150 degree. When I was involved with submarine construction the metal was preheated 150 F to 200 F depending on the thickness. Interpass temp was 300 F max.

What is difference between preheat and interpass temperature in welding?
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.
Is carbon steel the same as mild steel?
both of these are same In some places they are used interchangeabl low carbon steel has 0.05-0.15% carbon mild carbon steel has0.16-0.29% carbon http://www.metalsupplies.com/
Where was carbon steel first used?
According to my calculations, Carbon Steel was used thousands of years ago, because, if carbon steel swords were invented thousands of years ago then- heres a question: if carbon steel swords was invented back then, then what made carbon steel swords? the same thing we use to make carbon steel, which is mainly carbon and iron. The carbon, when mixed with molten iron, in fixed proportions, steel of varying strengths are formed. Steel is strong since the carbon atoms enter the metallic lattice of iron the difference in size of the carbon and iron atoms restrict movement of the layers (atoms) hence when a force is applied, the steel resists. by 11SHIFT
Is A36 steel mild steel?
Yes. It is considered "Mild" Steel due to the low amount of carbon in the steel.
What is the difference between carbon steel and mild steel?
Carbon steel includes mild steel. Mild carbon steel(as it is referred to) contains .05 - .29% carbon. Medium carbon steel is from .30 - .59%. High carbon steel is from .60 - .99%. Ultra high carbon steel is from 1.00 - 2.00%. Steel is considered carbon steel up to 2.1%. Past that it is considered cast iron. The more carbon in the steel the harder and less ductile and maleable it is and also the more brittle it is. The less carbon in the steel more it will bend and shape without breaking. So in essence carbon adds strength but takes away from its elasticity.

What is difference between preheat and interpass temperature in welding?
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.
How do you calculate interpass temperature in welding?
Interpass temperature is the maximum temperature a weldment should be allowed to reach between weld passes. If a pass is completed and the temperature is in excess of the interpass, it should be allowed to cool before continuing.
Why temperature drop is high in low carbon steel than high carbon steel?
Because high carbon steel has low fluidity & low carbon steel has high fluidity.
What is the temperature range of low temperature carbon steel in which range of operating temperature it can be used?
Carbon Steel is used upto 427 oC or upto 1100 oF.
Does heat treatment increase the carbon content in carbon steel?
Heat increases the potential energy and temperature of steel.
How does increasing the amount of carbon in steel affect properties?
The melting point of steel goes down to a lower temperature when the proportion of carbon is increased. The steel becomes harder and is not as easy to weld as lower-carbon steel.
What is stronger low carbon steel or high carbon steel?
The amount of carbon in iron metal determines the strength and type of steel.Steel with low carbon is called low carbon steel and carbon with medium carbon called medium carbon steel. It is called low carbon steel if the carbon content is around 2.5 % or less. Others may be called medium or high carbon steel like that used in Die Steel of cutting tools. Generally low carbon steel are preferred if welding is adopted.
What physical state is steel at room temperature?
Steel is not an element it is a metallic alloy containing iron, carbon and other additives. At standard temperature and pressure it is a solid.
What are the phases of eutectoid steel at room temperature?
The lowest temperature at which austenite transforms into ferrite and cementite. Steel with 0.77 percent carbon transforms at this temperature. Learn more abouteutectoid temperaturein the classHeat Treatment of Steel 230below.
What is low carbon steel and high carbon steel?
Low carbon steel is steel with low carbon. High carbon steel is steel with high carbon
What is the difference between a234 and sa234?
a105 is forged carbon steel fittings and are used in ambient temperature or low temperature service whereas, a234 is wrought carbon steel/low alloy steel fitting used in moderate or elevated temperatures.
Why does the solubility of carbon in steel increase while heating?
Steel is mainly Iron with small amount of Nickel or/and chromium, carbon content of steel is about 2.5%. The increase in temperature increases the distance among the Iron atoms so carbon become accommodated easily in material.
