corrosion performance.
Advantages
1. 30Cr13 stainless steel has excellent rust resistance, corrosion resistance and wear resistance, so it is usually used in the production of kitchenware and various cutting tools.
2. 30Cr13 stainless steel has good mechanical and processing properties and is particularly suitable for production of components that require higher hardness.
3. 30Cr13 stainless steel has no temper brittleness, therefore it can be cold-heated and cold-processed without thermal deformation.
4. 30Cr13 stainless steel has a low cost performance and can be used in a wide application range.
Disadvantages
1. 30Cr13 stainless steel has weak acid resistance and poor atmospheric corrosion resistance and cannot be used in environments with acid.
2. 30Cr13 stainless steel has poor heat resistance, and its maximum working temperature is only 530 degrees Celsius.
Conclusion
30Cr13 stainless steel is a kind of martensitic stainless steel, belonging to AISI430 series, mainly containing Cr, C, Mn, Si, P and S elements. It has the characteristics of good corrosion resistance, rust resistance, hardenability, machinability and low cost performance. It is widely used in the production of kitchen utensils and all kinds of cutting tools. However, its acid resistance, heat resistance and atmospheric corrosion resistance are poor. Therefore, it is not suitable for use in hot and acidic environments.
