Product Description:

CS/DS/DDS/EDDS COLD ROLLED STEEL

Brief Introduction

Cold Rolled Steel is steel that has been worked below itsrecrystallization temperature by passing it between a pair of rollers.Recrystallization temperature is the temperature at which grains in the latticestructure of the metal have been rearranged, leaving it free of strain anddeformations. Cold Rolled Steel is pre-treated before being cold rolled with aprocess known as pickling, which uses strong acids to remove scale and otherimpurities. The Cold Rolled Steel is then passed through rollers to reduce itsthickness. Most cold rolling takes place in multiple passes and as the size ofthe Cold Rolled Steel is further reduced, its strength and hardness bothincrease, but its ductility decreases. After cold rolling, heating the metal upin a process known as annealing can restore some of its ductility. The finalCold Rolled Steel may be manufactured in the form of sheets, strips, bars, orother forms.

Application

It’s widely used in outdoor and interior decoration, furnishingmanufacturing, home appliance, automobile etc.

Q:What are the components of Stainless Steel?
The basic ingredient is from 11%-30% chromium, however in many stainless steels nickel or manganese are important secondary ingredients. There are two basic types of stainless steels: 1)austenitic stainless steels, and 2)ferritic stainless steels. In austenitic SS the important ingredients are Chromium and Nickel. (Chromium and manganese are occasionally use instead of nickel.) It's important to note that many austenitic SS's contain almost no carbon, so by some definitions they are not steel at all but iron/chromium/nickel alloys. the additions of nickel (or manganese) actually changes the crystal structure of the iron, so the properties of these types are quite different from normal carbon steels. Austenitic SS have very good to excellent corrosion resistance, and fairly good heat resistance. In ferritic stainless steels, the important ingredients are chromium and carbon. Ferritic stainless steels have markedly greater strength than austentitic types. However since they contain less chromium than austenitic types they are only moderately corrosion resistant and are much less heat resistant. Without the addition of nickel and/or manganeese adding more than about 20% chromium tends to make the steel brittle. Most stainless steel is melted under an inert argon atmosphere in an airtight furnace. Melting stainless in open air would preferentially oxidize the chromium, forming slag which would float to the surface of the steel, thus reducing the chromium content. Chromium also tends to react with nitrogen in the air at high temperatures, exposure to nitrogen tends to cause brittleness in stainless steels. As long as the manufacturer keeps careful control of the composition of the metal and the level of impurities during melting, stainless is endlessly recyclable.
Q:Angular Velocity of a Steel Ball after a Collision?
You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...
Q:Stainless steel?
No they can not, it depends on the type of finish the stainless steel has. They do make a product called never dull. It is a polishing cloth that will soften the metal as it polishes.
Q:how to make carbon steel?
in the experience that your speaking a pair of folding pocket knife, i think of that it somewhat is somewhat six one way and a 0.5 dozen the different. i actually do choose stainless for my pocket knives. i don't choose to grease a knife to the degree i've got faith carbon demands, basically to then stick it my pocket to entice dirt to the knife and oil to my pants. i'm the impressive opposite on sheath knives nevertheless. i admire 1095 carbon steel, uncomplicated part sheath knives. i will thrash on them difficult, and that i rarely have considerable part issues. of course, I require them to be lined with some style of powder coat or the like, with the aid of fact they might rust, yet I do attempt and save them sparkling and dry whilst in the sheath, so as that they gained't pit the uncoated part. My motives for this sheath knife selection is multi-fold. First, those knives are only much less costly. i don't spend $80 money on a exterior sheath knife. i take advantage of the gadget too difficult to choose to spend extra. i don't basically like the extra classic stainless steels alongside with AUS-8, 420HC, and 440C (to not point out the HORRENDOUS 440A) with the aid of fact i've got faith that the all else being equivalent, a stainless blade will bend till now a carbon blade will harm. I additionally think of that carbon holds an part a minimum of besides, if not extra suited, than classic stainless, and it somewhat is plenty extra handy to hone. i don't understand plenty approximately those new laminates, different than the very difficult, yet not so difficult. they seem probably too brittle for my use. That, mixed with the actuality that they harm the bank, ability that I only is only not pondering them.
Q:Danielle steel..................................................................?
No they are a good read.
Q:Buy a steel building!!!!?
A steel storage garage?? Proper ground preparation---steady level ground--and lots of friends to help erect it.
Q:Is Steel a Pure Substance or a Mixture?
Scott, there are 3 types of materials: elements, compounds, and mixtures. Compounds are covalently bonded elements. Compounds and elements are both considered 'pure' substances. Mixtures are not bonded in any fashion. So a steel mixture can have varying amounts of iron, carbon, silica,molybdenum, etc., giving the steel the desired properties (strength, rigidity, rust resistance, etc.).
Q:Cleaning granite and stainless steel?
I just use my Method brand dish soap to clean my stainless fridge. Then polish it with a dry soft cloth. Then it also smells like cucumber when I'm done. :-)
Q:Carbon Steel strength grading?
Yes. Most high quality knives are made of carbon steel versus say stainless steel. High strength carbon steel holds an edge well and is strong.
