- Q:Which steels were origianally designed to be used to cut and shape metals and other materials?- alloy steel- high carbon steel- carbide steel- tool steelthanks
- Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.
- Q:Is 440 steel relatively strong or weak?
- Its strong steel is rated by the precence of carbon in it. Higher carbon _ higher the price

- Q:Many gerber knives are made out of what gerber calls high Carbon steels and I was wondering if anyone knew exactly what is this mysterious steel.
- A steel knifeblade is like a box full of a million ball bearings. The molecules pile up/line up just like those ball bearings. When it's pure, though, you can easily deform it....just like you can ram your hand down into that box of ball bearings. What happens if you pour a gallon of heated wax over those bearings, though? It fills the gaps between the molecules and solidifies the entire mass into one solid shape. If you smack it then, you'll break your hand. It'll hold its shape *much* better and longer. That's pretty basic but what do you expect at 04:00? ;) Addendum: At one time, in the late 80's to mid 90's, it was 440a...they then switched to 440c on their mass market stuff and 154 on their special runs....late 90's-2005 went to all 440c....today's knives are a mix of 440c and some pricier knives sporting S30V blades. If it's Gerber and it costs less than $40 today, 99% of the time it will be 440c.
- Q:How are steel coils used in the production of electrical devices?
