What is alloy 800 HT rod used for?
Applications where temperatures can reach 1100° F, are where Alloy 800HT Flat Bar is most frequently used. Even when exposed to heat for extended periods at temperatures between 1200 and 1600 °F, where many stainless steels are brittle, it won’t become brittle.
Alloy 800 HT Rod is frequently used in applications that:
- Require prolonged exposure to high temperatures
- Require resistance to oxidation and carbonization
These alloys are used for outlet manifolds, pigtails, convection tubing, and catalyst tubing in the hydrocarbon processing sector’s steam/hydrocarbon reforming process.

Inconel 800HT Bars and 800HT (UNS N08811) are certifiable dual nickel-iron-chromium alloys that resist tarnishing, carburizing, and other forms of corrosion at high temperatures. A class of nickel-chromium-based superalloys known as Inconel is distinguished by:
- High resistance to corrosion
- Oxidation resistance, and
- High-temperature resistance
There are three reasons why the same can withstand high temperatures and corrosive environments.
- Equipment for the production of ethylene used in chemical and petrochemical processes.
- Vapour/hydrocarbon reformers and hydrodealkylation units are used in petroleum refining.
- Steam superheaters and coal-fired power plant piping systems are used for power generation.

Is titanium better than ASTM B408 UNS N08811 square bar?
The high strength-to-weight ratio of titanium as a metal is well known. It is a solid low-density metal that is metallic-white in hue, quite ductile (especially in an oxygen-free environment), and lustrous. It works well as a refractory metal due to its relatively high melting point (1668°C or 3034°F). Below is a comparison between titanium and ASTM B408 UNS No 8811 Rod.
Titanium characteristics
- Outstanding resistance to corrosion
- Fantasticstrength-to-weight ratio
- Light heat resistance
- Powerful heat transfer
Mechanical Properties of ASTM B408 UNS N08811 Square Bar

Can you weld nickel alloy 800HT shaft?
Most nickel alloys are fusion weldable using gas-shielded techniques like TIG or MIG. The SAW process is limited to Nickel Alloy 800HT Shaft and is less popular among the flux processes, whereas MMA is frequently used. A typical arc welding procedure that involves the formation of is called submerged-arc welding (SAW). This is made possible by an arc between a continuously fed electrode and the workpiece. Nickel and its alloys are weldable using all conventional welding techniques, and corresponding welding consumables are readily available.

Is DIN 1.4859 square bar magnetic?
In addition to having exceptional mechanical properties, DIN 1.4859 Square Bars can operate in a variety of pressures and temperatures. The minimum yield strength of these parts is 275 MPa, and their minimum tensile strength is 600 MPa. The purpose of these round bars is to raise the temperature for use in architectural applications. It offers all-around resistance to machinery used for chemical processing. They are very affordable to machines and have excellent weldability and formability. These bars meet the DIN specification thanks to the heat treatment procedure at moderate temperatures. Consequently, they can have magnetic or non-magnetic properties.
