AISI 4140 steel is Chrome-Moly High Tensile Steel which includes at the very least .8%Cr,.15%Mo as strengthening alloy elements.The chromium content provides good hardness penetration, and also the molybdenum content ensures uniform hardness and strength. AISI 4140 steel can be oil hardened to your relatively high level of hardness with a tensile strength of 850 – DIN 1.7225 offers a very good balance of strength,toughness and wear-resistance.Compared with AISI 4130,it possesses a slightly higher carbon content which provides greater strength and also heat treatment capabilities , nevertheless it is poor in weldability. Pre hardened and tempered 4140 could be further surface hardened by flame or induction hardening(can be surface hardened to a typical value 58HRC)and by nitriding( Surface hardness achievable is 600 to 650HV).

AISI 4140 alloy steel has good machinability,operations such as turning, hobbing, drilling, sawing, broaching, tapping and milling can easily be performed utilizing the recommendations supplied by the machine’s manufacturer for ideal tool type-feeds and speeds. AISI 4140 is normally used for a variety of applications in the oil and gas ,aerospace,automotive, agricultural and defense industries.

Worldwide fabricators who supply the oil, gas and petrochemical industry, require highest specification steels for use within the output of weldable steel pressure vessels and industrial boilers. 16Mo3, which is supplied under the EN 10028 euro norm specification, is among these steels.

16Mo3 is actually a chrome molybdenum based steel which has excellent heat resistance and corrosion resistant characteristics. Therefore alone, the steel is a well-known within the manufacture of pressurised vessels and boilers. The material offers good welding properties when using conventional welding methods and due to the materials excellent heat resistance, 16Mo3 is also utilized in pipework for transporting hot liquids.

Added chromium within the steel increases the corrosion resistance whilst the larger molybdenum content promotes the rise in potential to deal with elevated temperatures. 16Mo3 also offers good hot and cold forming properties and it is normally delivered in ‘as rolled’ condition. Consideration should be made concerning the degree of tensile strength required before procuring AISI 4340 – whilst the material offers good overall tensile strength, this strength decreases as the temperature rises.

Equivalents for this particular steel grade can be found under both ASTM and ASME steel specifications for chrome moly (A387 and SA387 respectively). 16Mo3 is also extensively employed by the inshore and offshore industry. Material of the type normally comes with mill certification and stamping and additional testing is normally supplied on the customers request. This can be achieved by vjrryg third party testing house or independently inspected from the customer.

The petrochemical industry sets very high demands for carbon steel grades found in their production facilities that is unsurprising considering that the working environment is potentially such a hazardous one. The business dictates quality standards for the use of steel within these production plants with all the emphasis placed heavily on operational safety. Any material supplied must conform fully with all the test criteria specified and the like criteria varies dependent on the particular type of steel sought. Chrome Molybdenum is certainly one particular steel type that is popular within the industry.

About Chrome Molybdenum Steel – Also referred to as C45E, this particular type of steel can be used for many different purposes including the fabrication of industrial boilers and pressure vessels. Chrome Moly has two key advantages. High temperature tensile strength – chrome moly is an ideal material to use in elevated temperature environments. Corrosion & Oxidation Resistance- chrome moly offers excellent resistance to the consequences of corrosion and oxidation.

The steel itself is produced on the steel mill with higher levels of chromium and molybdenum – the chromium supplies the corrosion and oxidation resistance whilst the molybdenum offers heat resistance. It is therefore clear to find out why such a steel is popular within the oil and gas industry where high working temperature in pressurized conditions are common place.
