Alloy plate is a kind of steel plate with high thermal strength and oxidation resistance at high temperature, which has certain hydrogen corrosion resistance. Alloy plate is a new type of steel plate formed by adding other elements on the basis of steel plate material, which is to solve the problems existing in ordinary carbon steel plate. Alloy plate can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, silicon steel sheet, spring steel plate, NV D32 ore carrier steel, etc.
NV D32 ore carrier steel, Q345B low alloy steel has outstanding characteristics, such as: First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, NV D32 ore carrier steel, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.
Titanium microalloying is an element of NV D32 ore carrier steel strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in NV D32 ore carrier steel tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
Chemical composition of 42CrMo seamless steel pipe: C: 0.38-0.45, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.90-1.20, Mo: 0.15-0.25, V: 0.15-0.30. Mechanical properties of 42CrMo seamless steel pipe: tensile strength: 1080 MPa, yield strength: 930 MPa, elongation after fracture: 12%, reduction of area: 45%, impact energy: 63J. Due to the effect of carbon and chromium content, NV D32 ore carrier steel, 42CrMo seamless steel pipe has better strength and hardenability, higher fatigue strength and resistance to multiple impact after quenching and tempering, good impact toughness at low temperature and no obvious temper brittleness. It is generally used after quenching and tempering.
