lus 945

Incoloy 908 yog ib qho alloy raws li npib tsib xee nrog ntxiv ntawm lwm cov khoom. Incoloy 908, Monel alloy muaj txog 30% tooj liab tsim nyob ib puag ncig xyoo 1905, yog cov nickel alloy ua ntej. Incoloy 908 npib tsib xee muaj cov khoom siv zoo, lub cev thiab tshuaj lom neeg. Ntxiv cov ntsiab lus tsim nyog tuaj yeem txhim kho nws cov oxidation tsis kam, corrosion kuj, kub siab zog thiab txhim kho qee yam khoom ntawm lub cev. Incoloy 908 npib tsib xee alloy tuaj yeem siv los ua cov khoom siv rau cov raj hluav taws xob, cov hlau nplaum precision (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys and shape memory alloys, thiab lwm yam. Incoloy 908 Nickel alloys tau siv dav hauv kev tsim kho hluav taws xob, tshuaj lom neeg kev lag luam, hluav taws xob, navigation, aviation thiab aerospace sectors.

Incoloy 945 yog lub zog muaj zog, corrosion-resistant alloy tsim rau kev thov hauv kev lag luam roj thiab roj. Cov ntsiab lus ntawm molybdenum, tooj liab, niobium, titanium thiab txhuas txhim kho cov khoom ntawm lub hnub nyoog-hardenable nickel-hlau-chromium alloy.

Cov ntsiab lus npib tsib xee hauv cov alloy tiv thaiv kev ntxhov siab corrosion los ntawm chlorides. Kev sib xyaw ua ke ntawm cov npib tsib xee nrog molybdenum thiab tooj liab kuj tseem muab Alloy 945 zoo heev tiv thaiv kev xeb hauv kev txo cov xov xwm. Molybdenum kuj tseem tiv thaiv qhov chaw hauv cheeb tsam corrosion (pitting thiab crevice corrosion). Cov ntsiab lus chromium hauv cov hlau ua rau nws tiv taus oxidizing ib puag ncig. Niobium, titanium thiab txhuas muaj kev koom tes hauv lub hnub nyoog hardening cov tshuaj tiv thaiv uas tshwm sim thaum kho cua sov. Lawv cov kev sib cuam tshuam ua rau precipitates ntawm gamma thiab gamma bis, yog li ntxiv dag zog rau cov hlau.

Nws yog austenitic stainless hlau. Vim nws cov ntsiab lus molybdenum siab, nws muaj qhov siab tshaj plaws rau pitting corrosion thiab crevice corrosion. Qib stainless hlau no tau tsim los siv rau hauv ib puag ncig uas muaj halides xws li dej hiav txwv. 254SMO kuj tseem muaj kev tiv thaiv zoo rau kev xeb. Tshwj xeeb tshaj yog nyob rau hauv cov kua qaub uas muaj halides, cov hlau no zoo dua li cov hlau tsis zoo li qub. Nws cov ntsiab lus C yog<0.03%, so it is called pure austenitic stainless steel. It is also called super austenitic stainless steel. Super stainless steel is a kind of special stainless steel. First of all, it is different from ordinary stainless steel in chemical composition. It refers to a high alloy stainless steel containing high nickel, high chromium and high molybdenum. Among them, the most popular one is 254SMo containing 6% Mo. This type of steel has very good resistance to local corrosion. It has good pitting corrosion resistance (PI ≥ 40) and relatively high resistance to seawater, air, gaps, and low-speed erosion conditions. With good stress corrosion resistance, it is a substitute material for Ni-based alloys and titanium alloys. Secondly, in terms of high temperature resistance or corrosion resistance, it has better high temperature resistance or corrosion resistance, which is irreplaceable for 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenite metallographic structure. Since this special stainless steel is a high-alloy material, the manufacturing process is quite complex. Generally, people can only rely on traditional processes to manufacture this special stainless steel, such as pouring, forging, rolling, etc.
