General characteristics of Stainless Steel 330

Type 330 is an austenitic high-temperature alloy that is resistant to carburizing atmospheres and to thermal cycling

Applications

The grade is suited to applications that will take advantage of its resistance to carburization, oxidation and thermal shock. The grade was actually designed for the heat treatment industry where it finds use as muffles, retorts and radiant tubes.

Forging

The grade may be forged between 2100/1750ÂşF (1150/950ÂşC.) Forged parts should be cooled as quickly as possible, and for best corrosion resistance post-forge annealing is recommended.

Heat treatment

Annealing is carried out at around 2050ÂşF (1120ÂşC) followed by water quenching.

Machinability

The usual precautions should be observed, namely low speeds and strong feeds, to overcome the work hardening effects of the material.

Weldability

Type 330 may be welded using normal fusion and resistance methods. Advice should be taken regarding the type of filler metal to be used.
