产品名称
INCOLOY 800H & 800HT
产品描述
Nickel-iron-chromium alloys that have the same basic composition as INCOLOY alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum and titanium contents in conjunction with a hightemperature anneal. Used in chemical and petrochemical processing, power plants for super-heater and reheater tubing, industrial furnaces and heat-treating equipment.
STANDARD PRODUCT FORMS
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging
stock, hexagon and wire.
