AISI 501 Martensitic Stainless Steel Chemical Composition, Grade, Tables and PDF Online

This AISI 501 Martensitic Stainless Steel is marked by its high chromium content, which has an excellent reputation for corrosion resistance and great strength. For the most part, it consists of chromium, carbon, and some other minor elements, including manganese, silicate and sulfur, and due to this, its chemical composition makes it very strong. On top of that, this grade is commonly selected in cases of demanding durability, for example, that required in bearings, surgical instruments, and valve components. The AISI 501 has high resistance to different corrosive environments and it can operate in elevated temperatures. Its carbon-manganese content gives it a martensitic structure, which allows it to be hardenable via heat treatment thus, providing it with a much higher strength and wear resistance. Having the whole chemical structure, and its properties, the engineers will be in a good place to employ the AISI 501 in variety of industries.

AISI 501 Martensitic Stainless Steel Chemical Composition And Grade Table

AISI 501 is a martensitic stainless steel which due its superior corrosion resistance and high strength is famous. Its chemical composition makeup generally is about 0.15 carbon, 1 manganese, 1 silicon, 16.00-18.00 resting on chromium, and a smattering of other components like phosphorus and sulfur. This alloy has impressive mechanical properties and can be hardened through heat treat processes. As AISI 501 has a variety of uses ranging from the automotive and aerospace to the manufacturing industries. Its corrosion resistant feature in combination with its strength makes it the most ideal material to be used in components exposed to harsh environments and tough conditions.
