— Mild steels or low carbon steels may be classified as follows:
(i) Dead mild steel — C 0.05 to 0.15%.
Dead mild steel is used for making steel wire, sheets, rivets, screws, pipe, nail and chain.
It has a tensile strength of 390 N/mm2 and a hardness of about 115 BHN.
(ii) Mild steel containing 0.15 to 0.20% carbon has a tensile strength of 420 N/mm2 and hardness 125 BHN.
It is used for making camshafts, sheets and strips for fan blades, welded tubing, forgings, drag lines etc.
(iii) Mild steel containing 0.20 to 0.30% carbon has a tensile strength of 555 N/mm2 and a hardness of 140 BHN.
It is used for making valves, gears, crankshafts, connecting rods, railway axles, fish plates, small forgings etc.
what is the most suitable gas pressure to cut 2mm mild steel 1020 by using CO2 laser cutting machine?power and feed rate are 2500Watt and 1700 mm/s.pls answer me ya.
I know when welding aluminum it requires argon gas. But I only weld once a month for small projects is it okay to use argon gas while welding with mild steel with steel flux?
Mild steel is 25mm wide x 6mm thick, I have tries but it keeps leaving flat areas
Harvey, I do know the difference I have been making gates, trellises, balconies etc. for 20 years.
I would like to know the yield strength of Mild steel and galvanized iron. Also can Mild steel pipes be used for compressed air applications with pressures ranging from 2 bar to 12 bar?
What would the thickness of the metal need to be if I use a hollow mild steel tube, between 3 cm to 4 cm in diamter and 190 cm long, horizontal and supported at its ends, in order to hang 400 lbs in the middle without it bowing?
what is the recrystalization temperature of mild steel or a paperclip?
i need this for a physics assignment and cant seem to find it anywhere
thanks jayden
I currently run a 3000 watt Hankwang laser and I am told that I can cut 11ga mild steel with nitrogen. What should I set my cutting conditions to and what size nozzle and gas pressure should I use?
What are the environmental and social impacts of mining, processing and using steel?
this is my engineering work and i cant seem to find an answer its really important and i have no idea about drilling a hole in mild steel bar never learnt or done it and its due in tommorow!!!
I need to know what height of mild steel I beam I should get to hold 1 tonne of weight. The beam will be 2.3 meters long. Is there a site that shows calculations for this?
How do you identify if the given sample piece is mild steel, cast iron or cast steel ?
Thereby which electode will you use for welding of each of the above metals ?
