Abstract
The invention relates to low alloy steel. The low alloy steel comprises the following chemical components in mass percent: 0.3-0.4% of carbon, 0.08-0.15% of silicon, 0.55-0.65% of manganese, less than or equal to 0.03 of phosphorus, less than or equal to 0.025% of sulfur, 1.12-1.25% of chromium, 1.28-1.40% of nickel and the balance of Fe. The low alloy steel has the advantages of high strength, simple formula and the like.
Description
Technical field
The present invention relates to field of alloy steel, relate in particular to a kind of low alloy steel.
Background technology
The alloying element total amount is called low alloy steel less than 3.5% steel alloy.Low alloy steel is for carbon steel, be on the basis of carbon steel, in order to improve one or more performances of steel, and add one or more alloying elements in the steel that has a mind, when the alloy amount that adds surpasses the general content that the normal production method of carbon steel has, claim that this steel is steel alloy.When being lower than 3.5%, the alloy total amount is called low alloy steel; Alloy content is called Medium Alloy Steel between 3.5-10%; The high quality steel that is called greater than 10%.
China's output of steel has been broken through 600,000,000 tons, and steel quantity no longer is principal contradiction, and the contradiction of rolling shapes unreasonable structure is very outstanding.The main task of current industry is to make great efforts to improve the competitiveness of product in market, stands on the ground zero of sustainable development, Devoting Major Efforts To Developing low alloy steel is listed in the important content of development strategy.Many general steel enterprise is in rolling shapes structural adjustment and establishment science and technology development planning, recognized that low alloy steel production is the key that improves technology content and added value of products, the variety of problems of running in the low alloy steel exploitation is felt unsure of, some scientific and technological management cadres feel " becoming also low alloy steel; lose also low alloy steel ", and an urgent demand has low alloy steel comprehensively to be understood.
The casting low-temperature steel that generally adopts at present both at home and abroad is Chromiumnickel Austenite Stainless Steel, and this class steel grade has good low-temperature toughness, but yield strength is low, far can not satisfying the market on to the intensity index requirement of low alloy steel.
Summary of the invention
Technical problem to be solved by this invention is: a kind of intensity height, the simple low alloy steel of filling a prescription are provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of low alloy steel, and the chemical ingredients of described low alloy steel and mass percent thereof are: carbon: 0.3-0.40%; Silicon: 0.08-0.15%; Manganese: 0.55-0.65%; Phosphorus :≤0.03%; Sulphur :≤0.025%; Chromium: 1.12-1.25%; Nickel: 1.28-1.40%, all the other form for iron.
The invention has the beneficial effects as follows: above-mentioned a kind of low alloy steel has intensity height, shock resistance is good and cost is low advantage.
Embodiment
Below by specific embodiment a kind of low alloy steel of the present invention is further described.
Embodiment one:
Carbon: 0.3%; Silicon: 0.15%; Manganese: 0.55%; Phosphorus: 0.03%; Sulphur: 0.025%; Chromium: 1.12%; Nickel: 1.40%, all the other form for iron.
Embodiment two:
Carbon: 0.40%; Silicon: 0.08%; Manganese: 0.65%; Phosphorus: 0.025%; Sulphur: 0.015%; Chromium: 1.18%; Nickel: 1.35%, all the other form for iron.
Embodiment three:
Carbon: 0.35%; Silicon: 0.12%; Manganese: 0.6%; Phosphorus: 0.02%; Sulphur: 0.02%; Chromium: 1.25%; Nickel: 1.28%, all the other form for iron.
