The process for metal stress relief is similar to flame hardening but the maximum temperature and cooling rates are different.Common methods for stress relieving carbon steel and alloy steel include Heating steel to 150-200 degrees Celsius after hardening relieves peak stresses and is used for components such as ball bearings.The differences between stiffness and strength in metalThe original shape is the flat sheet metal,and formed components need to retain their shape permanently.If the chosen sheet metal cannot be formed into the desired shape under the selected processing conditions,the applied stresses are higher than the tensile strength of the sheet metal,which causes cracks to form in the part.The Strength of Aluminum The Aluminum AssociationThe metal was widely used in the space shuttle program and NASA chose a high-strength aluminum-lithium alloy to make the new Orion spacecraft,which will someday take humans to Mars.U.S.Air Force After replacing older wood,steel,wire and fiber aircraft during WWII,high-strength aluminum alloys have become among the most commonly used

Mild Steel Due to fabrication issues,one cannot readily make use of less than 10 gauge mild steel plating (0.134 inch,or 3.5 mm).Even 10 gauge mild steel plating can be very problematic to keep fair.It will have much greater distortion levels while welding than plate of a greater thickness.Marine grade shipbuilding aluminum alloys4.Aluminum alloy has good cold and hot forming properties.Because the ship is manufactured by cold processing and hot processing,the marine grade aluminum alloy must be easy to form,does not produce crack defects,and can still meet the strength and corrosion requirements after processing.The selection of marine grade aluminum alloy is more stringent.Hydrogen Embrittlement of Steel - Industrial MetallurgistsHigh-strength steels with tensile strength greater than about 145 ksi (1000 MPa) are the alloys most vulnerable to hydrogen embrittlement.As mentioned earlier,exposure to hydrogen occurs during surface finishing process steps such as acid pickling and electroplating and during service if the steel is exposed to acids or if corrosion occurs.

Benefits The major advantage of aluminum in ship building is its strength to density ratio.Aluminum has high tensile strength with less weight,which results in lowering the weight of the overall structure and thus reduce the fuel cost.Aluminum vs Steel Comparing the Two 'Kings' of Metal CostRust and CorrosionStrengthWeightIts a common assumption that aluminum is cheaper than steel.Because after all,wouldnt soda cans be made of the cheapest metal possible for cost-savings benefits? Like all metals,the cost for steel and aluminum fluctuate depending on supply,demand and other economic factors.With that said,though,steel is typically cheaper (pound for pound) than its aluminum counterpart.See more on monroeengineeringSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextSteels for Shipbuilding IspatGuruNov 27,2015 Strength of steel and aluminium alloy ship plating under#0183;The normal high strength steels used for ship building have yields strength ranging from 315 N/sq mm to 490 N/sq mm and ultimate tensile strength of 440 N/sq mm to 740 N/sq mm.The area under the upper deck in crude oil tankers is exposed to mixed atmosphere of exhaust gas and H2S volatilized from the crude oil.Aluminum Strength vs Steel Strength - Kasten Marine1) Aluminum 5083 H-116 plate,as an example,has a yield strength of around 34,000 psi and an ultimate strength of around 45,000 psi.We can see that the plastic range of aluminum is considerably less than steel (around 11,000 psi plastic range for aluminum,or roughly 24%
