AISI 440 stainless steel sheet & plate

440 steel is a martensitic stainless steel. The carbon content is 1.0%, and the chromium content is 16-18%. Strong anti-rust ability, high-quality stainless steel, 440 is high-strength knife steel, slightly higher carbon content, can obtain higher yield strength after proper heat treatment, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common application example is “razor blades”. There are three commonly used models: 440A, 440B, 440C, and 440F (easy to process)

440 stainless steel is a type of high carbon martensitic stainless steel that offers excellent hardness, wear resistance, and corrosion resistance. It belongs to the family of stainless steels that contains a high percentage of carbon (between 0.6% to 0.75%), which contributes to its hardness and strength.

Some of the key properties of 440 stainless steel include:

Hardness: 440 stainless steel has a high level of hardness, making it ideal for use in applications that require resistance to wear, abrasion, and deformation.

Corrosion resistance: 440 stainless steel offers good corrosion resistance, although it is not as corrosion-resistant as austenitic stainless steels.

Magnetic properties: 440 stainless steel is magnetic, which makes it suitable for use in applications where magnetic properties are required.

Toughness: 440 stainless steel has good toughness, which means that it can withstand impact and shock without cracking or breaking.

Some of the common applications for 440 stainless steel include:

Cutlery and knives: The high hardness and wear resistance of 440 stainless steel make it ideal for use in cutlery and knives.

Bearings and valves: 440 stainless steel is often used to make bearings and valves because of its high strength and resistance to wear and corrosion.

Pumps and turbines: The toughness and resistance to wear of 440 stainless steel make it suitable for use in pumps and turbines.

Overall, 440 stainless steel is a versatile and high-performance material that offers excellent hardness, wear resistance, and corrosion resistance. It is well-suited for use in applications where these properties are required, such as in cutlery, bearings, valves, pumps, and turbines.

Here are some of the most common international standards for 440 stainless steel:

ASTM A276: Standard Specification for Stainless Steel Bars and Shapes

ASTM A580: Standard Specification for Stainless Steel Wire

JIS G4303: Stainless steel bars

EN 10088-3: Stainless steels – Part 3: Technical delivery conditions for semi-finished products, bars, rods, wire, sections and bright products of corrosion resisting steels for general purposes

GB/T 1220: Stainless steel bars
