ASTM B444 GR 2 Inconel 625 cev

ASTM B444: This is the standard of the American Society for Testing and Materials (ASTM), which involves the standard specification of nickel-based alloy seamless pipes.
GR 2: Nanaša se na 2. razred, ki je v standardu . določena ocena
ASTM B444 GR 2 Inconel 625 Pipe je nikeljna brezhibna cev na osnovi niklja, ki temelji na zahtevah ameriške družbe za testiranje in materiale (ASTM) B444 Standardna ocena 2. Njegove temeljne komponente vključujejo nickel (približno58-60%), krom (približno20-23%), krom (približno20-23%), krom 8-10%) in majhna količina železa in niobija, ki ji daje odlično korozijsko odpornost, visoko temperaturno moč (delovna temperatura lahko doseže nad 980 stopinj), oksidacijsko odpornost in dobro vadbo; this standard specifies the manufacturing process of the pipe (such as seamless rolling), size range (common diameter is 6.35mm-323.85mm), mechanical properties (such as minimum yield strength 414 MPa, minimum tensile strength 827 MPa) and test requirements (such as pressure test, hardness test), Gr Grade 2 specifically refers to pipes that have been annealed to optimize toughness and formability, suitable for applications in harsh environments such as aerospace engine components, offshore engineering pipelines, chemical processing equipment, nuclear reactor heat exchangers, and oil and gas pipeline systems. It can effectively resist chloride stress corrosion cracking, seawater erosion, and high-temperature oxidation. In short, this Pipe je zaradi zanesljivosti in vsestranskosti postal izbirni material na visokozmogljivih industrijskih poljih.
