16Cr25Ni20Si2 Heat-Resistant Stainless Steel
16Cr25Ni20Si2 heat-resistant stainless steel
16Cr25Ni20Si2 heat-resistant stainless steel has high high-temperature strength and oxidation resistance, and is more sensitive to sulfur-containing atmospheres. It has a tendency to embrittlement of precipitated phases at 600-800 ℃. It is suitable for making various furnace components under stress.
