403 ss smls pipe

Stainless steels are high-alloy steels that have good corrosion resistance due to the large amounts of chromium contained in these steels. Most stainless steel contains about 10% chromium.

Stainless steel can be divided into three categories based on crystal structure. These groups include martensite, austenite and ferrite. The combination of martensitic and ferritic steels forms the fourth group of stainless steels, called precipitation-hardened steels.

This straight chromium stainless steel offers reasonable corrosion resistance and high mechanical characteristics. The 403 Series offers heat resistance and a scaling temperature of about 1300°F. It is a corrosion and heat resistant 12% Cr martensitic stainless steel. This alloy offers a wide range of mechanical properties that are obtainable by appropriate heat treatments. It is easily hardened by oil, fan or air cooling and may be tempered at temperatures of up to 1350°F (732°C) to improve fracture toughness. Oil or fan cooling is required in thicker sections

product feature

403 stainless steel is a martensitic stainless steel with high chromium content and low carbon content. Also known as UNS S40300, it is commonly used in applications requiring high strength and corrosion resistance, such as industrial equipment, automotive parts, and aerospace components.

application

The chromium content in 403 stainless steel provides excellent corrosion resistance, making it suitable for use in harsh environments. It also has good mechanical properties, including high hardness, toughness and wear resistance. However, it is not as corrosion-resistant as other stainless steels such as 304 or 316 and may not be suitable for use in highly corrosive environments.
