Characteristics of metal protection tubes

Material Max. Application Temperature Characteristics
Carbon steel 550°C Satisfactory corrosion resistance, can be used in oxidizing and reducing atmospheres, but for a shorter period of time.
Nodular (pearlitic) cast iron 700°C Use on non-ferrous metals.
Stainless steel 304 900°C
Good resistance to oxidation and corrosion. Not recommended for use in the presence of sulfur or reducing flames. Subject to pitting corrosion.
Stainless steel 316 900°C Contains A, superior resistance to 304 stainless steel, acids and alkalis.
446 chrome steel 1100°C Excellent resistance to corrosion and oxidation at high temperatures, good resistance in sulfurous atmosphere. Applications in heat treatment furnaces.
Inconel 600 1150°C Excellent resistance to high temperature oxidation, good corrosion resistance, should not be used in sulfur-containing atmospheres (sulfuric) above 500°C
Stainless steel 310 1100°C Good mechanical strength, excellent corrosion resistance. Not recommended for use in sulphurous atmospheres.
Nicrobell D 1250°C Excellent mechanical resistance, oxidation and corrosion. Not recommended for use in sulphurous atmospheres.
Terasest 1260°C Excellent resistance to oxidation, corrosion and high temperature mechanics, superior to stainless steel and high nickel alloys, excellent resistance in carbonizing, reducing and vacuum atmospheres.
