Definitions
- the present invention essentially relates to iron-base alloys of the type adapted for producing high-temperature operating slugs and exhibiting high mechanical strength, low creep, good resistance to corrosion and to thermal shocks in temperature ranges from about 800 C. to 1250 C., and principally capable of being very readilv welded by the various known industrial processes.
- allovs including nickel in a proportion of about 30 to and chromium in a proportion of about 23 to 27%.
- Such alloys have also a relatively low content of carbon, manganese, silicon, phosphorus and sulphur.
- the present invention aims at overcoming such drawbacks and diificulties by creating a new alloy meeting all of the hereinabove mentioned requirements, containing, besides iron, nickel, chromium, manganese, silicon and very little impurities, said alloy being remarkable especially in that it contains a relatively low quantity of niobium.
- the niobium content ranges substantially from 0.20% and 3.0% by weight.
- the niobium content is of about 0.3 to 2.0% by weight.
- the niobium content is of about 1.20% by weight.
- the components of the alloy conformable to the invention range within the following proportions:
- the alloy is free from tungsten and molybdenum. Indeed, it has been noted that, on the one hand, they were relatively expensive alloying elements and, on the other hand, they decreased rather than improved the qualities of the finished produce.
- EXAMPLE 1 Three tests were effected at a temperature of about 950 C. during 1000 hours and 10,000 hours to evaluate the action of the niobium on the properties of a hot base alloy including 33% of nickel and 25% of chromium. Carbon, manganese, silicon, iron and impurities were 3 present in the proportions corresponding to the hereabove indicated restricted composition.
- Table III clearly points out the peculiar characteristics of the alloy conformable to this invention. The best results are obtained with a limited addition of niobium alone and the addition of other alloying elements such as tungsten and molybdenum in the absence of niobium results in lower creep characteristics while still constituting a more expensive alloy. Likewise, tungsten-niobium and tungsten niobium molybdenum combinations do not present any technical or economical advantage.
- Admixtures of carbon were carried out in each sample, on every mm. deep slice through more than 1 mm.
- the richest layer was that located between 0.2 and 0.3 mm. from the surface.
- the layer located between 1 and 1.1 mm. indicated the intensity of the deep carburizing, the intermediate points being substantially proportional.
- Cementation time (in The invention also covers, by way of new industrial products, the produce obtained by means of the aforementioned alloy as well as its various applications.
- Iron-base alloy for making high-temperature working slugs, usuable at temperatures as high as l2001250 C., containing carbon, nickel, chromium and the minimum usual impurities, said alloy consisting essentially of: Carbonfrom about 0.10% to 0.60% by Weight Chromiurnfrom about 23% to 28% by weight Nickelfrorn about 30% to 36% by weight Niobiumfrom about 0.3% to 2% by weight Manganese-from about 0.8% to 2% by weight Siliconfrom about 0.8% to 2% by weight Nitrogen-from about 0.02% to 0.20% by weight References Cited the rest being iron and said usual impurities.
