42CrMo steel is a Chinese alloy steel, and has high strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering treatment, it has high fatigue limit and resistance to multiple impacts, and good low temperature impact toughness.


Detailed

A good combination of hardness, hardenability, and toughness of 42CrMo steel can be achieved by alloying with adding some content of C and Ni. Detailed content of carbon and Ni should be on the requirements of heat treatment properties of steel for bearing ring of varisized shield tunneling machine.


Detailed

42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.


Detailed

42CrMo4 can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. electroslag, forged ring/ block,etc. TEL:+86

A wide variety of 42crmo hardness options are available to you, such as free samples, paid samples. There are 3,107 42crmo hardness suppliers, mainly located in Asia. The top supplying countries are China (Mainland), South Korea, and Turkey, which supply 99%, 1%,


Detailed

AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).

Engineering steel material EN19 hardness in HRCFlame or induction hardening can give a case hardness of 50 HRC or higher. EN19 equivalent material with AISI 4140, DIN 42CrMo4 EN 1.7225, GB 42CrMo, JIS SCM440C alloy engineering steel. Mechanical properties of steel EN19 (1.7225)


Detailed

The addition of 0.03 wt% C into 42CrMo steel can increase the hardness. But it reduces the impact energy by 46 J because of the appearance of coarser carbides in the matrix and the carbides along the austenite grain boundary. The addition of 0.40 wt% Mn into 42CrMo steel can improve hardenability.


Detailed

Aug 15, 2007 · What hardness scale was used to obtain the 60HRC value? If it was not a direct HRC perhaps the carbon penetration is shallow at worst. As far as heat treating process selection, 42CrMo is similar to 4140 as far as alloying is concerned, in general neither one is carburized.


Detailed

AISI 4140 is defined as a low alloy steel which has 1% Cr Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28 32HRC.


Detailed

This material achieves a very good balance between strength, toughness and wear resistance. The chromium content of the alloy provides good hardness permeability, and the molybdenum element imparts average hardness and high strength.SCM440 reacts well in heat treatment and it is easy to process under heat treatment conditions.
