for constructions . because it have a high resistance for static load
Ths cost of tool steel is dependent on many factors including the alloy content and the manufacturing cost. Low alloy tool steels can be boought for less than $2.00 per pound. High alloy tool steels and high speed steels are sold for as much as $30.00 per pound. See the related links below for more information about the cost of tool steels
About a decade ago, a consortium of thirty-five steel companies worldwide undertook a massive programme to design, build, and test an UltraLight Steel Auto Body (ULSAB).W-1. ULSAB proved to be lightweight, structurally sound, safe, executable and affordable. One of the major contributors to the success of the ULSAB was a group of new steel types and grades called Advanced High Strength Steels (AHSS) (or ultra high-tensile steel). The main reason to utilize AHSS is their better performance in crash energy management, which allows one to down gauge with AHSS. In addition, these engineered AHSS address the automotive industry's need for steels with higher strength than conventional mild steels and enhanced formability. The DP (Dual phase) and TRIP (Transformation induced plasticity) steels may provide additional stretchability (but not bendability) compared to conventional steels such as HSLA steels within the same strength range. The CP (Complex phase) and MS (Martensitic) steels extend the strength range while maintaining the same formability. While the ULSAB proved these AHSS provided a major benefit to the automotive industry, these steels reacted differently from traditional higher strength steels in forming and assembly. Worldwide working groups within the WorldAutoSteel organization created the AHSS Application Guidelines (See the link below) to explain how and why AHSS steels were different from traditional mild and higher strength steels in terms of press-forming, fabrication, and joining processes for automotive underbody, structural, and body panels designed for higher strength steels.
Many stainless steels are stronger. It's also more corrosion resistant.
Any site of a major steel producer is a good site whether it is BHP Billiton, Kaiser Steel or similar
The endurance limit for steel, as a general term, flattens out at around 30ksi stress. As the cycles go to infinity, the endurance level for most steels stays above 25ksi stress.
Stainless steel is an Alloy steel because it contains chromium as an alloying element - steels without alloying elements are called carbon steels.
Copper and zinc are not alloying elements for steels.
Manganese is a key alloying element in many types of steel and stainless steels.
No. An alloy is an intimate mixture of 2 or more metals. Steels are actually regarded as being of 2 basic types - carbon and alloy. Carbon is an alloying element in carbon steels; there are other examples, such as: oxygen is regarded as an alloying element in zircaloy, silicon is an alloying element in aluminum and ferro-silicon, phosphorus in some types of bronze, etc. (not important if it is a metal or a non- metal).
The difference in classification of low alloy and high alloy steels is based on the metal composition: low alloy steels include a lower concentration of alloying metals versus high alloy steels. The composition affects properties like strength, ductility, etc.
carbon steels are steels which contain upto 2% carbon and some other trace elements such as silicon, manganese etc., Tool steels have greater amount of alloying than the alloy steels of iron. alloying elemnts include chromium, tungsten, molybdenum, carbon, vanadium, nitrogen in the form of nitrides, manganese, silicon, cobalt. These two mainly differ in the pattern in which they are manufactured. tool steels are manufactured from electric furnace techniques where as most carbon steels are manufactured from conventional melting processes. This is done to exhibit good alloy characteristics and impart greater refined structure which cannot be obtained from the conventional say a cuppola furnace or a bessemer furnace.
The metallurgical transfer motion behaviour during quenching is influenced by cooling rate, carbon concentrration , alloying elemnts and stress
normally it cover higher low and medium carbon steels without any other functional alloying elements. But mild steel is a very non-technical usage to describe any steel. Mostly they are defined by UTS and weldability, drawability etc.
High speed steel typically contains around 0.7-1.4% carbon. This carbon content helps improve the hardness and wear resistance of the steel, making it suitable for cutting tools and other high-speed applications.
If you are referring to stainless steel then one of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. The 'recipes' for making stainless steel are many and varied.
The main element used inmost of the cutlery is iron, base element of the steel alloy. Must have element is Carbon, otherwise it's not a steel. Stainless steel also contains Chromium, 14% or more. Other alloying elements include V, W, N, Co, Ni, Mo, Mn, etc. To see the effects of the alloying elements and detailed composition or most of the cutlery steels see the attached links. High end steels use more of the Vanadium, Molybdenum, Cobalt, Nitrogen, etc. Although, that doesn't mean simple low alloy steels will underperform for many uses.
Significantly oversimplifying things:cast iron is melted in an excess of oxygen to burn off the high levels of carbon that make cast iron brittlevarious alloying elements are melted into the iron to produce the desired grade of steel
