الصين مصنع خاص سبائك النيكل الصلب عالية الجودة Inconel 718 للبتروكيماويات والمصفاة

Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures. This nickel alloy is used from cryogenic temperatures up to long term service at 1200° F.

One of the distinguishing features of Inconel 718’s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling. The addition of niobium acts with the molybdenum to stiffen the alloy’s matrix and provide high strength without a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium.

This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.

مقدمة مادية
Inconel® Alloy 718 is a high-strength, corrosion-resistant, precipitation hardened Ni-Cr alloy containing niobium and molybdenum, which can be used at -423° to 1300°F. Its age-hardenable ability can be readily fabricated,even into complex parts. Its welding characteristics,especially its resistance to postweld cracking, are outstanding.

It has high strength, good toughness and corrosion resistance in high and low temperature environments at temperatures below 650 °C. The state can be solution treatment or precipitation hardening state.
