Chemical composition of AISI 430 steel and its main technical characteristics:
Chemical composition:
- Chromium (Cr): 16-18%
- Carbon (C): Less than 0.12%
- Silicon (Si): Up to 1%
- Manganese (Mn): Up to 1%
- Phosphorus (P): Up to 0.04%
- Sulfur (S): Up to 0.03%
Main technical characteristics:
- Maximum corrosion resistance among stainless steels.
- Good workability and formability.
- Excellent strength and durability at relatively low manufacturing costs.
- Complies with AISI (American Iron and Steel Institute) standards for ferritic steels.
Therefore, AISI 430 steel is characterized by high corrosion resistance, good workability, and excellent strength, making it a popular material in various industries.
The chemical composition of AISI 430 steel includes small amounts of carbon (up to 0.12%), silicon (up to 0.8%), phosphorus (up to 0.035%), and other chemical compounds in minimal quantities. The main elements are iron (approximately 81%) and chromium (16-18%), which determine the key operational properties of the material.
Among the main technical characteristics of AISI 430 steel are:
- Tensile strength ranges from 450 to 600 MPa, and compressive strength is approximately 240 MPa.
- Yield strength is 360 MPa.
- Hardness according to the Brinell scale (HB) is approximately 160 units.
- Density corresponds to 7800 kg/m³, which is a typical value for most types of stainless steels.
The balanced chemical composition and high operational characteristics of AISI 430 steel are among the key advantages of this material. The absence of expensive components contributes to reducing the cost of the alloy, making it very popular in many industries.
AISI 430 stainless steel is widely used in various industries due to its high corrosion resistance, mechanical strength, and resistance to the effects of chemically active compounds. The high chromium content in this alloy allows it to be used not only in technical fields but also in the food industry. This grade of steel is one of the few in food-grade stainless steel that can withstand high mechanical and temperature loads simultaneously.
Applications of the material in various industries:
- Petroleum industry: main pipelines, installations for the transportation and transfer of natural gas and petroleum products.
- Food industry: utensils and accessories, work surfaces and tables for professional kitchens, distillers, distillation cubes.
- Construction: facade panels for decorative cladding of buildings, decorative elements.
- Chemical industry: containers for the transportation and storage of diluted acids (nitric, citric, acetic), laboratory equipment.
- Mechanical engineering: shafts, bushings, connecting elements of various designs, details of mechanisms operating in conditions of high humidity or aggressive environments.
AISI 430 is a versatile steel grade with optimal technical and operational parameters.
Despite being developed in the United States, there is a Post-Soviet analogue of AISI 430 - stainless steel 12Х17, which has a similar composition and technical characteristics.
