AISI 440B Martensitic Stainless Steel Chemical Composition Properties, Grade, Tables and Document

The AISI 440B is a high carbon austenitic and martensitic stainless steel and the attention is due to its excellent anti-corrosion and toughness characteristics. Its chemical composition usually has 0.75% to 0.95% carbon, 1% manganese, 1% silicon, 17% to 19% chromium, and 4% phosphorus. It is this grade which has got these advantages because of its high carbon content, which is made of wear resistance that actually makes it suitable for the cutting tools, bearings and the surgical instruments manufacturing. AISI 440B shows a good measure of stability and limited corrosion resistance in mild conditions. As global sociocultural interactions and influences become increasingly accessible, international relationships are shaped and deepened in multi-faceted and complex ways. This is achieved by heating of the metal to above the recrystallization temperature which leads to strain hardening. Engineers and manufacturers will often look to detailed tables, charts and PDF documents outlining its mechanical and chemical properties, in order to make sure to select the proper equipment and get the appropriate performance, in different industrial case.

AISI 440B Martensitic Stainless Steel Chemical Composition And Grade Table

AISI 440B is a steel alloy possessing ultra-high hardness and wear resistance making it ideal for very high-wear applications. The chemical combination generally involves 0.75% carbon, 1% manganese, 1% silicon, 17% chromium, 0.04% phosphorus, and 0.03% sulfur. This grade of stainless steel is very advantageous for mild corrosion resistance and toughness. It gives great flexibility to the product to apply different processes to it. It belongs specifically to the blades of knives, as well as to the surgical instruments and bearings. Upon proper heating treatment this kind of AISI 440B steel is able to reach really high levels of hardness and edge retention, therefore, it becomes the favorite choice for jobs in which endurance and sharpness are needed.
