Description
NIMONIC alloy 105 (UNS N13021/W. Nr. 2.4634) is a forged Ni-Co-Cr base alloy and strengthened by additions of Mo,AI & Ti.It can work up to 950°C. Alloy 105 combines the high strength of the age-hardening nickel-base alloys with good creep resistance. For critical applications,the alloy is produced by vacuum melting and electroslag refining.The alloy is used for turbine blades, discs, forgings, ring sections, bolts and fasteners.
Product Features
Forms & Specifications
Standards: ASTM B637, MSRR 7004, 7022, 7063, 7070, 7162, 7193, 7952, BS: HR 203, 3HR1, HR2, HR3, HR4, BS4HR 601
This alloy has good ductility and may be readily formed by all conventional methods. Because the alloy is stronger than regular steel it requires more powerful equipment to accomplish forming. Heavy-duty lubricants should be used during cold forming. It is essential to thoroughly clean the part of all traces of lubricant after forming as embrittlement of the alloy may occur at high temperatures if lubricant is left on.
