In addition to iron and carbon, stainless steel also adds alloying elements such as chromium and nickel, which have an important influence on the corrosion resistance and hardness of stainless steel. Hardness range: Carbon steels have a wide range of hardness, from low to high. Stainless steels have varying hardnesses, from low for austenite to .
ASTM A36 Steel. ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%).. A36 mild steel is often compared to AISI 1018, A36 carbon steel is commonly hot rolled, while 1018 steel is commonly cold rolled.. Notes: There are two .

Unlike other types of steel, carbon steel does not have a minimum. . One of the key characteristics of ultra-high carbon steel is its hardness. With a hardness typically above 60 HRC, ultra-high carbon steel is one of the hardest materials available. .Low-carbon steel, also known as mild steel is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications. Low-carbon steel contains approximately 0.05–0.25% carbon making it malleable and ductile. . Brinell hardness test is one of indentation hardness .The Vickers hardness test is ideal for testing of all metals and is therefore the method with the widest range of application.

Brinell’s hardness test and Charpy impact test were used to measure the mechanical properties which is a function of the material’s quality and conformity. Samples of carbon steel AISI 1035 of dimension 55 mm by 10 mm with a notch of 2 mm deep and angle of 45o were prepared with the thickness varying in the range of 2 to 4 mm. D2 has a relatively high amount of carbon in its composition (1.55%), more than twice as much as AEB-L (0.68%), but most of that carbon goes into making chromium carbides instead of into solution in the steel matrix, leaving D2 with only ~0.5% C in solution and very large carbides that are good for wear resistance but bad for toughness.
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: . no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying .

Hardness testing is the simplest and most straightforward method among mechanical property tests. In order to replace certain mechanical property tests with hardness tests, a relatively accurate conversion relationship between hardness and strength is needed in production.. Experience has shown that there is .
Strength is a critical factor in metal uses, for example, some applications require stronger aluminum parts, while some products need high steel hardness or yield strength of steel, this may determine the selection of CNC machining material or product design.
