Q:what caused my stainless steel sink to get rust spots?
Stainless Steel is the marketing name. For truth in advertising, it should be called Stain Resistant Steel. It should be easy to scrub rust away with an SOS or Brillo pad. To prevent rust from recurring: * thoroughly rinse all chloride containing soaps away * scour the sink at least weekly to remove any residues * if the water source has high mineral content—especially iron—more frequent sink scouring is needed, plus towel drying the sink. * don't allow salt to remain in the sink—rinse it out
Q:Is Carbon Steel a Metallic Material?
yes its iron with carbon in it

Q:melting point of 1008 steel?
It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel. Minimum Properties Ultimate Tensile Strength, psi 43,900 - 51,900 Yield Strength, psi 26,100 - 34,800 Elongation 42 - 48% Chemistry Iron (Fe) 99% Carbon (C) 0.08% Manganese (Mn) 0.6% max Phosphorus (P) 0.035% max Copper (Cu) 0.2% min Sulfur (S) 0.04%
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:Heat treatment of mild steel? Process description macro-micro
Mild steel is a solution of carbon within iron, etc. When the steel is very hot the carbon is well distributed. As the steel is cooled iron crystals form excluding the carbon that will then collect at the boundaries (grain boundaries) between iron crystals. If cooling is rapid at any point in the cool down crystal growth will cease (affecting final grain size and the mix of carbon and iron at the grain boundaries). The ductility or hardness of the resulting steel will be determined by the grain sizes and makeup of the carbon/iron mix between grains. Ductile iron permits 'slabs' of iron to slip past each other within iron crystals and location of carbon atoms may help prevent slip resulting in hardness. Therefore, heat treatment usually consists of 'soaking' the steel at a temperature high enough to dissolve all the carbon uniformly then cooling it down slowly or rapidly to obtain optimum grain size and interstitial carbon between grains to obtain desired properties.
Q:What makes Steel stronger than Iron?
Cast Iron' is typically brittle, while 'Maleable Iron' has a small percentage of carbon which allows it to be hammered and formed. Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron. Steel is a crystalline structure of iron molecules interspersed with carbon molecules. This is properly known as cementite. The hardness and malleability of steel depends not only on the carbon content, but on how the carbon and iron molecules are arranged to one another. Internal stresses in the steel's crystalline structure will increase or decrease depending on the temperature it is subjected to and the rate at which molten steel is cooled. This 'tempering' can increase the strength of the steel at the expense of brittleness.
Q:I have a question in alloy steel?
Steel is basically an alloy of iron and carbon that has more than 0% carbon and less than 2% carbon. The alloy of carbon and iron with more than 2% carbon is considered cast iron. The bessemer process converts cast iron to steel by injecting oxygen into molter cast iron to burn off the excess carbon. Steel is also modified by adding additional elements like silicon, molydenum, vanadium, chrome, etc.
Q:Steel I-beam for header?
First of all is it a rule of thumb with carpenters and ironworkers never to set steel on wood. I would use a 14 tall (2) ply lvl header. *Laminated veneer Lumber. This will hold the weight of the structure between your posts. A steel beam would be quite costly today as prices on steel have skyrocketed, plus you would need a boom truck or small crane to set this beam, and you would need some sort of mounting bracket or holes pre-drilled in the beam ends to secure it to the posts. Plus you would need to have the beam delivered and if your patio is in the backyard - you would need another pc.of equipment to get it around back. Advice from me is to go with an LVL beam. They are 1+3/4 Thick and you would need a (2 ply ) beam, which means you set one pc. and then laminate another one into the first. Glue between layers (use heavy duty liquid nails) and then Lag screw them together. Use 5/16 x 3 lag screws with a washer on each one. Pre-drill holes about 3/16 smaller than lag screws - then insert lag screws and tighten up with an electric impact.
Q:Does steel have water in it?
Steel contains no water; any water that you see is condensed out of the air.
