Product Specification

Hot-Rolling UNS N10675 Hastelloy B3 Pipe SCH 5 - SCH XXS ASTM B163/ASME SB-163

1.Hastelloy B3 description

Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion,

and stress-corrosion cracking plus, thermal stability superior to that of alloy B-2. In addition,

this nickel steel alloy has great resistance to knife-line and heat–affected zone attack. Alloy B-3

also withstands sulfuric, acetic, formic and phosphoric acids, and other non-oxidizing media.

Furthermore, this nickel alloy has excellent resistance to hydrochloric acid at all concentrations

and temperatures. Hastelloy B-3’s distinguishing feature is its ability to maintain excellent

ductility during transient exposures to intermediate temperatures. Such exposures are routinely

experienced during heat treatments associated with fabrication.

6.Hot-Rolling Steel

Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature

over 1700° F), which is above the steel’s recrystallization temperature. When steel is above the

recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger

sizes. Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured

without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold

rolled). When the steel cools off it will shrink slightly thus giving less control on the size and shape of the

finished product when compared to cold rolled.

Uses: Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make

railroad tracks and I-beams, for example. Hot rolled steel is used in situations where precise shapes and

tolerances are not required.
