![]() Manganese – strength and hardness decreases ductility and weldability effects hardenability of steel.Significant other factors include cost, availability, and the ease of fabrication. Most steels with more than 2.5% carbon content are made using powder metallurgy.Ĭarbon steel is used in boilers, pressure vessels, heat exchangers, piping, and other moderate-temperature service systems in which good strength and ductility are desired.Used for special purposes like (non-industrial-purpose) knives, axles or punches. ![]() Steels that can be tempered to great hardness.Approximately 1.25–2.0% carbon content.Used as tool and die steels owing to the high hardness and wear resistance property.Strong carbide formers like Cr, V, W are added as alloying elements to from carbides of these metals.Used in hardened and tempered condition.High C content provides high hardness and strength.High carbon steels – Carbon content 0.6 – 1.4%.Typical applications – Railway wheels and tracks, gears, crankshafts.Heat treated alloys are stronger but have lower ductility.Addition of Cr, Ni, Mo improves the heat treating capacity.Medium carbon steels have low hardenability.Most often used in tempered condition – tempered martensite.Can be heat treated – austenitizing, quenching and then tempering.Carbon content in the range of 0.3 – 0.6%.High Strength, Low Alloy (HSLA) steels – alloying elements (like Cu, V, Ni and Mo) up to 10 wt % have higher strengths and may be heat treated.Not responsive to heat treatment cold working needed to improve the strength.Most abundant grade of steel is low carbon steel – greatest quantity produced least expensive.Plain carbon steels – very low content of alloying elements and small amounts of Mn.Super High carbon steel- Carbon content 2.5-3.0%Ĭommonly used Carbon Steel explained below:.High carbon steel- Carbon content 0.9-2.5%. ![]() Medium carbon steel- Carbon content 0.25-10.6%.Low carbon steel – Carbon content 0.55-1.05%.Carbon SteelĬarbon Steel Pipe can be classified into four categories: That essential difference is what gives carbon steel and stainless steel their distinct physical characteristics. Their main difference is alloy content-carbon steel has under 10.5 percent alloy content, while stainless steel must contain 10.5 percent chromium or more. Difference Between Carbon Steel and Stainless SteelĬarbon steel and stainless steel have the same basic ingredients of iron and carbon. ![]() In carbon steels, the higher carbon content lowers the melting point. Regardless of the heat treatment, a higher carbon content reduces weldability. The term “carbon steel” may also be used in reference to steel which is not stainless steel in this use carbon steel may include alloy steels.Īs the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating however, it becomes less ductile. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: Steel is considered to be carbon steel when: no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect the specified minimum for copper does not exceed 0.40 percent or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.
