Observation:Medium carbon low alloy forged steel vs. polymer quenched and tempered steels have strong influence on fracture toughness(KIC).The polymer quenched and tempered steels results high fracture toughness value for as forged samples. The microstructure of forged sample consists of proeutectoid ferrite and pearlite.
AISI 1045 Medium Carbon Steel - AZoM
MachiningWeldingHeat TreatmentApplicationsAISI 1045 steel has good machinability in a normalized or hot-rolled condition. Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing can be carried out on AISI 1045 steel using suitable feeds, tool type, and speeds.Difference Between Low, Medium & High Carbon SteelDec 14, 2019 · Medium carbon steel is a carbon steel with a carbon percentage content of 0.25% (or 0.29%) to 0.60%. It includes most of the quality carbon steel and a portion of the plain carbon steel. Typical medium carbon steels include:US ASTM SAE AISI 1030, 1034, 1035, 1038, 1040, 1042, 1043, 1045, 1050, 1055, etc.
Medium Carbon Steel The carbon content is 0.29%-0.54% carbon, with a manganese content of 0.6%-1.65%. This is a stronger steel with good wear resistance, but its a bit trickier to form, weld, and cut. Medium carbon steels can be heat treated and tempered.

Carbon SteelsHigh-Strength Low-Alloy SteelsLow-Alloy SteelsThe Four Types of Steel Metal SupermarketsMar 23, 2015 · Medium Carbon Steel:Typically has a carbon range of 0.31% to 0.60%, and a manganese content ranging from .060% to 1.65%. This product is stronger than low carbon steel, and it is more difficult to form, weld and cut. Medium carbon steels are
EP0899352A1 - Medium/high carbon low alloy steel for A medium/high carbon low alloy steel which can be cold formed by cold or warm forging and heat treated. The material consists essentially of:Element Weight Percent Carbon (C) about 0.45-0.65 Manganese (Mn) about 0.35-0.45 Chromium (Cr) about 0.70-0.80 Nickel (Ni) about 0.35-0.50 Molybdenum (Mo) about 0.15-0.30 ium (Ti) about 0.01-0.02 Aluminum (Al) about 0.01-0.02
Medium-Carbon Steels Medium-carbon steels are similar to low-carbon steels except that they contain carbon from 0.30% to 0.60% and manganese from 0.60% to 1.65%. Increasing the carbon content to approximately 0.5% with an accompanying increase in manganese allows medium-carbon steels to be used in the quenched and tempered condition.

Plain Carbon SteelsLow-Alloy SteelsHigh-Alloy SteelsSteel Classification SystemsMachining Low- and Medium-Carbon Steel AlloysNov 13, 2020 · Low-carbon and medium-carbon steels form the backbone of virtually every shops operations in their general engineering applications and fabricated parts. What defines them is the percentage of carbon in the steel; 0.15 to 0.30 percent for low-carbon mild steel and 0.30 to 0.60 percent for medium-carbon steel.
SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent AISI 4340 steel (UNS G43400) is an ultra-high strength medium carbon low alloy steel, which combines deep hardenability, high ductility, toughness and strength, and
Jul 31, 2014 · Alloyed steels are harder, more durable and more resistant to corrosion. Alloy steels with carbon levels of medium to elevated rates are difficult to weld. However, if the carbon levels are reduced to 1% to 3%, such alloy metals can achieve greater formability and weldability, thus, improved strength.Metallurgical Materials Science and Alloy Design - Medium Medium Mn steels establish an imnportant class of novel alloys in the 3rd generation of advanced high strength steels (AHSS). These alloys have a manganese content between 3-12 wt.% and often multiple phase-like microstructure ingredients and phases. They show a good combinations of high to ultra-high strength at quite high total elongation.
