China 12Cr1MoV High Quality Alloy Structural Steel Plate

12Cr1MoV High Quality Alloy Structural Steel Plate. 12Cr1MoV, alloy structural steel. Uniform number code:A31132. Standard:GB/ t3077-1999. 2Cr1MoV is a kind of pearlite low alloy heat strength steel, which still has high heat strength and oxidation resistance at 580, and has a GB/T 11251 20Cr hot rolled structure steel plates - BBN SteelGB/T 11251 20Cr hot rolled structure steel plates can also be used in quenching and tempering condition to manufacture parts with larger working speed and medium impact load. GB/T 11251 20Cr hot rolled structure steel plates can also be used as low-carbon steel for martensitic quenching, which further increases yield strength and tensile GB/T 11251 20Cr hot rolled structure steel plates - Bebon GB/T 11251 20Cr hot rolled structure steel plates ,GB/T 11251 20Cr hot rolled structure steel plates are widely used to manufacture carburized parts (oil quenching) that have high requirements for core strength, bearing surface wear, section below 30mm, shape is complex and load is small. For example:machine transmission gear, gear shaft, cam, worm, piston pin, claw clutch.

GB/T 11251 35CrMnSiA hot rolled structure steel plates

But at the same time, its corrosion resistance and oxidation resistance is low. Therefore, GB/T 11251 35CrMnSiA hot rolled structure steel plates are usually used after low temperature tempering or equal temperature quenching. GB/T 11251 35CrMnSiA hot rolled structure steel plates GB/T 11251 40Cr hot rolled structure steel plates - Bebon The hardenability of the steel is good. GB/T 11251 40Cr hot rolled structure steel plate is also suitable for cyanidation and high frequency quenching in addition to quenching and tempering treatment. The cutting performance is better when the hardness is from HB174 to 229, the relative machinability is 60%.

The surface hardening after quenching and tempering is usually used as a heat treatment scheme. As a plastic mould steel, 42CrMo steel has excellent workability and good mechanical properties. Performance and application of 12Cr1MoV steel plate The carbon content of 12Cr1MoV steel plate is 0.12%. In addition, Cr, Mo and V microelements are specially added into the steel to regulate the properties of the 12Cr1MoV steel plate. 12Cr1MoV alloy steel is mainly used after normalizing and high temperature tempering to manufacture superheated steel pipe, conduit, serpentine tube and other

Pressure Vessel Forgings Pipe Accessories TongYu

Pressure vessel is designed to work under certain pressure, temperature and medium for a long time. So in addition to the high requirements on mechanical properties of vessels' material, it has also set standards upon pressure vessels' creep strength, temper embrittlement, corrosion resistance, as well as their performance under high/low temperature according to different applications and The characteristics and applications of GBT 11251 30CrMo GBT 11251 30CrMo structural steel has good machinability and medium plasticity during cold deformation; the first kind of tempering brittleness is in the range of 300~350 C during heat treatment, and has the tendency to form white spots. GBT 11251 30CrMo structural steel is usually used in quenched and tempered condition. The evolutions of microstructure and mechanical properties Jun 24, 2017 · The evolutions of microstructure and mechanical properties during tempering at 700 °C, of normalized and oil-quenched 2.25Cr-1Mo-0.25V steel samples to simulate the central and surface parts of the industrial heavy wall forgings, respectively, have been investigated.
