Definitions
- Patent Document 4 discloses an austenitic stainless steel, excellent in creep characteristics and hot workability, which satisfies the three relationships, namely the relationship between P and Cu, the relationship between sol. Al and N, and the relationship between O and Cu, respectively.
- the Non-Patent Document 3 describes investigations made in search of means for preventing intergranular cracking in the HAZ in the welded portion of 18Cr-8Ni-Nb type austenitic stainless heat resistant steels, if heated for a long period of time.
- Mn like Si, has a deoxidizing effect. Mn also contributes toward stabilization of the austenite phase. However, when the content thereof is excessive, in particular at a content level exceeding 2.0%, it causes embrittlement and thus deteriorates the creep ductility and toughness. Therefore, the content of Mn is set to not more than 2.0%. More preferably, the content of Mn is not more than 1.5%.
- Cr is an essential element for ensuring the oxidation resistance and corrosion resistance at high temperatures and, in order to obtain the said effects, it is necessary that the Cr content be not less than 15%. However, when the content thereof is excessive, in particular at a content level exceeding 30%, it deteriorates the stability of the austenite phase at high temperatures and thus causes a decrease in creep strength. Therefore, the content of Cr is set to 15 to 30%.
- the preferable lower limit of the Cr content is 16% and the preferable upper limit thereof is 28%.
- Each of Cu, Mo, W, Co, Ta, Zr and Hf being elements of the first group, if added, has the effect of enhancing the high temperature strength.
- the said elements may be added to the steels and thereby contained therein. The elements, which are in the first group, are now described in detail.
- the cold working may be carried out after the hot working.
- the cold working may include the cold drawing pipe manufacturing process in which the pipe produced by the above-mentioned hot working is subjected to drawing and/or the cold rolling pipe manufacturing process using a cold pilger mill.
- the cold working may include the typical process of manufacturing a cold rolled steel sheet in coil.
- the final heat treatment after the above-mentioned hot working or the final heat treatment after a further cold working following the hot working may be carried out at a heating temperature of not less than 1030°C.
- the upper limit of the said heating temperature is not particularly defined, but a temperature exceeding 1350°C may cause not only high temperature intergranular cracking or a deterioration of ductility but also very coarse grains. Moreover, the said temperature may cause a marked deterioration of workability. Therefore, the upper limit of the heating temperature is preferably set to 1350°C.
