Abstract
The invention belongs to the technical field of alloy steel, and relates to high temperature steel. The high temperature steel is mainly characterized in that: a small number of rare earth elements and some other trace elements are added into normal high temperature steel, so the using amount of the metal nickel is reduced, the performance of the high temperature steel exceeds that of the high temperature steel with high nickel content of the same type, and the production cost of the high temperature steel is reduced. The high temperature steel has the advantages of superior high temperature strength, high antioxidation, high corrosion resistance, high wear resistance, high creep resistance and high impact resistance; the maximum working temperature of the high temperature steel can reach 1,200 DEG C; and thus the high temperature steel can be widely applied to heat treatment accessories of industrial furnaces, furnace rollers, hearth plates, retorts, tanks, fan blade shafts, hangers, charging baskets, charging trays, heat-resistant lining plates, guide plates, lifting lugs, hooks, nozzles, slide blocks, pipe racks, guard plates of rotary cement kilns, lining plates, feeding pipes and the like.
Description
Affiliated technical field
The invention belongs to the steel alloy technical field, relate to a kind of high-temperature steel.
Background technology
In the prior art, high-temperature steel mainly with nickel chromium triangle as alloying element, be characterized in that nickel content is higher in the steel, and costing an arm and a leg of nickel makes that the production cost of high-temperature steel is very high.High-temperature steel model commonly used in the industry has: ZG45Ni35Cr26 and ZG35Cr28Ni48W5 etc., the content of nickel is higher in the invar, so the production cost of high-temperature steel is high always.
Summary of the invention
The purpose of this invention is to provide a kind ofly added that trace rare-earth element, nickel content are low, high temperature resistant, corrosion-resistant, wear-resistant, anti-oxidant, creep resistance, shock resistance, new type high temperature steel that production cost is lower, this high-temperature steel can substitute ZG45Ni35Cr26 and ZG35Cr28Ni48W5 uses, and performances such as the heat resistance of its steel and tension have all surpassed alternative steel grade.
In order to achieve the above object, a kind of new type high temperature steel of the present invention mainly is made up of C, Si, Mn, P, S, Cr, Ni, Mo, Al, Co, Ti, Nb, V, W, Pb, B, Re, As, Bi, Ca, Fe element, and the weight percent of its high-temperature steel chemical ingredients is: C0.1～0.5%; Si0.7～1.0%; Mn 1.0～1.2%; P0.0005～0.001%; S 0.005～0.006%; Cr 25～30%; Ni 25～30%; Mo0.40～0.45%; Al0.012～0.016%; Co 0.11～0.12%; Ti 0.001～0.0015%; Nb 0.6～0.8%; V 0.055～0.065%; W 2～6%; Pb 0.0002～0.00025%; B 0.0005～0.0006%; Re 0.0065～0.0075%; As 0.0001～0.00013%; Bi 0.0001～0.00014%; Ca0.0015～0.0025%; Fe 43～45.5%.
Embodiment:
The raw material of above-mentioned high-temperature steel is added in the medium-frequency induction furnace according to proportioning, it is smelted into molten steel and is cast into ingot, steel ingot is forged caused bar then, again bar is processed into sample and tests.
High-temperature steel of the present invention and existing high-temperature steel performance comparison test table look-up
The high-temperature steel performance that high-temperature steel of the present invention as can be seen from the above table is higher than similar trade mark nickel content is superior.
The invention has the beneficial effects as follows:
Add hot strength and anti-carburizing energy and high temperature oxidation resistance that sub-Nb, Mo and Re have improved steel in this high-temperature steel, reduced the consumption of Ni, it is low to have reduced production cost, and this steel high temperature resistant, corrosion-resistant, wear-resistant, anti-oxidant, creep resistance, shock resistance are better than the higher high-temperature steel of similar nickel content
Embodiment 1. is to drop in the intermediate frequency inductor with the raw material of high-temperature steel as following weight percent: C 0.5%; Si 1%; Mn 1%; P 0.0005%; S 0.005%; Cr 25%; Ni 25%; Mo 0.45%; Al 0.012%; Co 0.11%; Ti 0.001%; Nb 0.6%; V 0.062%; W 3%; Pb 0.0002%; B 0.0005%; Re 0.0071%; As0.0001%; Bi 0.0001%; Ca 0.0015%; Fe 43.25%, and it is smelted into molten steel and is cast into steel ingot, and this steel ingot is high-temperature steel.
Claims (2)
1. high-temperature steel, it is characterized in that the chemical ingredients of steel and weight percent are: C 0.1～0.5%; Si 0.7～1.0%; Mn 1.0～1.2%; P 0.0005～0.001%; S 0.005～0.006%; Cr 25～30%; Ni 25～30%; Mo 0.40～0.45%; Al 0.012～0.016%; Co 0.11～0.12%; Ti 0.001～0.0015%; Nb 0.6～0.8%; V 0.055～0.065%; W 2～6%; Pb 0.0002～0.00025%; B 0.0005～0.0006%; Re0.0065～0.0075%; As 0.0001～0.00013%; Bi 0.0001～0.00014%; Ca0.0015～0.0025%; Fe 43～45.5%.
