Standard grades

Grade Description
Globar® SD Elements suitable for most applications in which silicon carbide elements are used. 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. 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 Globar® HD material.
