Abstract
Gas cylinder composition of steel disclosed by the invention (weight %) is: 0.27～0.36%C, and 0.20～0.40%Si, 1.50～1.80%Mn ,≤0.040%P ,≤0.040%S, 0.07～0.14%V, all the other are iron.Steel of the present invention only need just can obtain the good comprehensive mechanical property by after the simple normalized thermal treatment, makes the gas cylinder bottle wall attenuate of its manufacturing, thereby has low cost of manufacture, and technology is simple, saves advantages such as the energy and facility investment.
Description
The invention belongs to the alloy technology field, relate to a kind of steel alloy for high-pressure tank of low-alloy high-strength.
In the prior art, highquality carbon steel, manganese steel develop into chromemolybdenum steel, steel nickel chrome, carbon boron steel to the material of manufacturing steel alloy for high-pressure tank.And stainless steel, and adopt modified thermal treatment or solutionizing to handle and realize industrial production.But, exist cost of alloy expensive, the manufacturing process complexity, facility investment is big, shortcomings such as steel production cost height.
The objective of the invention is, provide a kind of middle carbon to contain the steel alloy for high-pressure tank with high-yield strength, high tenacity of vanadium.
The composition of the said steel alloy for high-pressure tank of the present invention (weight %) is:
0.27～0.36%C，0.20～0.40%Si，1.50～1.80%Mn，
0.040%P, 0.040%S, 0.07～0.14%V, all the other are iron.
The said steel alloy for high-pressure tank of the present invention owing to add a spot of vanadium, makes its grain refining, has improved its yield strength effectively; Reduce the carbon amount simultaneously, its toughness is improved, thereby obtain the good comprehensive mechanical property.When designing, the gas cylinder wall thickness is reduced, add a small amount of vanadium, reduce the cost of steel with yield strength.Owing to only adopt normalizing thermal treatment, therefore save quenching high tempering operation, simplified technology, saved the energy and facility investment, also can avoid defectives such as quenching crack, decarburization.
The embodiment of the invention sees the following form:
