Q:PLS tell me all Foam Steel Characteristics and use?Thanks: Foam steel [often steel foam] is used in applications that require light weight but high rigidity and strength. Watertight doors on modern ships are often made of foam steel. Pressure doors on aircraft are possible uses. As we keep striving for lighter weights in cars, foam steel might have some useful applications in bodies. There is a technical paper online that is in .pdf format that has a good discussion of the process and characteristics of foam steel.

Q: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 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).

Q:How are steel coils used in the production of oil and gas machinery?: Steel coils are used in the production of oil and gas machinery to create various components, such as pipelines, storage tanks, pressure vessels, and drilling equipment. The coils are typically shaped and welded to form these structures, which provide the necessary strength and durability required for the demanding conditions of the oil and gas industry.

Q:How are steel coils used in the production of steel containers?: Steel coils are used in the production of steel containers by being processed and shaped into the desired form. These coils are unrolled and cut into specific lengths, which are then formed into the shape of the container. The coils provide the necessary material and strength to create durable and sturdy containers for various industries such as shipping, storage, and manufacturing.

Q:I'm doing a commercial for chemistry and I need to know any kind of chemistry dealing with Callaway Big Bertha Irons. I know they are stainless steel but any more info would help out! Thank you! :): Stainless steel is a mixture of metals, each metal is included in order to make up for each others weaknesses. Each metal is included due to a property that is benificial in some way, for instance Chromium is included because it makes the stainless steel 'stainless'. In chemistry a mixture of metals, stainless steel, is called an alloy.

Q:What are the different methods of coil end welding for steel coils?: There are several different methods of coil end welding for steel coils, which include resistance welding, laser welding, and electric arc welding.

Q:this is for a school project due morrow can u please answerwhat are disadvantages of stainless steelplease also show were u got info ty: it sometimes rusts

Q:What is the difference between cold rolled strip and cold rolled steel coil?: Cold rolled steel strip: the width is below 900mm! Cold rolled steel coil: the width is above 1000mm! Materials and purposes are not very different, basically the same!

Q:I know that steel wool is coated with... something... that protects it from rusting. I need to know what that is, and how to get it off.: spun steel fibers have a microscopic coating of oil to prevent them from rusting. Rusting steel wool wouldn't sell very well. I would think that removing this oil could be accomplished with any good degreaser, like brake cleaner or the like. However, I've never tried this before. In science class they perform experiments by removing the oil with vinegar. After wringing out the steel wool pad, it is wrapped around a thermometer and placed in a sealed jar. After a few minutes the temperature rises because of the chemical reaction that takes place when four atoms of iron react with three atoms of oxygen and create two atoms of iron oxide - RUST! You can unwittingly recreate this experiment by using steel wool in the process of removing one or more layers of finish from a piece of furniture Hope this helps
