Introduction
Cast steel and stainless steel are two of the most common materials used in the industrial manufacturing, machine and structural engineering sectors. Both alloys have similar physical characteristics, and have unique strengths, making them an ideal choice for many applications. This paper will compare the mechanical properties of American standard low-temperature cast steel and stainless steel. The properties discussed are tensile strength, hardness, fatigue strength, and impact strength. The paper explains the properties and advantages of each metal and makes a comparison of them.
Tensile Strength
The strength of a metal is determined by its tensile strength. Tensile strength is the maximum force that can be applied to the material before it breaks or deforms. American standard low-temperature cast steel has a tensile strength of up to 66 ksi, while stainless steel has a tensile strength of up to 95 ksi. This makes stainless steel the stronger of the two metals.
Hardness
The hardness of a metal is determined by its ability to resist abrasion, impact and corrosion. Hardness is measured using the Brinell Hardness Scale. American standard low-temperature cast steel has a hardness range of up to HRC-30, while stainless steel has a hardness range of up to HRC-50. This makes stainless steel the harder of the two metals.
Fatigue Strength
The fatigue strength of a metal is its ability to withstand repeated loading and flexing before breaking or deforming. American standard low-temperature cast steel has a fatigue strength of up to 50 ksi, while stainless steel has a fatigue strength of up to 110 ksi. This shows steel to be the stronger of the two metals in this area.
Impact Strength
Impact strength is the resistance of the metal to shock and vibration. American standard low-temperature cast steel has an impact strength of up to 20 ft-lbs, while stainless steel has an impact strength of up to 30 ft-lbs. This indicates that stainless steel is the stronger of the two metals.
Conclusion
American standard low-temperature cast steel and stainless steel are both strong and durable metals which can be used in a variety of applications. Both alloys have similar physical characteristics and have unique strengths, making them an ideal choice for many applications. In terms of tensile strength, hardness, fatigue strength, and impact strength, stainless steel is the stronger of the two metals. This makes stainless steel the ideal choice when strength and durability is required.
