i mean the properties include the elasticity, impact load and ductility. am doing assignment about the perfect material that should be possessed by spring and i found alloy steel is the perfect and am confused whether stainless steel is the same with alloy steel ?
Alloy Steel Vs Stainless Steel
Alloy steel is a stainless steel. The differences between the two are the composition of the metal. Alloy steel is steel with usually less than 5% of other elements, like molybdenum, copper, chrome while stainless steel is a steel with at least 10-11% of chromium.
Is Stainless Steel An Alloy
*Alloy steel is not same as stainless steel. An alloy steel is not the perfect spring steel. Since you are doing the project, please understand the carbon steel,alloy steel and super alloys. Alloy steel is steel alloyed with a variety of elements in amounts of between 1 and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. Stainless steel is a type of high alloy steel. *As far as spring material is concern , spring steel or music wire is best suited. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant bending or twisting. Silicon is the key component to most spring steel alloys. An example of a spring steel used for cars would be AISI 9255 (DIN and UNI: 55Si7, AFNOR 55S7), containing 1.50%-1.80% silicon, 0.70%-1.00% manganese and 0.52%-0.60% carbon. Most spring steels (as used in cars) are hardened and tempered to about 45 Rockwell C. Since sufficient links were given earlier but I like you to go through spring steel as it is your subject matter. I have done the project on The design of a helical compression spring selected material was ASTM A228 (0.80–0.95% carbon).
