Mechanical Properties of AISI 305 (1Cr18Ni12) at Room Temperature
Austenitic steel AISI 305 (1Cr18Ni12) is a common grade of stainless steel and is reinforced by alloying chromium and nickel. This material is generally non-magnetic, but will become slightly magnetic when cold-worked. It can generally be used for sheet and other applications at room temperature. This material has some excellent mechanical properties that make it suitable for use in a wide range of applications.
Tensile strength:
The tensile strength of this material is 205MPa, which is much higher than many other materials such as aluminum or mild steel. The excellent strength of AISI 305 makes it very popular in applications that require strength or durability at room temperature. This material is often used in applications such as boiler and pressure vessel components, food-processing equipment, kitchenware, and medical components that require high strength and durability.
Yield strength:
The yield strength of AISI 305 at room temperature is 190MPa, which is quite high compared to other materials of similar density. This property is advantageous in engineering applications that require components to resist deformation under heavy loads or shock loads.
Elongation:
The elongation of this material is 40%, which is higher than many alternative materials, such as aluminum or mild steel. This means that components made of AISI 305 are highly resistant to tearing and cracking when subjected to forces that would cause other materials to break. This property makes it an ideal material for use in applications that require components to maintain geometry and form.
Ductility:
AISI 305 has excellent ductility, which is a measure of how easily it can be formed and manipulated into different shapes. This makes it an ideal material for forming components, such as kitchen and medical utensils, and other components that need to be formed and shaped into precise geometries.
Hardness:
The hardness of this material is around 95-110 HB, which is higher than many other materials, such as aluminum and mild steel. This property makes this material ideal for components that need to resist abrasion and wear despite heavy use, such as saw blades and cooking utensils.
Corrosion resistance:
The corrosion resistance of this material is very high due to the addition of chromium. Chromium provides passivation layers that prevent stainless steel from corroding. AISI 305 is therefore an ideal material for components that need to remain corrosion free under hostile environments, such as food-processing equipment, medical components, and components used in the offshore oil and gas industry.
From the above, it can be seen that AISI 305 offers a range of properties that make it suitable for a wide range of applications. This material is strong, durable, ductile, corrosion resistant and hard, which makes it ideal for components that need to be strong and reliable despite being subjected to shock loads, heavy loads, and hostile environments. In addition, the ease with which AISI 305 can be shaped and formed makes it an ideal material for components that require precise geometries.
