Q:how does steel become stainless?
The person above me is right .The stainless steel is used in shaving blades
Q:Buy a steel building!!!!?
Here is a web search of the term steel building specification. It should give you some ideas and sources.
Q:How to repair corten steel?
6010 and 6011 Electrodes for welding galvenized steel. Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating. For welding corten steel: 1A.W.S ClassificationE 7018 - 1AWS A 5 - 1 - 78 2IS classificationE 5424 JXIS 814 (Part I II)H 3BS classificationE 51.54 B 12 17HBs 639 - 1976
Q:Copper pots....tin or stainless steel lined?
Stainless steel is durable and does not disolve and make things taste funny. Stainless steel is not a good conductor of heat, so it has hot and cold spots. Copper is very good conductor. They noe bond copper to stainless steel to get the best features of each. Some pots just have a very thin copper plating to fool you. A good pot will be heavier, It is really hard to tell from looking.if it is plating or a bonded layer of copper. the thicker the better
Q:manufacturing process of steel containers?
There are many types of steel containers and many different mnfg processes. There are also thousands of different steel alloys. Steel is used for canned food, compressed air cyclinders, hydraulic pressure vessels, electrical boxes, and many other containers. Steel containers are made out of sheet metal by soldering, brazing, spot welding, seam welding, riveting, bolting, screwing, etc. Heavier wall containers are fabricated of plate steel. Some steel containers are made by deforming the steel by extruding, forging, spin forming, drawing, ironing, etc. Some steel containers are made by machining. You should be able to find plenty of references if you search for these terms. good luck
Q:REAL steeled boned corsets?
Hi, okorder.com/ There are 3 types of corsets: Fashion corsets, Authentic corsets and Waist training corsets. The fashion corsets are designed for light enclasping of body. They are made with plastics bones usually. The authentic corsets can reduce your waist size about 4 - 5 and the waist training corsets about 6. They both are made with steel spirals and flat bones. The waist training corsets are recommended for experienced wearers only. Look on info pages of the seller. The corsets reinforced with plastic bones are cheap with low durability.
Q:Best affordable steel combat knife?
Sorry, probably aint gonna happen in that $ range. How big of a blade will effect the steel selection. For instance I have one I forged from 52100, a most excellent steel better suited for 5-6 blades. For larger blades either 5160 or L-6 can make an indestructable blade. For 5 and under D-2 is about as fine a steel as you can get. No blade made from these will come cheap, L-6 is only available from custom makers. Save up your money, expect to pay 100 - 200 for a well made blade. You pay cheap prices you get cheap workmanship.
Q:Questions about Steel. Please Help?
Steel is an alloy composed mainly of iron and carbon, but almost always contain small and various amounts of other elements. So all of these questions will have a range of answers. For example, the density of steel is between 0.280 and 0.291 pounds/cubic inch. The melting point for mild steel is around 2400F (1300C), but can be much higher, as in stainless steel which is 2800F because it contains a minimum of 11% chromium. Wiki has a legitimate definition.
Q:quinching steel... hardening?
boy what a though question ! let me explain. when you rapidly cool a steel from high temperatures(depending on steel type) with water or oil or other means , it is called quenching. it depends on the steel type to say if it is better to quench it with oil or water but basically in water you will have a harder steel rather than oil. for some steels if you do this you will ruin it's properties ! you can't totally tell what kind of steel do you have until you get it analyzed with Quantometer analyzer with a pocket knife it is more like an estimation and it can't be trust able generally if you can scratch the steel with your knife it means it is not a hard steel and it might not be expensive. I hope that helps but for more information i need to know more !
Q:Aluminized Steel same with Stainless Steel 409 & 430?
Stainless steel 400 Series—ferritic and martensitic chromium alloys Type 409—cheapest type; used for automobile exhausts; ferritic (iron/chromium only) Type 430—decorative, e.g., for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance. Today, almost all bulk metal materials that are referred to loosely as aluminium, are actually alloys. For example, the common aluminium foils are alloys of 92% to 99% aluminium. Aluminized steel Type 1: 1xx.x series are minimum 99% aluminium
