Type 308—used as the filler metal when welding 304. Type 309—better temperature resistance than 304, also sometimes used as filler metal when welding dissimilar steels, along with inconel. Type 310 310S— is a highly alloyed austenitic stainless steel used for high temperature application. The high chromium and nickel content give the ...
If a low-carbon steel is only stressed to some point between the upper and lower yield point then the surface develops Lüder bands. [7] Low-carbon steels contain less carbon than other steels and are easier to cold-form, making them easier to handle. [3] Typical applications of low carbon steel are car parts, pipes, construction, and food cans ...
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
Steel with a high carbon content will reach a much harder state than steel with a low carbon content. Likewise, tempering high-carbon steel to a certain temperature will produce steel that is considerably harder than low-carbon steel that is tempered at the same temperature. The amount of time held at the tempering temperature also has an effect.
When the carbon equivalent is between 0.40 and 0.60 weld preheat may be necessary. When the carbon equivalent is above 0.60, preheat is necessary, postheat may be necessary. The following carbon equivalent formula is used to determine if a spot weld will fail in high-strength low-alloy steel due to excessive hardenability: [2]

Medium-carbon steel This steel has more forking than mild steel and a wide variety of spark lengths, with more near the grinding wheel. [5] High-carbon steel High-carbon steel has a bushy spark pattern (much forking) that starts at the grinding wheel. The sparks are not as bright as the medium-carbon steel ones. [5] Manganese steel
Oxy-acetylene can cut only low- to medium-carbon steels and wrought iron. High-carbon steels are difficult to cut because the melting point of the slag is closer to the melting point of the parent metal, so that the slag from the cutting action does not eject as sparks but rather mixes with the clean melt near the cut.
