Virgin Engineers is an Carbon Steel LF2 Forged Steel Valves manufacturer and distributor and exporter delivering it to the whole world. We are an ISO accredit supplier providing products with globally approved standards. Offered forged steel valves have an excellent quality that completely meets the customer's requirements. The carbon steel forged steel valves offered by us accepted by our esteemed customers in the wide section of engineering and industrial applications.
We specialize in producing forged steel valves in standard and altered dimensions as per the specific requirements of the customers.
It is general carbon steel is supplied in the normalized, tempered and quenched conditions. It is characterized by having impact toughness and moderate strength and it is extensively used for manufacturing of forged steel valves. These are applied in the applications that require cold temperature service where the corrosion resistance is the concern.
The carbon steel is capable of manufacturing products by hot and cold processing. The forging temperature of the material is between 900 deg C to 1200 deg C also it should be kept minimum to prevent scaling, however, but sufficient time should be provided to allow the center to attain furnace temperature. After, the forging operations the material is processed from the quenching process with water.
The normalizing is done in the temperature between 860 deg C to 920 deg C for a time equal with the ruling section. The air cooling is performed if required. The hardening is done in temperature between 890 deg C to 960 deg C and quenched with water. The tempering or re-heating process is done in the temperature up to 590 deg C and keeps minimal as required. The hold time for an appropriate ruling section and cool in still in the air is required.
Carbon Steel LF2 has very good machinability, dependent on end condition, and operations such as sawing, broaching, turning, milling, etc. This can be accomplished satisfactorily using conventional machine tool that needs standard speeds and feeds.
Carbon Steel LF2 Forged Steel Valves are readily weldable by any technique such as resistance, arc and fusion welding.
The production of forged steel valves begins from the testing of crude materials. The primary tests are performed on raw materials that are material tests includes pitting corrosion test, IGC test, positive material test, micro test, macro test, and radiographic test. On manufactured products destructive testing is performed those are burst tests, fire safety tests, valve seat leakage test, hydrostatic test, backseat test, pneumatic test, and closure test. other tests are shell leakage test, cryogenic testing, low temperature testing, high temperature test, functional tests, drill stem test, traveling valve test, etc.
We provide some guides and credentials along with the supplied range of products as quality proof. Those are specification guide, product invoice, mill test reports, attests certificates and more.
Carbon Steel LF2 Forged Steel Valves are available in treated surfaces and finishes customers can buy from us at most reasonable rates.
