Standard grades

Grade Description
Globar SD
Elements suitable for most applications in which silicon carbide elements are used. Kanthal Globar SD SiC heating elements feature hot zones of recrystallized silicon carbide, optimized for resistance to oxidation and common process gases. Available in rod or multi-leg designs.
Globar AS
A Dense recrystallised SiC material with approximately 20% porosity, a high Weibull modulus, much stronger than SD and our competitors’ products and particularly useful in applications that are cyclical, long span, or subject to strong mechanical vibration.
Globar HD
SiC heating elements designed for the most challenging applications where conventional silicon carbide elements are unsuitable. Kanthal Globar HD SiC heating elements feature hot zones of high density, low permeability, reaction-bonded silicon carbide, which is highly resistant to oxidation, and to chemical attack by process volatiles and reactive atmospheres. Available in rod or multi-leg designs.
Globar SG and SR
Tubular spiralled SiC elements made from Kanthal Globar HD material.
