HASTELLOYC4est mixtura ex Nickel, chromium, et molybdenum. Magnopere reputatur stannum versatile pro corrosione pugnans. Hoc stannum resistentiam demonstrat formationi frumenti limitis praecipitat calori glutino subiecta, eamque aptam facit ad varias applicationes chemicae in statu suo iunctas. Accedit, AlloyC4egregie resistentiam exhibet ad colligationem, corrosionem accentus, rimas, et atmosphaeras oxidizationes usque ad 1900°F. Eximia resistentia in chemicis ambitus amplis habet.
APPLICATIONS:
